Describe The Role Of The Labrum In The Shoulder

The shoulder is a key attribute to the performance of athletes in all sports. As the shoulder is ball and socket joint, ROM plays a huge role in the ability of the shoulder. The Labrum in the shoulder is the fibrocartilage that is attached to the rim of the socket which keeps the ball of the joint in place (Hopkins Medicine, n.d.). The labrum is key to the stability of the shoulder. A torn labrum occurs when the cartilage that is attached to the rim ruptures. The labrum can tear a few different ways; first is when the labrum is torn completely off the bone, this is usually associated with a dislocation and subluxation; second is within or along the edge of the labrum, this type of tear is quite common and rarely causes symptoms and is usually
The bones that are in the shoulder are the Humerus which is the upper arm bone, Scapular which is the shoulder blade, and the Clavicle which is the collar bone. The top of the shoulder is formed by the acromion which is part of the scapular. There are four joints in the shoulder. The first is the glenohumeral joint, which is where the head of the humerus bone fits into the socket of the scapula. The acromioclavicular joint (AC) is where the clavicle meets the acromion. The Sternoclavicular joint supports the arm and shoulder connection to the front of the chest. A false joint is formed where the shoulder blade glides against the thorax (the rib cage). This joint, called the scapulothoracic joint, is important because it requires that the muscles surrounding the shoulder blade work together to keep the socket lined up during shoulder movements. The three tendons in the shoulder are the supraspinatus tendon, the infraspinatus tendon, and the teres minor tendon. The superficial muscles of the shoulder are the deltoid, parts of the trapezius and latissimus dorsi. A couple deep muscles of the shoulder are the minor and major rhomboids (Houston Methodist Leading
For most patience of a torn labrum, immobilization of shoulder for 4-6 weeks with the arm in a sling is required as the patient tries to gain feeling and stability in the shoulder. During these four weeks, the patient will have passive, pain-free ROM exercises. Nothing that is stress and weight barring on the shoulder until out of a sling. No apparent structural damage is evident from surgery except that if athlete rushes through rehab and does not the strengthen shoulder, then the shoulder can dislocate and tear the Labrum again. In a study that looked at a new anatomic technique for type two lesions repair, fourteen patients were selected which had a torn labrum. A visual analogic scale, ROWE, UCLA, ASES and Constant scores were used to make an evaluation. The passive ROM before surgery, at final follow-up, and the resumption of sports activities were analyzed. “the Constant, ASES, UCLA and ROWE scores passed from 64.6 (SD 13.9), 76.9 (SD 22.4), 28.4 (SD 23.8) and 53.6 (SD 20.6) to, respectively, 92.6 (SD 11.8), 108.3 (SD 8.5), 33.6 (SD 2.7) and 96.5 (SD 7.2) at final follow-up. Of the four patients who had participated in agonistic overhead athletics preoperatively, all of them were able to return to their preinjury level. No complications were observed in the present study” (Castagna, eta,
