Shoulder instability occurs when the head of the humerus moves excessively or dislocates from the shoulder socket. It can result from trauma, repetitive strain, or underlying joint laxity.
The shoulder is a ball-and-socket joint with a wide range of motion, making it inherently prone to instability. The labrum, ligaments, and rotator cuff muscles provide essential support.
Patients may experience pain, a sensation of the shoulder slipping out of place, or recurrent dislocations. Common causes include traumatic injury, ligament laxity, or repetitive overhead motions.
Non-surgical treatments focus on strengthening the shoulder’s stabilising muscles. In severe cases, surgical interventions like labral repair or capsular tightening may be necessary.
Sports involving overhead movements, like swimming or tennis, pose a higher risk.
Many cases improve with targeted physiotherapy and strengthening exercises.
