Dating at the upper larum
If you have questions about shoulder injuries including labrum tears, please call Jim C.Hsu MD at The Polyclinic Orthopedic Department at 206-860-5578 for expert diagnosis and comprehensive treatment.Treatment of labrum tears typically begins with a conservative approach.Rest, anti-inflammatory medications can often address the immediate pain.Physical therapy can improve biomechanical deficiencies and to lead to long-term pain relief and return to sports and activities.If conservative treatment fails, or if the likelihood of recurrent instability is high—in younger, more active patients for example—surgery may be required.When the labrum is torn, the damage and the loss of attachment to bone can lead to pain, partial instability, and dislocation.A traumatic shoulder dislocation often tears the labrum off bone.
The MRI is typically done with an injection of contrast directly into the joint (arthrogram).
The cartilage of the anterior labrum differs from articular, or connective, cartilage in several ways.
Articular cartilage is found between the bones that comprise a joint, while labrum cartilage is only found around the socket portion of a ball and socket joint.
One of the soft tissue structures, the labrum, is a cartilage rim that runs along the edge of shoulder socket, or glenoid.
The labrum plays an important role in shoulder function: ligaments that stabilize the upper arm or humeral head (ball) against the glenoid (socket) are attached to the labrum, and the long upper biceps tendon starts off at the labrum at the top of the socket.

If the tear fails to heal on its own, it can lead to recurrent shoulder instability.
