Shoulder tendon, trapped
Whatcauses shoulder impingement syndrome?
The subacromial space is naturally quite narrow, especially when the arm is raised. Anything that further narrows this space can cause the tendon to become trapped.
Possible causes include:
- bone spurs under the bony roof (acromion) at the top of the subacromial space can narrow the space and catch on the tendon
- swelling or thickening ofthe rotator cuff tendon whichmay result from an injury or general overuse of the shoulder
- inflammation of the fluid-filled sac (bursa) that lies between the rotator cuff tendon and acromion(known as " Knee, housemaid's ")
- a build-up of calcium deposits within the rotator cuff tendon
