Labrum Tears In The Shoulder
|
 |
-
The labrum is the cartilage in joints of the shoulders. This is a rim of soft fibrous tissue that surrounds the glenoid (a part of the shoulder blade that makes up the socket of the shoulder joint). The labrum has two functions: First, the Labrum makes the socket of the shoulder joint (glenoid) much larger and deeper, increasing the stability of the joint. Secondly, it is the attachment area of the ligaments around the shoulder joint. Labrum tears may cause similar symptoms to the other shoulder lesions, so it is difficult problem to diagnose.

- Shoulder pain
- Catching sensation
- Limited range of motion
- Shoulder weakness

The causes of labrum tears are usually acute traumas or repetitive activities that cause stress in the shoulder. Unstable shoulders can cause the labrum tears by the free movements of the arm bones (humerus) on the glenoid.

- History and physical examinations to test the stability of the shoulder, its range of motion, strength and pain.
- Shoulder X-Rays rule out other reasons and diagnose underlying problems
- CT or MRI scan of the shoulders detect labrum tears
- A shoulder Arthroscopy confirms the labrum tears by looking into the joint of the shoulder

Conservative treatments include:
- Rehabilitation programs -- strengthening of the shoulder muscles through exercise
- Range of motion in the exercise routine
- Anti-inflammatory medications to relieve pain
- Surgical repair or removal of torn labrum -- if the conservative treatment fails or there is large tear of labrum, surgery is recommended. A torn labrum can be removed or repaired using Arthroscopy.
