BankartLäsion

A Bankart lesion is an injury to the labrum of the shoulder, specifically the anterior-inferior aspect. The labrum is a ring of cartilage that lines the rim of the shoulder socket, deepening it and providing stability to the glenohumeral joint. A Bankart lesion typically occurs when the shoulder dislocates, particularly anteriorly. During an anterior dislocation, the humeral head is forced forward, which can tear the labrum away from the glenoid rim.

The most common symptom of a Bankart lesion is recurrent shoulder instability. Patients may experience feelings of apprehension, looseness, or even repeated dislocations. Pain, clicking, or popping sensations in the shoulder can also be present. The severity of the lesion can vary, from a small tear to a complete detachment of the labrum. Diagnosis is usually made through a physical examination and confirmed with imaging studies such as an MRI or MR arthrogram, which can visualize the labral tear.

Treatment for a Bankart lesion depends on the severity of the tear and the degree of instability. Non-surgical management may be attempted for smaller tears or less severe instability and can include rest, physical therapy to strengthen the rotator cuff and scapular muscles, and activity modification. However, for larger tears or significant recurrent dislocations, surgical intervention is often recommended. Arthroscopic surgery is commonly used to repair the torn labrum by reattaching it to the glenoid rim. The goal of treatment is to restore shoulder stability and function and prevent further dislocations.
