Anatomy of the Shoulder
The shoulder joint is a ball and socket joint. A ball at the top of the upper arm bone (humerus) fits neatly into a socket, called the glenoid, which is part of the shoulder blade (scapula). The glenoid is surrounded by a ring of fibrous cartilage called the labrum for stabilization of the shoulder joint. The biceps tendon attaches inside the shoulder joint at the superior labrum of the shoulder joint. It is a long cord-like structure that attaches the biceps muscle to the shoulder and helps to stabilize the joint.
Shoulder Labral Tear
Traumatic injury to the shoulder or overuse of the shoulder (throwing, weightlifting) may cause the labrum to tear. In addition, aging may weaken the labrum leading to injury.
Symptoms of Shoulder Labral Tear
Shoulder labral tears may cause symptoms such as:
- Catching or locking sensation
- Decreased range of motion
- Joint instability
Treatments for Shoulder Labral Tear
Your doctor may initially suggest conservative approaches such as prescribing anti-inflammatory medications and advise rest to relieve symptoms until diagnostic scans are performed. Rehabilitation exercises may be recommended to strengthen the rotator cuff muscles. In addition, your doctor may discuss ultrasound guided injectable treatment options. If the symptoms do not resolve with these conservative measures, your doctor may recommend arthroscopic surgery.
