Labrum Surgery
Advances in medical technology are enabling doctors to identify and treat injuries that went unnoticed 20 years ago. For example, physicians can now use miniaturized television cameras to see inside a joint. With this tool, they have been able to identify and treat a shoulder injury called a glenoid labrum tear.
The shoulder joint has three bones: the shoulder blade (scapula), the collarbone (clavicle), and the upper arm bone (humerus). The head of the upper arm bone (humeral head) rests in a shallow socket in the shoulder blade called the glenoid. The head of the upper arm bone is usually much larger than the socket, and a soft fibrous tissue rim called the labrum surrounds the socket to help stabilize the joint. The rim deepens the socket by up to 50% so that the head of the upper arm bone fits better. In addition, it serves as an attachment site for several ligaments.
Treatments
Surgical
Surgery to repair the torn labrum is sometimes necessary. The purpose of the surgery is to reattach the torn labrum to the socket of the shoulder. Large labral tears that are the result of trauma generally need to be fixed in surgery. The success rate of this surgery is quite good, with over 90 percent of patients returning to their normal activities without any further dislocations. In many cases, this surgery is performed arthroscopically; however, there are some individuals who should have a Bankart (labral) repair performed through an open incision. With a small labral tear, the patient may be directed to avoid vigorous activities that cause shoulder pain, rather than undergo surgery. Your orthopedic surgeon is best qualified to determine which procedure is most suitable.
