Shoulder Injuries
The shoulder's relative lack of supporting structures combined with large external moment arms leads to high rates of injury.
Types of injuries include: fractures, tears, separations, dislocations, "frozen shoulder", and impingements.

Fractures
The clavicle is one of the most commonly fractured bones. Common causes include, sports impacts, falls, auto and accidents. Humeral fractures are classified by the location of the fracture on the humerus and include risk of nerve damage. Scapular fractures are uncommon but causes include auto accidents, and crushing accidents. Tear Labral Tear The glenoid labrum provides a concave surface for the rounded humeral head to articulate. This increases the stability of the joint, but is the subject of occasional injurious tears. The fibrocartilaginous tissue is commonly torn by falls, or accidents. MORE INFO Rotator Cuff Tear Rotator cuff tears pertain to tears of any of the four rotator cuff muscles (supraspinatus, infraspinatus, teres minor, subscapularis). Injuries are commonly a result of sudden movements that may include high impulse or force. Rotator cuff tears cause pain, tenderness, and loss of ROM. MORE INFO Separation Separations are also known as acromioclavicular separation. Separations usually occur due to an impact from above the acromion that Damages the conoid, trapezoid, and/or acromioclavicular ligaments. Dislocation Dislocation occurs when the humeral head "pops out" of the glenoid labrum. The injury is usually externally visible, with the shoulder looking "droopy" or deformed. Occurrence is immediately painful. Dislocation can occur in a variety of directions with anterior dislocation being about 95% of cases. MORE INFO Frozen Shoulder Frozen shoulder, formally adhesive capsulitis, occurs when the tissue surrounding the glenohumeral joint is inflamed and stiffened. This leads to the restricted motion or "freezing" of the shoulder. Pain is also a major symptom and complaint of the condition. MORE INFO Impingement In the most simple terms impingement is a pinching of tissue. This can be related to the rotator cuff muscles within the subacromial space, or more generally tendons or bursa. Tissues can become inflamed from overuse, trauma, or bone spurs. MORE INFO |
