One patient underwent operation bilaterally within 5 years. Five patients presented with a history of trauma to the shoulder region. In three patients, a ganglion cyst was the origin of the nerve lesion. In 16 patients, the nerve problem was primarily related to athletic activities. Eight of these patients were professional volleyball players. In the remaining three patients, there was no relationship between the nerve lesion and trauma or athletic activities.<\/jats:p><jats:p content-type=\"fine-print\">Twenty-one patients (22 cases) complained of pain located over the suprascapular notch. Seventeen patients had paresis and atrophy of both the supraspinatus (SS) and infraspinatus (IS) muscles. In 10 patients only the IS muscle was involved. One patient exhibited a sensory deficit over the posterior portion of the shoulder. Electromyography was performed in all cases.<\/jats:p><jats:p content-type=\"fine-print\">The mean follow-up period in the 25 cases (24 patients) that could be evaluated was 20.8 months (range 3\u201370 months). Nineteen of 22 cases with preoperative pain could be evaluated. Sixteen of these patients were completely free of pain after surgery and three patients found their pain had improved. Motor function in the SS muscle improved in 86.7% and motor function in the IS muscle in 70.8% of cases. Atrophy of the SS muscle resolved in 80.7% and atrophy of the IS muscle in 50% of cases.<\/jats:p><jats:p content-type=\"fine-print\">Surgical treatment of SNE is indicated after failed conservative treatment and in cases of atrophy of the SS and IS muscles. The authors recommend the posterior approach, which minimizes risks and complications and produces good postoperative results.<\/jats:p>","DOI":"10.3171\/jns.1996.85.6.1020","type":"journal-article","created":{"date-parts":[[2009,6,8]],"date-time":"2009-06-08T20:37:01Z","timestamp":1244493421000},"page":"1020-1025","source":"Crossref","is-referenced-by-count":123,"title":["Suprascapular
