Abstract
Compression of suprascapular nerve at the suprascapulr notch or spinoglenoid notch can be a cause of a rare mononeuropathy. Patients complain of pain in scapula and shoulder, and selective wasting and weakness of the supraspinatus and infraspinatus muscles.
Tenderness at the suprascapular notch and pain by forced abduction of arm are typical and useful signs. Electromyographic signs of various grade denervation are regularly found in both muscles.
Development of entrapment syndromes is associated with chronic overload, shoulder injuries, with surgical procedures, or with shoulder-arm fixation. The authors present their own group 10 patients, who were operated on for entrapment syndrome of suprascapular nerve during 7 year period.
Direct or indirect traumatic mechanisms of development of nerve compression were disclosed in most patients.
