» Request a referral to a John C. Lincoln labrum surgeon in Phoenix
The shoulder is often referred to as a "ball-and-socket" joint. The head of the humerus (upper arm bone) fits into an area of the shoulder blade called the glenoid socket.
The glenoid socket is not very deep — it may cover only one-third of the humeral head. The remainder of the socket is shaped by a circular rim of soft, fibrous tissue, called the labrum.
When the labrum becomes detached from the glenoid — due to trauma or repetitive movement — the humerus can slip out of the glenoid socket, requiring labrum surgery.
Labrum repair involves reattaching the labrum to the glenoid cavity by implanting anchors into the bone and affixing the labrum in place with sutures.
The orthopedics departments of John C. Lincoln Hospitals invite you to watch this overview of labrum surgery.
