Impingement Syndrome
Rubbing and clicking of shoulder on overhead motion.
Ball of shoulder rubs against ledge (Acromium) over shoulder. Associated with tendinitis and rotator cuff problems.
i. Treatment
Anti-inflammatory medicine, Cortisone Injection, Surgery to shave Acromium
Dislocation
Ball of shoulder pops out of socket.
Treatment
Reduction - Anesthesia is frequently required, Sling for 3-4 weeks, Exercises, Surgery to repair shoulder after 2nd or 3rd dislocation
Shoulder Separation
Injury to A-C joint; collarbone is displaced from top of
shoulder.
Treatment
Rest and sling, X-rays, Surgery may be necessary if severe
Rotator Cuff Tear
Injury to muscle and tendon that covers and raises shoulder. Symptoms include shoulder pain and inability to raise shoulder
Treatment
1. Rest, Medicine, MRI if no better, Surgery to repair large tear
