What is a labrum and how can it tear?
The labrum is a stiff cartilage ring that rests around your glenoid, the shallow socket that holds the top of your upper arm bone (humerus). It serves several functions, such as stabilizing the shoulder joint and holding other key ligaments, such as the biceps tendon, in place.
Trauma can tear the labrum either partially or completely. When this occurs, the ball of the humerus can slide part way out of the socket (subluxation) or completely out (dislocation).
How many kinds of labral tears are there?
Complete tears usually arise from injury, such as a dislocated shoulder. The labrum can also experience internal tears. This condition is associated with aging and may not cause symptoms. Another type of labrum tear occurs where the biceps tendon joins the top (superior) side of the shoulder socket. This is known as a SLAP lesion (superior, labrum anterior and posterior).
How is a torn labrum diagnosed?
Because this structure is complex and there are several types of shoulder labrum tears, diagnosing it may include x-rays, magnetic resonance imaging (MRI), and arthroscopic surgery to see inside the joint. Our orthopedic surgeons have deep experience in the diagnosis and treatment of labral tears.
How are labrum tears treated?
Treatment for a torn shoulder labrum varies with the type and severity of the injury. The cartilage can be reattached or trimmed using different types of surgical techniques.
