Disorders of the rotator interval: Coracohumeral ligament and biceps tendon

Abstract

From the time Neer first described the anatomy of the rotator interval in 1970, our understanding of the biomechanical role of its contributing structures has continued to evolve. This is in part due to a better understanding of the disability recognized in rotator interval pathology. Multiple studies have demonstrated the contribution of the rotator interval to humeral head translation and overall stability of the shoulder. Contractures are typically treated nonsurgically, whereas laxity is often combined with anterior-interior instability and may warrant possible surgical intervention. Surgical options, mainly for those with long head of biceps tendon related parts, are described.
