What It Is

Doctors can now use a tiny camera, inserted through a small cut (keyhole surgery, called arthroscopy), to see inside the shoulder joint. This helps them to identify and treat injuries known as shoulder labral tears (AAOS, n.d.a).

Shoulder Labral Tear Anatomy

The shoulder is a ball and socket joint. Around the edge of the socket is a labrum, a rim of tough, cartilage-like tissue. The purpose of the labrum is to make the socket deeper (by up to 50%), which helps to hold the ball in the joint and makes the shoulder more stable. It is also an attachment point for ligaments that help keep the shoulder stable and for one of the tendons of the biceps muscle (AAOS, n.d.a).

Causes of Labral Tear

Labral tears can be caused by a sudden injury or by repeated shoulder movements (AAOS, n.d.a). Examples of injuries include falling on an outstretched arm, a direct blow to the shoulder, a sudden pull such as when trying to lift a heavy object or having your arm wrenched, and a violent overhead reach, such as when trying to stop a fall (AAOS, n.d.a). Impact sports like rugby, football and hockey can involve these kinds of injuries. Repeated overhead movements are a common cause in throwing athletes and weightlifters (AAOS, n.d.a), so throwing sports, tennis, cricket and other overhead sports can also lead to labral tears.

A common cause of labral tears is shoulder dislocation. As the shoulder dislocates, the labrum can be pulled off the rim of the socket (The Dudley Group NHS Foundation Trust, 2025; AAOS, n.d.a).

Labral tears can also develop through normal wear and tear of the joint, along with arthritis (AAOS, n.d.a).

How do I Know if I have a Labral Tear?

Some people remember a specific injury, but many labral tears come on gradually from repeated overhead use or wear and tear (AAOS, n.d.a). The symptoms can be similar to other shoulder problems and may include (AAOS, n.d.a):

  • A feeling that the shoulder is unstable, or the shoulder dislocating
  • Deep shoulder pain, usually with overhead or reaching activities
  • Catching, locking, popping or grinding in the shoulder
  • Occasional pain at night or with daily activities
  • Reduced movement and loss of strength

Some people find their movement comes back after an injury, but months later they still have a low-grade shoulder pain on certain movements, or repeated clicking. This could be a sign of a labral tear.

How is a Shoulder Labral Tear Diagnosed?

A shoulder labral tear is usually diagnosed from the case history and a physical examination (The Dudley Group NHS Foundation Trust, 2025; AAOS, n.d.a). There are some special shoulder tests which can point towards a possible labral tear, but these are not foolproof.

If a labral tear is suspected, the doctor might request an MRI scan, which is the best type of scan for showing soft tissues like the labrum (AAOS, n.d.a). Sometimes a special MRI scan called an MRI arthrogram (MRA) is needed, where dye is injected into the joint before the scan to help show the labrum and any tear (AAOS, n.d.b; The Dudley Group NHS Foundation Trust, 2025).
