A dislocated shoulder is a condition in which the head of the humerus is detached from the glenoid fossa.[2] Symptoms include shoulder pain and instability.[2] Complications may include a Bankart lesion, Hill-Sachs lesion, rotator cuff tear, or injury to the axillary nerve.[1]
A shoulder dislocation often occurs as a result of a fall onto an outstretched arm or onto the shoulder.[3] Diagnosis is typically based on symptoms and confirmed by X-rays.[2] They are classified as anterior, posterior, inferior, and superior with most being anterior.[2][1]
Treatment is by shoulder reduction which may be accomplished by a number of techniques.[1] These include traction-countertraction, external rotation, scapular manipulation, and the Stimson technique.[1] After reduction X-rays are recommended for verification.[1] The arm may then be placed in a sling for a few weeks.[2] Surgery may be recommended in those with recurrent dislocations.[2]
Not all patients require surgery following a shoulder dislocation. There is moderate quality evidence that patients who receive physical therapy after an acute shoulder dislocation will not experience recurrent dislocations.[5] It has been shown that patients who do not receive surgery after a shoulder dislocation do not experience recurrent dislocations within two years of the initial injury.[5]
About 1.7% of people have a shoulder dislocation within their lifetime.[3] In the United States this is about 24 per 100,000 people per year.[1] They make up about half of major joint dislocations seen in emergency departments.[1] Males are affected more often than females.[1] Most shoulder dislocations occur as a result of sports injuries.[5]
