Q

what are causes of subacromial impingement syndrome

A

Intrinsic:

  • muscle weakness (rotator cuff weakness > imbalanced forces > humerus rotates)
  • hounder overuse (inflammation > reduced space)
  • degenerative tendinopathy (acromium degeneration > cuff tear)

Extrinsic

  • glenohumeral instabiklity
  • anatomical variation

what are symotoms of rotator cuff tear

A

painful arc (if partial tear)

if complete tear:

  • inability to abduct arm
  • lowering the arm beneath 90 degrees causes a SUDDEN DROP (as this is supraspinatus role, which is torn)
