Shoulder impingement syndrome causes limitation of shoulder movements in one or more directions, but never complete global loss of movements.
Also known as a "Painful arc syndrome"; when the arm is taken overhead in the window cleaning position, patient catches pain. Pain is reproduced on every attempt to do this manoeuvre.
The patholy lies in the reduction of space for the free excursion of the rotator cuff tendons mainly Supraspinatus, beneath the acromion process.
This may occur due to inflammation of tendon itself, due to thickening of acromion process of shoulder blade (scapula); or due to repetitive stress injuries of the rotator cuff.
Treatment of this disorder is mostly conservative.
Most patients respond to suitable modification of activity or local steroid infiltration.
In patients who are resistant to conservative trials, decompression of the sub-acromial space may be performed surgically (Acromioplasty).
