The tissue known as the labrum aids in maintaining the position of the humerus, the end of the arm bone. The shoulder joint's socket is incredibly shallow and unstable. This indicates that there is inadequate retention of the shoulder bones. As a result, the labrum, a cuff of cartilage in the shoulder joint, creates a cup-like space for the end of the arm bone to slide in.
The labrum encircles the narrow shoulder socket, deepening it. The shoulder joint is substantially more stable and has a very broad range of motion because of this cuff of cartilage.
Due to its dense tissue composition, the labrum is prone to damage from stress to the shoulder joint. If you have injured your shoulder, a labral tear may be the culprit.
Shoulder labral tears can occur from an injury or through a long-term wear and tear. Common causes include the following:
Factors that may increase your chance of a labral tear include:
Participation in certain sports, such as:
Symptoms may include:
You will be asked about your symptoms and medical history. A physical exam will be done.
Imaging tests to evaluate the shoulder and surrounding structures may include:
Treatment options include the following:
This course of treatment is typically tried for several weeks. Surgery is considered if there is no improvement. To relieve pain and inflammation in your shoulder, your doctor may also administer an injection of steroids.
In a shoulder arthroscopy, a doctor makes a tiny incision and inserts a thin, lit tube to inspect and treat the problem. This tube is used to thread small equipment through. The torn tissue or ligament may be stitched back together or removed. Any damaged tendons may also be repaired using threads or anchors.
You will be given a sling to wear for up to 4 weeks following surgery. After the sling is taken off, you will progressively strengthen your arm muscles and improve your range of motion while working with a physical therapist.
