thick description look over the shoulder

The portion that attaches in the shoulder actually goes through a small hole in the rotator cuff tendons designed specifically for that tendon. At the other end of the muscle is a large tendon that attaches beyond the elbow in the forearm. While this muscle is quite large, it turns into a small tendon about the size of a pencil that attaches inside the shoulder joint. The biceps muscle is the muscle on the front of the arm which gets firm with bending the elbow. The other structure that attaches to the labrum is the tendon of the biceps muscle. Whether the joint continues to be unstable depends upon many factors. Usually when this happens the labrum does not heal back in the right location. In either case the labrum can be torn off of the bone.

The ball of the shoulder can dislocate toward the front of the shoulder (an anterior dislocation) or it can go out the back of the shoulder (called a posterior dislocation). This injury usually involves a subluxation or dislocation of the shoulder and is usually due to trauma. If there is an injury to the shoulder that tears the ligaments, sometimes the labrum is pulled off of the rim of the bone as well. For example, the ligaments that help hold the joint together attach to the labrum in certain key locations. The second function of the labrum is as an attachment of other structures or tissues around the joint. Only recently have specialists determined which parts are normal and which parts reflect tearing of the labrum. The labrum goes all the way around the socket and in most areas is firmly attached to the bone of the socket. In individuals where the labrum is too small or is torn due to an injury, the ball may slide part of the way out of the socket (subluxation) or all the way out of the socket (dislocation). The labrum is a thick tissue or type of cartilage that is attached to the rim of the socket and essentially forms a bumper that deepens the socket and helps keep the ball in place.

The other way the ball is kept in the socket is the labrum. The ligaments are the tethers that go from bone to bone and hold them together to help keep the ball in the socket. The ball of the humerus (the “beach ball”) is much larger than the flat socket (the “dinner plate”).

Picture the shoulder joint as a beach ball on a dinner plate. The first is to deepen the socket so that the ball stays in place.
