What are the labrum and biceps and what do they do?
When the shoulder joint is injured, the contents of the joint are at risk. The shoulder joint contains the origin of the long head of the biceps tendon, as well as a cartilaginous structure called the labrum. The labrum functions to help stabilize the joint, preventing excessive motion and dislocation when the shoulder is in a vulnerable position. The biceps tendon and labrum are intimately related inasmuch as an injury to one usually causes injury to the other.
