The Rotator Cuff:
The rotator cuff is a group of four muscles and tendons that surround the
glenohumeral joint. A muscle contracts to move bones; the tendons are the
attachment of the muscle to the bone. The rotator cuff muscles are important
in movements of the ball-and-socket shoulder joint.
The rotator cuff is important in many routine activities, and when injured
can cause severe pain. When the rotator cuff is inflamed or irritated, this
is referred to as rotator cuff tendonitis or shoulder bursitis. When the
tendons of the rotator cuff have torn, this is called a rotator cuff tear.
The Shoulder Capsule:
The shoulder capsule surrounds the ball-and-socket part of the shoulder
joint. The capsule separates the joint from the rest of the body, and
contains the joint fluid. Several ligaments make up parts of the joint
capsule, and these ligaments are important in keeping the shoulder joint in
proper position. When the shoulder dislocates, the ligaments of the shoulder
capsule can be torn.
The tension of the shoulder capsule is important. If the capsule is too
loose, the condition is called multidirectional instability. When the
shoulder capsule is too tight, the condition is called a frozen shoulder.
The Shoulder Labrum:
The labrum is a rim of cartilage that surrounds the socket of the shoulder
joint. The socket of the should joint is shallow, and the labrum gives the
socket more depth, and thus more stability. The labrum also serves as the
attachment of a major tendon in the shoulder, the biceps tendon.
Labral tears in the shoulder can cause pain, instability of the joint, or
both. Labral tears are usually classified based on their location. The most
common labral tears are those associated with a shoulder dislocation, called
a Bankart tear, and those associated with biceps tendon problems, called SLAP
tears.
