SLAP TEARS

Tears of the Superior Labrum of the Shoulder Joint


The shoulder is a ball and socket joint. The socket is made deeper by having a rim of fibrocartilage than runs around its periphery- this is known as the labrum. The biceps muscle has a tendon, known as the long head of biceps tendon that takes its origin off the superior aspect of the labrum and glenoid.

Normally the labrum is attached securely to the socket. Sometimes the labrum becomes detached. When this occurs at the superior labrum, it tears anteriorly and posteriorly and is known as a SLAP (Superior Labrum Anterior Posterior) Lesion.

Detachments of the superior labrum can be a “normal” finding, usually in an older patient. They can, however cause pain and loss of function in the overhead athlete (e.g. tennis player, baseball pitcher), or in somebody who has sustained a forceful injury to their shoulder.

All patients should initially be managed with non-operative measures which include modification of activities, analgesics, physiotherapy, and sometimes steroid injections. If these measures fail, then surgery may be considered.

Surgery involves repairing the labrum back to the bone. It is best performed arthroscopically (minimally invasive techniques) using a camera through 1 cm wounds. Anchors are put into the bone which have sutures which then secure the labrum to the bone. Sometimes the long head of biceps tendon is also treated by cutting it off the labrum (tenotomy) and then securing it to a different bone (tenodesis).

Surgery is followed by 4-6 weeks in a sling, followed by physiotherapy to regain motion and then strength in the shoulder. Recovery following surgery is approximately 6 months.
