FAQs: Shoulder - Labral Lesions
Why does my shoulder joint pop, crack and click?
noises in the joints, such as popping, cracking or clicking, can be quite disturbing and cause concern. often, these noises are not indicative of any underlying problem. such noise often persists for years without any real problem developing.
if there is no pain with cracks or clicks, you can assume it is being caused by the soft tissue in a joint.
noises that are associated with pain may indicate damage to the surfaces of the joint. such cracks and clicks may be due to tears in labrum (see shoulder anatomy), which may snap over the other structures as the arm moves.
if the labral tear is at the top of the shoulder it is called a slap lesion. sometimes the clicking may be due to the shoulder slipping in and out of joint. this is known as shoulder instability (subclinical).
