Shoulder (subacromial) impingement

None of the above – Shoulder (subacromial) impingement

Intro: Shoulder/subacromial impingement is a common cause of shoulder which results from compression of rotator cuff tendons as it passes underneath the bony tip of the outer edge of the shoulder blade (acromion). This condition causes pain due to irritation of the rotator cuff tendons and the subacromial bursa, a synovial cavity between the acromion and tendons.

Symptoms: Pain on overhead activities and sleeping on the side.

Treatment: Physical therapy and medications. A steroid injection into the subacromial space may provide relief. Plasma rich platelet (PRP) injection, which promotes healing of the tendon, is another treatment modality for this condition. In rare unresolving cases, subacromial decompression surgery can be done, which widens the space where the tendons pass through.
