Sometimes an injury can cause the humeral
head (top of the arm bone) to come out of glenoid (the socket).
Most shoulder dislocations are anterior dislocations meaning the humeral head comes forward as
it leaves the socket. The labrum is a rim of cartilage that attaches
around the edge of the glenoid and contributes to the stability of the shoulder joint. Sometimes
the humeral head tears part of the labrum as it dislocates. This is known as a Bankart
lesion. The Bankart lesion can result in the shoulder joint becoming unstable and requiring
surgery. A Bankart repair involves reattachment and tightening of the torn labrum.
The torn edges of the labrum are removed to reveal fresh labrum.
Small holes are drilled in the glenoid to receive a special fixation device called an
anchor. Attached to the anchor are sutures which are used to pull the labrum back on
to the glenoid. This process is repeated until the labrum
is completely reattached to the glenoid. After the procedure the arm is placed in a
sling for a few weeks. Physical therapy will be required to regain shoulder motion and
