The document discusses injuries to the acromioclavicular (AC) joint. It provides details on the anatomy and biomechanics of the AC joint and surrounding ligaments. Common mechanisms of injury include falling on an outstretched arm or direct force to the lateral shoulder. Injuries are classified using the Rockwood system from Type I to VI based on the degree of ligament disruption and bone displacement. Treatment options include nonoperative measures for lower grades and surgery for higher grades or failed nonoperative treatment. Surgical techniques and associated conditions are also reviewed.
CORA (center of rotation of angulation)Morshed Abir
This document discusses the concept of the center of rotation of angulation (CORA) in orthopedic surgery. The CORA is the point about which a deformed bone may be rotated to achieve correction of an angular deformity without introducing a translational deformity. Proper identification of the CORA allows selection of the optimal correction axis and type of osteotomy, such as opening, closing, or dome osteotomy, to realign the bone. Correction along the bisector line passing through the CORA ensures pure angular correction without residual translation. Identification of multiple CORAs indicates more complex multi-apical or translational deformities requiring different surgical techniques.
Acromioclavicular (AC) joint injury is a term used to describe an injury to the top of the shoulder, where the front of the shoulder blade (acromion) attaches to the collarbone (clavicle).
This document discusses various osteotomies around the hip joint. It begins with defining osteotomy and providing a brief history of important developments. It then explains the biomechanics of the hip joint and why osteotomies are effective. Several types and classifications of osteotomies are outlined.

It begins by outlining common causes for revision TKR such as aseptic loosening and polyethylene wear. Key challenges in revision TKR are managing bone defects from osteolysis, compromised soft tissues, and restoring proper limb alignment. Implant options discussed include metaphyseal sleeves and stems to provide fixation in bone defect zones, as well as augmentations. Constraint levels from unconstrained to fully constrained implants are reviewed. Clinical cases demonstrate approaches for addressing instability, significant bone loss, and peri-prosthetic fractures in revision TKR.
This document discusses septic arthritis of the hip in children. It defines septic arthritis and notes that the hip is the most commonly infected joint in children. Early diagnosis and treatment is important to prevent joint damage. Signs include limping, groin pain, and limited hip movement. Treatment involves identifying the organism, administering sensitive antibiotics, and potentially surgery. Long term sequelae can include joint deformities, leg length discrepancies, and arthritis. Various classification systems and treatment approaches are presented. Prevention of septic arthritis through early diagnosis and management is emphasized.
Ligamentotaxis principle in the treatment of intra articular fractures of dis...Sitanshu Barik
This study assessed the correlation between radiological outcomes and functional outcomes in 45 patients treated with external fixation for intra-articular fractures of the distal radius. Good or acceptable restoration of radial length and palmar slope on radiographs post-operatively was found to produce good to excellent functional results regardless of fracture type. While poor radiological outcomes did not always lead to poor function, maintenance of radial length and correction of palmar tilt were important for functional outcomes. The study concluded that achieving good function is more important than surgical precision on radiographs alone.
Tips, tricks and pitfalls of proximal femoral nailing (PFN)Puneeth Pai
1. Proximal femoral nailing (PFN) requires thorough pre-operative planning including imaging and assessment of fracture pattern and patient comorbidities.
2. It is important to reduce the fracture before making the entry point, as the entry point will determine surgical success.
3. Factors such as varus reduction, medializing the shaft, high tip-apex distance, and penetration of the femoral head can lead to poor outcomes like nonunion.
The "terrible triad" refers to an elbow dislocation with fractures of the coronoid process and radial head. This is an extremely unstable injury that often leads to recurrent instability, stiffness, and arthritis. Surgical treatment aims to address all fractures, repair ligaments, and restore stability through techniques like internal fixation, replacement, and external fixation. Postoperative rehabilitation focuses on early range of motion while protecting the repair.
Osteotomies around the hip are surgical procedures used to correct biomechanical alignment and load transmission across the hip joint. They involve removing a portion of bone. The goals are to improve femoral head coverage, containment, motion, relieve pain, and correct leg length discrepancies. Different types of osteotomies target the proximal femur or pelvis. Proximal femoral osteotomies are classified based on anatomical location and degree of displacement. Pelvic osteotomies aim to redirect the acetabulum and include Salter, Sutherland, Steel/Tonnis, and Ganz/Bernese procedures. Key considerations for each procedure include indications, approach, osteotomy cuts made, advantages/disadv
This document summarizes the evolution of intramedullary nails for long bone fracture fixation from the 16th century to modern times. It describes the early use of wooden sticks and ivory implants, the introduction of metallic rods during WWI, and the development of modern locked intramedullary nails in the mid-20th century. Key figures who advanced nail design include Kuntscher, who introduced reamed nailing in 1940, and Russell and Taylor, who developed the first closed section interlocking nail in the 1980s. The document outlines the progression from first to fourth generation nails, incorporating improvements in materials, locking mechanisms, and designs to optimize stability and healing.
This document provides information on acromioclavicular (AC) joint injuries. It discusses the anatomy and biomechanics of the AC joint. It also outlines the epidemiology, mechanisms of injury, clinical evaluation, classification systems and treatment options for different grades of AC joint separation. For acute injuries under 4 weeks, treatment options discussed include conservative management or surgical stabilization techniques like hook plates, tightropes or ligament reconstruction. For chronic injuries, options include AC joint excision or reconstruction of the coracoclavicular ligaments.
This document discusses zonal CME conducted at GSLMC on the superior shoulder suspensory complex (SSSC). It defines the SSSC as a bony and soft tissue ring structure that maintains the stable relationship between the scapula and axial skeleton. Injuries to two structures in the SSSC can cause instability known as the "floating shoulder". Treatment depends on the amount of displacement, with conservative management used for displacements under 5mm and no caudal displacement of the glenoid. Surgical stabilization is recommended for larger displacements or malalignment.
Osteotomy around the elbow is commonly performed to correct cubitus varus and cubitus valgus deformities. For cubitus varus, the most common cause is a malunited supracondylar fracture. Surgical options include lateral closing wedge osteotomy, oblique osteotomy with derotation, and medial opening wedge osteotomy with bone grafting. For cubitus valgus, causes include nonunion of a lateral condyle fracture. Surgical options are a closing wedge medial osteotomy or opening wedge lateral osteotomy. Complications of elbow osteotomy can include stiffness, persistent deformity, myositis ossificans, loss of fixation, and neurovascular injury.

This document provides an overview of acromioclavicular joint dislocations. It begins with definitions and epidemiology, then reviews the anatomy and mechanisms of injury. It describes how to clinically evaluate and classify AC joint dislocations using Rockwood's classification system. Treatment depends on the type of dislocation, ranging from rest for minor injuries to open reduction and surgical repair for more severe injuries. Potential complications are also discussed.
This document discusses different types of shoulder dislocations including acute, recurrent, anterior, posterior, and inferior dislocations. It covers the anatomy of the shoulder joint, mechanisms of injury, clinical presentation, treatment including closed and open reduction techniques, and complications. Recurrent dislocations are more common in younger patients. Posterior dislocations are rare but the diagnosis is often missed on initial x-ray. Inferior dislocations involve severe abduction forces and risk neurovascular injury.
Here are the key steps in the ORIF procedure:
1. Patient is placed in lateral decubitus position and a right-angled lateral incision is made to minimize soft tissue damage.
2. The fracture line at the angle of Gissane is identified.
3. Fragments are temporarily held in place with K-wires under fluoroscopy while the reconstruction restores the 3D shape of the calcaneus.
4. The "constant" sustentacular fragment is used to begin the reconstruction, working anteriorly and medially.
5. Traction may be needed to restore the posterior facet.
6. The lateral wall fragment is closed like a door last to complete the
Recurrent shoulder dislocation and managementAnshul Sethi
This document provides an overview of recurrent shoulder dislocations. It discusses the anatomy of the shoulder joint and its stabilizers. The glenohumeral ligaments, labrum, rotator cuff muscles, and negative intra-articular pressure provide static stability, while dynamic stability comes from the rotator cuff and scapulo-thoracic motion. Younger age, returning to collision sports, and bone defects increase risk of recurrence. Evaluation involves assessing range of motion, translation, and special tests like the anterior drawer and sulcus sign. History and physical exam help determine treatment which may include rehabilitation or surgery to address labral tears or bone loss.
This document discusses congenital pseudarthrosis of the tibia (CPT), a rare condition where the tibia fails to heal after fractures at an early age. CPT is often associated with neurofibromatosis type 1. The etiology is unclear but is thought to involve periosteal fibrosis. Imaging can help evaluate the extent of disease. Surgical treatment aims to achieve union, prevent refracture, and correct deformities. Common approaches include intramedullary nailing, vascularized fibular grafting, and external fixation. Prognosis remains poor due to risks of nonunion, refracture, limb length discrepancy, and ankle deformity. Close long-term monitoring is needed.
The document discusses injuries to the acromioclavicular (AC) joint. It covers the anatomy of the AC joint and surrounding ligaments. It then discusses the classification system for AC joint injuries, which ranges from Grade I to Grade VI, with higher grades indicating greater ligament disruption and bone displacement. Treatment options are covered, including initial immobilization for lower grades and surgical reconstruction or fixation for higher grades. Surgical techniques like ligament repair/reconstruction and coracoclavicular screw fixation are summarized. Associated shoulder issues like fractures are also mentioned.

Fractures around elbow lateral condyle and intercondylar fracturesSiddhartha Sinha
1) Lateral condyle fractures and intercondylar fractures of the elbow involve fractures around the lower end of the humerus.
2) Lateral condyle fractures, which account for 17% of distal humeral fractures in children, often require fixation to prevent nonunion. Intercondylar fractures in adults involve a T or Y-shaped fracture through the two humeral condyles.
3) Treatment depends on the type and severity of the fracture, ranging from casting for nondisplaced fractures to open reduction and internal fixation for displaced fractures to prevent long-term complications like nonunion and deformity.
Fractures around elbow lateral condyle and intercondylar fracturesSiddhartha Sinha
Fractures around the elbow include lateral condyle fractures and intercondylar fractures. Lateral condyle fractures involve the lateral epicondyle and account for 17% of distal humeral fractures in children. They often result in less satisfactory outcomes than supracondylar fractures due to missed diagnoses and loss of motion. Intercondylar fractures involve a T or Y-shaped fracture line through the two humeral condyles and comminution is common. Both fracture types are typically treated operatively with open reduction and internal fixation to restore the joint surface and columns. Complications can include post-traumatic arthritis, failure of fixation, loss of motion, and neurologic injury.

Clavicle fractures are common injuries, especially in young active individuals. The majority occur in the midshaft region due to its thin bone and lack of muscle protection. Treatment depends on the location and degree of displacement/shortening. Nondisplaced fractures are usually treated nonsurgically with slings or strapping. Displaced fractures may require plate fixation, intramedullary nails, or coracoclavicular ligament repair/reconstruction to achieve union and restore function. Complications can include nonunion, malunion, hardware irritation, and neurovascular injury.
RECURRENT SHOULDER DISLOCATION. DR. DHARAMPAL SWAMIDR. D. P. SWAMI
This document provides an overview of recurrent shoulder dislocation and operative intervention. It begins with a brief history of shoulder dislocation documentation and treatment. It then discusses the pathoanatomy, risk factors, classifications, and open vs arthroscopic surgical procedures for recurrent shoulder dislocation. Key open surgical techniques discussed include the Bankart procedure, capsular shift procedure, Putti-Platt procedure, Magnuson-Stack procedure, Bristow procedure, and Latarjet procedure. The document examines factors in determining the optimal treatment approach and whether open or arthroscopic stabilization is superior.
Pelvic fractures can be classified based on their stability and the mechanism of injury. Unstable and partially stable fractures often require surgical fixation while stable fractures may be treated non-operatively. Initial management focuses on controlling hemorrhage through fluid resuscitation, pelvic binding, angiography, or preperitoneal packing. Definitive treatment is then aimed at anatomic reduction and stabilization of the pelvis through external or internal fixation depending on the fracture pattern and stability. Close monitoring for complications such as infection, neurological injury, or persistent instability is important.

Ventilation Perfusion Ratio, Physiological dead space and physiological shuntMedicoseAcademics
In this insightful lecture, Dr. Faiza, an esteemed Assistant Professor of Physiology, delves into the essential concept of the ventilation-perfusion ratio (V˙/Q˙), which is fundamental to understanding pulmonary physiology. Dr. Faiza brings a wealth of knowledge and experience to the table, with qualifications including MBBS, FCPS in Physiology, and multiple postgraduate degrees in public health and healthcare education.
The lecture begins by laying the groundwork with basic concepts, explaining the definitions of ventilation (V˙) and perfusion (Q˙), and highlighting the significance of the ventilation-perfusion ratio (V˙/Q˙). Dr. Faiza explains the normal value of this ratio and its critical role in ensuring efficient gas exchange in the lungs.
Next, the discussion moves to the impact of different V˙/Q˙ ratios on alveolar gas concentrations. Participants will learn how a normal, zero, or infinite V˙/Q˙ ratio affects the partial pressures of oxygen and carbon dioxide in the alveoli. Dr. Faiza provides a detailed comparison of alveolar gas concentrations in these varying scenarios, offering a clear understanding of the physiological changes that occur.
The lecture also covers the concepts of physiological shunt and dead space. Dr. Faiza defines physiological shunt and explains its causes and effects on gas exchange, distinguishing it from anatomical dead space. She also discusses physiological dead space in detail, including how it is calculated using the Bohr equation. The components and significance of the Bohr equation are thoroughly explained, and practical examples of its application are provided.
Further, the lecture examines the variations in V˙/Q˙ ratios in different regions of the lung and under different conditions, such as lying versus supine and resting versus exercise. Dr. Faiza analyzes how these variations affect pulmonary function and discusses the abnormal V˙/Q˙ ratios seen in chronic obstructive lung disease (COPD) and their clinical implications.
Finally, Dr. Faiza explores the clinical implications of abnormal V˙/Q˙ ratios. She identifies clinical conditions associated with these abnormalities, such as COPD and emphysema, and discusses the physiological and clinical consequences on respiratory function. The lecture emphasizes the importance of understanding these concepts for medical professionals and students, highlighting their relevance in diagnosing and managing respiratory conditions.
This comprehensive lecture provides valuable insights for medical students, healthcare professionals, and anyone interested in respiratory physiology. Participants will gain a deep understanding of how ventilation and perfusion work together to optimize gas exchange in the lungs and how deviations from the norm can lead to significant clinical issues.
Chemical kinetics is the study of the rates at which chemical reactions occur and the factors that influence these rates.
Importance in Pharmaceuticals: Understanding chemical kinetics is essential for predicting the shelf life of drugs, optimizing storage conditions, and ensuring consistent drug performance.
Rate of Reaction: The speed at which reactants are converted to products.
Factors Influencing Reaction Rates:
Concentration of Reactants: Higher concentrations generally increase the rate of reaction.
Temperature: Increasing temperature typically increases reaction rates.
Catalysts: Substances that increase the reaction rate without being consumed in the process.
Physical State of Reactants: The surface area and physical state (solid, liquid, gas) of reactants can affect the reaction rate.

A comparative study on uroculturome antimicrobial susceptibility in apparentl...Bhoj Raj Singh
The uroculturome indicates the profile of culturable microbes inhabiting the urinary tract, and it is often required to do a urine culture to find an effective antimicrobial to treat UTIs. This study targeted to understand the profile of culturable pathogens in the urine of apparently healthy (128) and humans with clinical UTIs (161). In urine samples from UTI cases, microbial counts were 1.2×104 ± 6.02×103 colony-forming units (cfu)/ mL, while in urine samples from apparently healthy humans, the average count was 3.33± 1.34×103 cfu/ mL. In eight samples (six from UTI cases and two from apparently healthy people) of urine, Candida (C. albicans 3, C. catenulata 1, C. krusei 1, C. tropicalis 1, C. parapsiplosis 1, C. gulliermondii 1) and Rhizopus species (1) were detected. Candida krusei was detected only in a single urine sample from a healthy person and C. albicans was detected both in urine of healthy and clinical UTI cases. Fungal strains were always detected with one or more types of bacteria. Gram-positive bacteria were more commonly (OR, 1.98; CI99, 1.01-3.87) detected in urine samples of apparently healthy humans, and Gram -ve bacteria (OR, 2.74; CI99, 1.44-5.23) in urines of UTI cases. From urine samples of 161 UTI cases, a total of 90 different types of microbes were detected and, 73 samples had only a single type of bacteria. In contrast, 49, 29, 3, 4, 1, and 2 samples had 2, 3, 4, 5, 6 and 7 types of bacteria, respectively. The most common bacteria detected in urine of UTI cases was Escherichia coli detected in 52 samples, in 20 cases as the single type of bacteria, other 34 types of bacteria were detected in pure form in 53 cases. From 128 urine samples of apparently healthy people, 88 types of microbes were detected either singly or in association with others, from 64 urine samples only a single type of bacteria was detected while 34, 13, 3, 11, 2 and 1 samples yielded 2, 3, 4, 5, 6 and seven types of microbes, respectively. In the urine of apparently healthy humans too, E. coli was the most common bacteria, detected in pure culture from 10 samples followed by Staphylococcus haemolyticus (9), S. intermedius (5), and S. aureus (5), and similar types of bacteria also dominated in cases of mixed occurrence, E. coli was detected in 26, S. aureus in 22 and S. haemolyticus in 19 urine samples, respectively. Gram +ve bacteria isolated from urine samples' irrespective of health status were more often (p, <0.01) resistant than Gram -ve bacteria to ajowan oil, holy basil oil, cinnamaldehyde, and cinnamon oil, but more susceptible to sandalwood oil (p, <0.01). However, for antibiotics, Gram +ve were more often susceptible than Gram -ve bacteria to cephalosporins, doxycycline, and nitrofurantoin. The study concludes that to understand the role of good and bad bacteria in the urinary tract microbiome more targeted studies are needed to discern the isolates at the pathotype level.
Mainstreaming #CleanLanguage in healthcare.pptxJudy Rees
In healthcare, every day, millions of conversations fail. They fail to cover what’s really important, fail to resolve key issues, miss the point and lead to misunderstandings and disagreements.
Clean Language is one approach that can improve things. It’s a set of precise questions – and a way of asking them – which help us all get clear on what matters, what we’d like to have happen, and what’s needed.
Around 1000 people working in healthcare have trained in Clean Language skills over the past 20+ years. People are using what they’ve learnt, in their own spheres, and share anecdotes of significant successes. But the various local initiatives have not scaled, nor connected with each other, and learning has not been widely shared.
This project, which emerged from work done by the NHS England South-West End-Of-Life Network, with help from the Q Community and especially Hesham Abdalla, aims to fix that.

POTENTIAL TARGET DISEASES FOR GENE THERAPY SOURAV.pptxsouravpaul769171
Theoretically, gene therapy is the permanent solution for genetic diseases. But it has several complexities. At its current stage, it is not accessible to most people due to its huge cost. A breakthrough may come anytime and a day may come when almost every disease will have a gene therapy Gene therapy have the potential to revolutionize the practice of medicine.

Hepatocarcinoma today between guidelines and medical therapy. The role of sur...Gian Luca Grazi
Today more than ever, hepatocellular carcinoma therapy is experiencing profound and substantial changes.
The association atezolizumab (ATEZO) plus bevacizumab (BEVA) has demonstrated its effectiveness in the post-operative treatment of patients, improving the results that can be achieved with liver resections. This after the failure of the use of sorafenib in the already historic STORM study.
On the other hand, the prognostic classification of BCLC is now widely questioned. It is now well recognized that the indications for surgery for patients with hepatocellular carcinoma are certainly narrow in BCLC and no longer reflect what is common everyday clinical practice.
Today, the concept of multiparametric therapeutic hierarchy, which makes the management of patients with hepatocellular carcinoma much more flexible and allows the best therapy for the individual patient to be identified based on their clinical characteristics, is gaining more and more importance.
The presentation traces these profound changes that are taking place in recent years and offers a modern vision of the management of patients with hepatocellular carcinoma.
Ontotext’s Clinical Trials Eligibility Design Assistant helps with one of the most challenging tasks in study design: selecting the proper patient population.
3. Applied Anatomy
• A plane synovial joint, located between medial margin
of acromion and lateral end of clavicle
• Within the AC joint, there is a fibro cartilaginous disc
5. Acromioclavicular Ligaments
• Consists of anterior, posterior, superior, and inferior
ligaments, surround the AC joint
• Stabilize the joint in horizontal plane
• Superior AC ligament- strongest of capsular ligaments,
blend with fibers of the deltoid and trapezius muscles
adding stability to AC joint.
6. Coracoclavicular Ligament
• Very strong ligament from outer inferior surface of
clavicle to base of the coracoid process of scapula.
• Two components—conoid and trapezoid ligaments
• Vertical stability of AC joint
7. • The only connection between the upper extremity
and the axial skeleton is through the clavicular
articulations at the AC and SC joints.
• SC ligaments support clavicles suspended away from
the body
• CC ligament suspend upper extremities from distal
clavicles
8. • CC ligament helps to
couple glenohumeral
abduction/flexion to
scapular rotation on thorax
during overhead elevation
• Clavicle rotates around 40-
50 degrees during full
overhead elevation--
simultaneous scapular
rotation and AC joint
motion
9. Overview
• Injuries to either AC or SC joints can result in a wide
range of shoulder dysfunction.
• Both can be injured by similar mechanisms, present
with overlapping clinical complaints, and in some
cases result in injury to both locations
• Acromioclavicular injures are more common, and
sternoclavicular injuries are rare
10. Risk groups
• often occur in male patients less than 30 years of age
• associated with contact sports or athletic activity in which direct blow
to lateral aspect of shoulder occurs.
• The contact or collision athlete represents a “high-risk” individual
(football, rugby, and hockey)
• AC joint injuries accounted for 4.5% of all injuries (and 32% of all
shoulder injuries) in a population of NCAA football players followed
for 5 years. Of the 748 injuries to the AC joint recorded, the vast
majority (96%) were “low-grade” injuries, classified as type I or II
sprains
11. Mechanisms of Injury
• Falling on an outstretched arm, locked in extension at
the elbow, can drive humeral head superiorly into
acromion--low-grade AC joint injuries
• A medially directed force to lateral shoulder that
drives acromion into and underneath the distal
clavicle(when getting checked into the boards during
a hockey game)- higher degrees of injury and
subsequently more displacement.
12. • More commonly described pattern- falling or being
tackled onto lateral aspect of the shoulder with the arm
in an adducted position which produces a compressive
(medial) and shear (vertical) force across the joint-
typically produces higher degree of displacement enough
to tear both AC and CC ligaments.
13. • The injury force which drives acromion medially and downward
produces a progressive injury pattern; first disruption of AC ligaments,
followed by disruption of CC ligaments, and finally disruption of fascia
overlying the clavicle that connects deltoid and trapezius muscle
attachments.
• Complete AC dislocation- the upper extremity has lost its suspensory
support from clavicle and scapula- inferior displacement of the
shoulder secondary to forces of gravity.
14. Nontraumatic or Chronic Overuse
• AC joint arthrosis—weight lifting, laborer, repetitive overhead activity
• Repetitive low-grade AC joint injuries
• Medical cause: rheumatoid arthritis, hyperparathyroidism,
scleroderma
15. Clinical presentation
• Young-aged male
• Contact or collision athlete
• H/O direct trauma
• Clinical deformity, focal tenderness and swelling
• Commonly the patient describes pain originating from the anterior-
superior aspect of the shoulder
16. Diagnosis
• Examination should be in sitting or standing w/o support for the injured
arm
• Check for tenderness to palpation at the AC joint and the CC interspace
• If patient can tolerate check joint for stability
• Check to see if reducible
• Examine SC joint as well
• Neurologic exam to r/o brachial plexus injury
19. Clinical triad
• point tenderness at the AC joint,
• pain exacerbation with cross-arm adduction, and
• relief of symptoms by injection of local anesthetic
agent confirm injury to the AC joint.
20. Imaging
• Good-quality radiographs of the AC joint require one-
third to one-half the beam penetration to image the
glenohumeral joint.
• Radiographs of the AC joint taken using routine
shoulder technique will be overpenetrated (i.e.dark),
and small fractures may be overlooked.
Therefore,specifically requested to take radiographs
of “AC joint” rather than the “shoulder.”
21. Radiographic Normal Joints
• Width and configuration of AC joint in coronal plane
may vary significantly from individual to individual. So,
a normal variant should not be mistaken as an injury.
• Normal width of AC joint in coronal plane is 1 to 3 mm.
AC joint space diminishes with increasing age (0.5 mm
in older than 60 years is conceivably normal). Joint
space of greater than 7 mm in men and 6 mm in
women is pathologic.
• Average CC distance 1.1 to 1.3 cm. An increase in CC
distance of 50% over normal side signifies Complete AC
dislocation (has been seen with as little as 25% increase
in CC distance).
22. Zanca View
• Beam placed 10
degrees cephalad
• Obtained using soft
tissue technique in
which voltage is cut
into half
• quantifying CC
distance, and
percentage
displacement of distal
clavicle above
acromion.
29. Type of Injury Clinical Features Radiological Features
Type I minimal to moderate tenderness to palpation over the AC joint
mild swelling over the AC joint
minimal pain with arm movements
respond very well to local anesthetic/ corticosteroid injections
No widening,separation or
deformity
Type II • moderate to severe tenderness with palpation of the joint
• Distal end of clavicle slightly superior to acromion
• Adduction motion of the shoulder produces pain in the AC joint
• Difficulty sleeping
• AC horizontal Instability
• Tenderness at CC space
<50% width of clavicle
displacement at AC joint
Increased CC distance < 25% of
contralateral
Type III • Upper extremity held adducted in elevated position
• shoulder droop sign
• Clavicle may be prominent enough to tent the skin.
• Moderate pain -any motion of the arm, particularly abduction
• Tenderness at AC joint, CC interspace, and along superior aspect
of lateral clavicle.
• AC joint instability in both the horizontal and vertical planes
• “shrug test” (vs type V)
Distal clavicle Displaced
Increased CC distance 25-100% of
contralateral
May be accompanied by Fracture
coracoid > Stryker View
30. Type of Injury Clinical Features Radiological Features
Type IV • All clinical findings of type III injury.
• clavicle is translated posteriorly compared with uninjured
shoulder may be “buttonholed” through trapezius muscle
and tents posterior skin.
• AC joint cannot be reduced manually
• Examine SC joint “bipolar” or “floating clavicle” injuries,
Best Observed in Axillary View
Lateral clavicle displaced posterior through
trapezius
Type V • Distal end of clavicle grossly superiorly displaced, tenting
the skin
• Downward Displacement of Upper Extremity
• More Pain than Type III secondary to more soft tissue
disruption.
• Shoulder musculature becomes weak secondary to disuse
or as part of the injury pattern-scapular dyskinesis
Zanca View
Increased CC distance > 100% of contralateral
Type VI • superior aspect of shoulder has flat appearance
• acromion is prominent
• associated fractures of clavicle,upper ribs or injury to upper
roots of brachial plexus
• Mechanism :Severe Hyperabduction and ER + retraction of
scapula
Subacromial type - decreased CC distance,
distal clavicle in subacromial location.
Subcoracoid type - reversed CC distance,
clavicle displaced inferior to coracoid process
34. • Children and adolescents may
sustain a variant of complete
AC dislocation (most often
Salter–Harris type I or II)
• Radiographs reveal
displacement of distal
clavicular metaphysis
superiorly (through a dorsal
rent in periosteal sleeve) with
increase in CC interspace.
Epiphysis and intact AC joint
remain in their anatomic
locations
35. Treatment goals
• Pain-free shoulder movement in a range-of-motion arc approaching
normal
• Unimpaired daily activities
36. Treatment Options
Nonoperative Treatment
• Indications-
Type I,II,III AC injuries
• Relative contraindications-
-Chronic symptomatic injury
-Failed nonoperative management, athlete, polytrauma, heavy
laborers
37. During 1st week of treatment
• Immobilization device (Arm slings, adhesive tape strappings, braces
and plaster)-
To support the weight of upper extremity and reduce the stress
placed upon the injured ligaments
• Ice and analgesics
To reduce pain and inflammation
38. After 1 to 2 weeks
• Strengthening exercises commenced with particular focus on
periscapular muscles that are important to shoulder
biomechanics.
• Heavy stresses, lifting, and contact sports should be delayed
until there is full range of motion and no pain to joint palpation.
This process can take up to 2 to 4 weeks
• Athletes who desire an earlier return to sports should be
encouraged to use protective padding over the AC joint. An
earlier return to sports that sustains a second injury to the AC
joint, prior to complete ligament healing, can change a partially
subluxated AC joint into a complete AC dislocation. Given this
possible sequela, a forewarning must be provided to all athletes
wishing to return to play at an earlier time. This decision is a
balance between the desire to return to play early and the risk
of reinjury.
39. DISADVANTAGES OF NON OPERATIVE
TREATMENT
• SKIN PRESSURE AND ULCERATION
• RECURRENCE OF DEFORMITY
• WEARING A BRACE FOR LONG TIME(8
WEEKS)
• POOR PATIENT COOPERATION
• INTERFERENCE WITH DAILY ACTIVITIES
• LOSS OF SHOULDER AND ELBOW MOTION
• SOFT TISSUE CALCIFICATIONS
• LATE ACROMIOCLAVICULAR ARTHRITIS
• LATE MUSCULAR ATROPHY,FATIGUE AND
WEAKNESS.
40. Type III- operative or nonoperative ?
• In prospective randomized studies between operative and
nonoperative treatment of type III AC joint injuries, patients treated
nonoperatively demonstrated a quicker return of function and
sustained fewer complications than patients treated operatively.
• Patients treated conservatively returned to work on average 2.1
weeks from injury and the strength and ROM of the injured shoulder
were comparable to the contralateral uninjured shoulder with a
mean follow-up of 2.6 years (Wojtys and Nelson)
• Operatively treated AC injuries showed a significantly higher
incidence of osteoarthritis and CC ligament ossification
• A proportion of conservatively treated patients will have persistent
pain and inability to return to their sport or job. Subsequent surgical
stabilization has allowed return to sport or work in such cases
41. Reasons for lower-grade AC joint injuries being
symptomatic –
• posttraumatic arthritis
• posttraumatic osteolysis of the distal clavicle,
• recurrent AP subluxation,
• torn capsular ligaments trapped within the joint,
• loose pieces of articular cartilage,
• detached intra-articular meniscus or associated intra-
articular fracture fragment.
42. Chronic Acromioclavicular Injuries
• Chronic pain after type I and II injuries- NSAIDS, avoidance of painful
activity or positions, and intra-articular injection with corticosteroid
• Type I-
Operative excision of distal clavicle (limited to less than 10 mm )-open or
arthroscopic
• Type II-
Distal clavicle excision + AC capsular reconstruction or coracoacromial
ligament transfer
• Chronic pain and instability after types III, IV, and V- Distal clavicle
excision + Transfer of acromial attachment of coracoacromial ligament to
the resected surface of distal clavicle and concurrent CC stabilization
43. Operative Treatment
Indications -
• Patients (types I,II,III) who have failed a minimum 6
weeks of shoulder stabilization–directed physical
therapy (delayed surgical reconstruction using a
tendon graft)
• Active healthy patients with complete AC joint injuries
(types IV, V, and VI)- significant morbidity associated
with the injury pattern- persistently dislocated,
unstable AC joint, with change in scapular kinematics,
and shoulder dysfunction.
• Fracture of coracoid extending intra-articularly into
glenoid (5 mm or more of glenoid displacement )
44. • Fixation across AC joint
• Fixation between coracoid and
clavicle
• Ligament reconstruction
• Distal clavicle excision
45. ANY SURGICAL PROCEDURE FOR AC JOINT
DISLOCATION SHOULD FULFILL THREE REQUIREMENTS
• AC JOINT MUST BE EXPOSED AND DEBRIDED
• CC AND AC LIGAMENTS MUST BE
REPAIRED OR RECONSTRUCTED
• STABLE REDUCTION OF THE AC JOINT MUST BE
OBTAINED
Achievingthese three goals , no matter how the joint is
fixed , should give acceptable results.
46. DISADVANTAGES OF SURGICAL
MANAGEMENT
• INFECTION
• HEMATOMA FORMATION
• ANAESTHETIC RISK
• SCAR FORMATION
• RECURRENCE OF DEFORMITY
• METAL BREAKAGE,
LOOSENING,MIGRATION
• SECOND SURGERY FOR REMOVAL
• BREAKAGE OR LOOSENING OF
SUTURES
• EROSION OR FRACTURE OF DISTAL
CLAVICLE
50. Fixation between coracoid and clavicle
• Bosworth popularized the use of a screw for fixation
of the clavicle to the coracoid
• This technique initially did not include
recommendation for repair or reconstruction of the CC
ligaments
• Today the use of screws and suture loops has been
described alone and in combo with ligament
reconstruction
• Placement of synthetic loops between the coracoid and
clavicle can be done arthroscopically, main advantage:
doesn’t require staged screw removal
53. Ligament reconstruction
• Weaver and Dunn were the 1st to describe transfer for the
native CA ligament to reestablish AC joint stability
• Their technique described excision of the distal clavicle with this
ligament transfer
• Construct can be augmented with a suture loop for protection until
the
transferred ligament heals
Open or Arthroscopy
55. Anatomic Ligament Reconstruction
• Alternative technique is use of semitendinosus autograft for
reconstruction
– Loop around or fix into coracoid, then fix through two separate clavicle
bone tunnels to approximate normal anatomic location of CC
ligaments
• Recent biomechanical studies have demonstrated the superiority
of this
construct
56. Anatomic Coracoclavicular Ligament Reconstruction
• ACCR technique attempts to restore biomechanics of
AC joint complex as treatment for painful or unstable
dislocations
• Rationale- to reconstruct both CC ligaments by
anatomically fixing a tendon graft in two clavicle
tunnels placed in the anatomic insertion site of conoid
and trapezoid ligaments.
• In addition, AC ligaments are reconstructed with the
remaining limb of the graft exiting the more lateral
trapezoid tunnel.
57. ACCR technique: patient positioning
• Far lateral position with shoulder free to extend, small
scapula bump along medial scapula border, and head
position extended and rotated away from operative side.
58. ACCR-Steps
• Vertical incision centered on clavicle (starting from
posterior clavicle to just medial of coracoid process
)approx 3.5 cm medial to AC joint.
• Subperiosteal flaps raised to ensure that trapezius and
deltoid attachments are elevated off. Tagging stitches can
be placed to aid in tight closure of this layer during
closure.
59. • Conoid tunnel position marked at least 45 mm from
distal clavicle
• Trapezoid tunnel position marked with at least 25 mm
of bone bridge between tunnels
• Tunnels drilled
60. • Graft passed through
tunnel,beneath coracoid
• Interference fixation with
PEEK screws
(polyetheretherketone)
• Continue brace for 8 weeks
• Strengthening exercises
from 12 weeks
61. • Graft options- semitendinosus allograft/autograft, Anterior tibialis
allograft.
• Semi-tendinosus allograft preferred -simplification of patient
positioning, no donor site morbidity, decreased operative time,
consistency in graft tissue size
• The minimal length needed to ensure graft available for AC ligament
reconstruction approx 110 mm.
63. • Glenohumeral Intra-Articular Pathology Pauly et al. noted a 15%
incidence of intra-articular pathology, SLAP and PASTA(Partial articular
supraspinatus tendon avulsion) lesions, in their series of 40
consecutive patients undergoing arthroscopic-assisted reconstruction
of grade III to V AC joint dislocations
64. Fractures
• lateral clavicle fracture
• base or neck of coracoid process fracture
• concomitant injury to medial clavicular epiphysis (less than 30 years
of age)
• Fracture of midshaft of clavicle with either anterior or posterior
subluxation/dislocation of SC joint (uncommon)
65. Secondary osteoarthritis
• late complication
• usually be managed conservatively,
• If pain is marked, the outer 2 cm of clavicle can be excised.
66. Case
• 30 yrs/ F with history of fall from
scotter sustaining injury to left
shoulder

The O'Brien test may be particularly helpful when attempting to differentiate symptoms of AC joint arthrosis from intra-articular lesions, especially those of the superior glenoid labrum.
In a study of 100 radiographs of normal shoulders, Urist found that
49% of the AC joints were inclined superolateral to inferomedial, with articular surface of clavicle overriding acromion;
27% were vertical
3% were inclined superomedial to inferolateral, with the articular surface of clavicle underriding acromion
21% were incongruent, with clavicle lying either superior or inferior to acromial articular surface.
