Revision open capsular shift for atraumatic and multidirectional instability of the shoulder.

Shoulder stability is critical for proper functioning of the upper extremity and is dependent on the interplay between static and dynamic stabilizers of the glenohumeral joint. Surgical management of patients with atraumatic and multidirectional instability is effective if the capsular redundancy is properly reconstructed to restore glenohumeral joint biomechanics. Residual capsular laxity is a common cause of recurrent glenohumeral joint dislocation in patients who had previous stabilization procedures; surgical results become less predictable in patients who had multiple revision procedures. It is important to detect capsular laxity at the time of the index surgery and use reliable surgical techniques to obtain optimal results.
