The labrum is the fibrous rim around the shoulder socket. A tear can cause pain, catching or popping, and a sense that the shoulder may give way.
The labrum is a rim of strong fibrous tissue around the edge of the shoulder socket. It deepens the socket by roughly half, helps hold the joint stable, and anchors several shoulder ligaments as well as the long head of the biceps tendon. Tears are described by where they sit — SLAP tears at the top where the biceps attaches, Bankart lesions at the front-lower socket after a dislocation, and posterior tears at the back. They follow either a distinct injury — a fall onto an outstretched arm, a forceful pull or overhead reach, or a dislocation — or gradual wear from repeated overhead activity.
Assessment focuses on the history and a careful examination of shoulder movement, strength and stability, using positional tests to reproduce symptoms. The neck is checked too, since a pinched nerve there can mimic shoulder pain. X-rays do not show the labrum but exclude arthritis and fracture. MRI shows the soft tissue far better, and an MR arthrogram — contrast injected into the joint before the scan — is sometimes needed. Because labral fraying is common in shoulders that do not hurt from middle age onward, imaging is most useful when the result will change what happens next.
First-line care is usually non-surgical: settling the pain with simple analgesia or a short course of anti-inflammatory medication, modifying aggravating overhead load, and a physiotherapy program restoring capsule flexibility and rotator cuff strength — typically over three to six months. Surgery, most often arthroscopic, is considered when pain persists despite that program or when the shoulder is unstable, and involves either trimming the torn tissue, repairing it with sutures, or addressing the biceps attachment. Recovery after surgery is gradual, with a sling for two to six weeks and sport-specific work usually from around three months.
