Arthroscopic Subacromial Decompression

Arthroscopic Subacromial Decompression

Subacromial Decompression is a surgical procedure to cure shoulder pain due to inflammation within the shoulder joint. These symptoms are known as “subacromial impingement syndrome” and occur when there is inflammation of the rotator cuff tendons and the bursa which surrounds these tendons. This often results in pain, weakness and limited mobility and flexibility in the shoulder joint.

Symptoms of impingement syndrome:

  • Pain during activities when lifting your arm above head height
  • Shoulder Pain that prevents your from sleeping or wakes you at night
  • Pain on the outside of your shoulder or upper arm
  • Shoulder injury from sports or other physical activity that doesn’t heal on its own
  • General weakness in the shoulder
  • Loss of full range of motion at the shoulder


Subacromial Decompression Causes:

Impingement occurs when the rotator cuff tendon and bursa is squeezed or pinched between the undersurface of the acromiom and the humeral head. (top surface of the arm bone) Typical causes of this pinching include:

  • inflammation of the tendons of the rotator cuff or bursa (often from an initial injury)
  • Bone shape/structure that provides less room for the the tendons to glide freely
  • Bony projections on the acromion ( Subacromial Spurs )
  • Osteoarthritic spurs on the acromioclavicular joint
  • Calcification or thickening of the coracoacromial ligament
