LABRAL TEAR
The Glenoid Labrum is a protective disk of fibrocartilage that surrounds and deepens the cavity of the Glenoid. The labrum allows for full range of motion, stability, and cushioning in the shoulder. It is attached to the edge of the shoulder socket and supports the ball of the joint -or the head of the arm bone, known as the humerus- in order to stay in place. When the fibrocartilage of the labrum is torn, it is considered a labral tear. There are three common labral tears; Posterior labral tears, Superior labral tear from anterior to posterior (SLAP tear), and Bankart tears. While athletes -who play sports with large amounts of shoulder movement, including tennis or baseball- are more prone to labral tears, older adults are too because of their brittle bones. Signs and symptoms of a torn labral consist of “a sharp pop or catching sensation in the shoulder during certain shoulder movements” (Houston Methodist, 2003). This may be followed with an aching pain for several hours after and trouble doing normal shoulder movements. According to the Myers Sports Medicine & Orthopedic Center, patients often say that “the pain is located at the back on top of the shoulder or in the front on top of the shoulder, the pain feels like it is deep inside, [and] palpation on the shoulder does not duplicate the pain that they have.” Posterior labral tear symptoms include pain and tenderness to the shoulder, instability, and popping sounds with range of motion. SLAP tear symptoms are usually painful to the biceps tendon, a deep pain in the shoulder, and weakness or pain in activities that involves overhead movements and inward rotation. The most common way that labral tears occur are when there’s trauma to the shoulder. This includes falling on an outstretched arm, forcefully lifting an object, wearing and tearing because the body becomes frail as people age, continuous throwing, and overuse of the shoulder. For baseball players, pitching can cause the labrum to tear because of the amount of stress used to pitch a ball. 3 LABRAL TEAR This is the same for tennis players, weightlifters, and golfers, because of the amount of overhead positions these athletes do. The labrum can be torn in three different ways; it can be torn completely off the bone, along the edge of the labrum, and where the bicep tendon connects. The anatomy of the shoulder consists of three bones; The scapula also known as the shoulder blade, the humerus also known as upper arm bone, and the clavicle also known as the collarbone. These bones and connected by ligaments, which is the tissue that holds the bones together. The …show more content…
Tears that are larger may need an open procedure. Using an MRI to diagnosis a torn labrum is not as accurate as arthroscopy.
