(Purpose)We Studied the diagnosis and surgical management of suprascapular nerve entrapment neuropathy in athletes.(Materials and methods)Eighteen patients with infraspinatus muscle atrophy were studied. Fourteen were men and 4 women. Their mean age was 27 (range 14 to 40) years. The diagnosis was confirmed by physical and electromyographic examinations. As an ancillary test, MRIs of the shoulder joint were obtained. Those patients with rotator cuff tear were excluded from this study.(Results)Electromyographic examinations showed an abnormality in 8 patients. Two of them had isolated paralysis of the infraspinatus muscle. We operated on 4 patients with suprascapular nerve entrapment. We performed a release of the superior scapular transverse ligament on 2 patients with paralysis of the supraspinatus and infraspinatus muscles, a shaving of the spinoglenoid notch on a patient with isolated paralysis of the infraspinatus muscle and removed the ganglion cyst in 1. All the patients had good results, however, they needed 1 or 2 years to recover from paralysis.(Conclusion)Early diagnosis and treatment are important for the management of suprascapular nerve entrapment neuropathy in athletes.
