Study Notes

Shoulder Anatomy and Joints

Glenohumeral joint: Shallow ball and socket joint with a high range of motion, surrounded by the labrum for stability.
Acromioclavicular joint: Limited movements governed by acromioclavicular and coracoclavicular ligaments, essential for shoulder stability.
Sternoclavicular joint: Exhibits minimal movement; injuries are infrequent.
Scapulothoracic joint: Functions as a gliding joint, crucial for arm rotation during throwing activities.

Glenohumeral Joint Stability

Stability hinges on the capsulolabral complex and integrated muscular functions, especially from the rotator cuff.
Anterior glenohumeral ligaments (superior, middle, inferior) and surrounding ligaments (coracoacromial, coracohumeral) enhance stability.

Common Injuries in Throwing Sports

Common in athletes participating in baseball, tennis, volleyball, javelin, water polo, and swimming due to repetitive shoulder motions.
Loss of internal rotation, buildup of posterior capsular tightness, and potential scarring can occur from repetitive activity.

Impingement and Pathology

Posterior capsular tightness can cause posterosuperior impingement, leading to SLAP (Superior Labrum Anterior to Posterior) lesions and rotator cuff degeneration.
Anterior capsule stretching can overload the rotator cuff, leading to cuff dysfunction and SLAP lesions, worsened by scapular dyskinesia and acromion shape.

Diagnostic Evaluation

Diagnosis relies on comprehensive clinical history, muscle inspection, range of motion assessment, and special tests for impingement (Hawkin’s, Neer signs) and biceps tendon evaluation (Speed test, Yergesson test).
Imaging (X-ray, MRI) is critical for identifying bony lesions, assessing cuff tears, and observing labral detachment.

Management Approaches

Conservative management is typically recommended for Grade I and II AC joint injuries, while surgical intervention is necessary for Grades IV and above.
Rehabilitation focuses on restoring strength, range of motion, and biomechanics; passive movements should be initiated early post-surgery to prevent stiffness.

Surgical Options for Shoulder Stability

Surgical repair often involves arthroscopic techniques to reattach the labrum to the glenoid using anchors, addressing other lesions like capsular laxity.
The open Latarjet procedure may be chosen for recurrent dislocations, severe instability, and substantial bony injuries.

Glenohumeral Internal Rotation Deficit (GIRD)

GIRD reflects a loss of internal rotation range due to anterior capsule stretching, correlating with instability and repeated throwing motions.
Causes of injury include anterior capsule overstretching and secondary impingement, aggravated by muscle weakness, particularly in the periscapular region.

Scapular Dyskinesia and Acromion Types

Scapular dyskinesia leads to improper scapular motion, which critically affects shoulder function in overhead movements.
Acromion types vary (flat, curved, hooked), with the hooked type presenting the greatest risk for impingement and associated injuries.

Summary of Throwing Phases

Multiple phases contribute to shoulder injuries, including stance, wind-up, cocking, acceleration, and follow-through, with the cocking phase being the most injurious.

Overall Implications

Athletes should undergo regular assessments to identify early signs of injury, with an emphasis on preventive strategies to maintain shoulder health and performance.### Shoulder Joint Anatomy and Physiology
The shoulder girdle includes the glenohumeral, acromioclavicular, sternoclavicular, scapulothoracic, and intercostal joints.
Glenohumeral joint: A shallow ball-and-socket joint offering the widest range of motion, but prone to instability due to its structure.
Stability of the glenohumeral joint relies on the capsulolabral complex and the centering action of the rotator cuff.
Acromioclavicular joint allows minimal movements, mainly during extreme shoulder motions, stabilized by strong ligaments.
Sternoclavicular joint has minimal movement and significance, with rare injuries.
Scapulothoracic joint facilitates arm rotation above shoulder level, crucial for throwing sports.

Painful Throwing Shoulder

Commonly seen in athletes from baseball, tennis, volleyball, javelin throwing, and swimming due to repetitive shoulder movement.
Clinical signs include loss of internal rotation range due to posterior capsular tightness, potentially leading to impingement and SLAP lesions.
Anterior capsule stretching may result in cuff overload, internal impingement, and subsequent instability.

Mechanisms of Injury

Repeated throwing creates stability issues by stretching anterior capsule ligaments while overloading the rotator cuff.
Posterior tightness can lead to internal impingement and further deterioration of shoulder stability.

Diagnosis and Management

Diagnosis primarily involves a thorough clinical history and specific physical tests (e.g., Hawkins, Neer, apprehension tests).
Imaging techniques:
- X-rays exclude bony lesions and confirm arthritis.
- MRI detects cuff lesions and other soft tissue injuries.
Management includes conservative rehabilitation focusing on muscle strengthening and flexibility, with surgery as a last resort for severe cases.

Shoulder Instability

Most common type is anteroinferior instability, occurring from forced abduction and external rotation.
Recurrent dislocations may arise, typically due to underlying structural issues like Bankart lesions or Hill-Sach lesions.

AC Joint Injuries

Caused mainly by falls impacting the shoulder; common in contact sports such as rugby.
Management varies by severity: grades I and II treated conservatively, while grades IV, V, and VI may require surgical intervention.

Posterior Cruciate Ligament (PCL)

PCL is the main stabilizer of the knee, often sustaining injuries alongside other ligaments.
PCL injuries commonly occur due to stress or varus forces, particularly in contact sports.
Diagnostic imaging (MRI) is crucial for identifying associated injuries.

Biomechanics and Management of Ligament Injuries

The PCL controls posterior displacement of the tibia; affected by varying degrees of knee flexion.
Management of combined ligament tears suggests reconstructive surgery during one session to prevent overstressing.
Clinical assessments for ligament injuries should focus on understanding the nature of the injury (contact vs. non-contact) and accompanying symptomatology.

Rehabilitation Post-Surgery

Emphasizes gradual recovery with early passive movements to prevent stiffness while regaining motion and strength.### Medial Collateral Ligament (MCL) Anatomy
The MCL consists of medial capsular, posterior oblique, meniscofemoral, and meniscotibial parts, extending from the medial femoral condyle to the tibial plateau.
The superficial ligament is the largest medial structure (10-12cm long, 1.5cm wide), attaching proximal to the medial epicondyle and inserting at the medial proximal tibia.

Biomechanics

The MCL is the primary restraint to valgus stress at 5-25 degrees of knee flexion.
Anterior and posterior fibers work independently depending on knee flexion, with the MCL mostly engaged during full extension.

Classification of MCL Injuries

Grade I: History and tenderness on the medial side with minimal joint line opening; may test negative on valgus stress.
Grade II: Similar to Grade I with joint line opening but an endpoint present.
Grade III: Continuous joint line opening without an endpoint; often termed "open book."

Clinical Presentation

Commonly injured ligament in the knee with a history of valgus stress injury.
Pain and tenderness located medially, especially at the medial epicondyle or proximal tibia.
Valgus stress test is performed in full extension and at 30 degrees of flexion; minimal swelling may occur.

Diagnosis

MRI is the preferred diagnostic tool, revealing irregularities and edema at the medial knee; it can also identify associated injuries.
Radiological assessments may also include X-rays to check for bony instability or avulsions.

Management Strategies

Conservative treatment is recommended for Grade I and II tears, including hinge knee braces and physical therapy to encourage healing over 6-8 weeks.
Surgical intervention for Grade III tears involving continuous opening during stress tests or visible avulsion fractures.

Rehabilitation

Early post-operative rehabilitation begins immediately to maintain muscle activity and prevent stiffness.
Focus on regaining knee extension, range of motion, proprioception, and strength, following a timeline of about 6 months under strict supervision.

Posterolateral Corner Anatomy

Complex structure consisting of static (lateral collateral ligament, posterolateral capsule) and dynamic components (iliotibial band, popliteus, etc.).
Fractures of the fibula can significantly impact stability in the posterolateral corner.

Surgical Management of Ligament Injuries

For ACL injuries, surgical treatment is often necessary, while for MCL, conservative management suffices unless damage is severe.
The posterolateral complex often requires surgical intervention due to limited healing potential.

Posterior Cruciate Ligament (PCL) Anatomy

The thickest knee ligament, primarily stabilizing the knee, originating from the medial condyle and inserting into the tibia.
PCL injuries are often treatable conservatively, depending on the extent and type of injury.

Elbow Rehabilitation

Early active mobilization is critical in preventing stiffness due to the sensitive nature of the elbow joint.
Emphasis on training within pain limits and encouraging active movements for effective rehab.

Sports Injury Prevention

General measures include warming up, proper training loads, protective gear, and health exams.
Specific prevention techniques target common injuries such as ACL and hamstring strains.

AC Joint Injuries

Most commonly occur from falling on the shoulder, prevalent in contact sports.
Management varies, with conservative approaches for Grade I and II, and surgical options for higher grades (IV, V, and VI).
