Hill-Sachs Lesions

The most common bony lesion associated with traumatic glenohumeral instability is a compression fracture at the posterolateral margin of the humeral head Commonly known as a Hill-Sachs lesion, this fracture occurs as the humeral head impacts the glenoid edge during dislocation.

The lesion is present in 80% of anterior dislocations, 25% of anterior subluxations, […]

Shoulder Labral Tears and Instability

Key Points

The goal of therapeutic approaches to glenohumeral joint instability is the restoration of anatomy. The glenohumeral joint is inherently unstable, with the large humeral head articulating with the small and shallow glenoid. The labrum acts as the anchor point for the capsuloligamentous structures, increases the depth of the glenoid socket, and facilitates the […]

Shoulder Impingement Syndrome

Basics Description Shoulder pain with overhead activities is a common musculoskeletal complaint. Impingement syndrome: Inflammatory condition of the soft tissues of the subacromial space Most common cause of presentation for shoulder complaints to a physician’s office (>50% of all shoulder complaints) Represents a continuum, progressing from acute bursitis, to chronic bursitis, to partial-thickness tears […]

Rotator Cuff Injuries

Basics Description Comprises 4 musculotendinous structures (the supraspinatus, infraspinatus, teres minor, and subscapularis) that: Compress the humeral head into the glenoid, allowing the larger muscle groups to function properly Provide muscular balance to the glenohumeral joint Injuries to the cuff can occur at any age, but injuries to people >60 years old are likely […]
