Suprascapular Neuropathy J Am Acad Orthop Surg 7:358-367, Romeo, A.A.,et al, 1999 See this aricle in Pubmed Article Abstract Supracapular neuropathy is an uncommon cause of shoulder pain and weakness and therefore may be overlooked as an etiologic factor. The supracapular nerve is vulnerable to compression at the suprascapular neuropathy include traction injury at the level of the transverse scapular ligament or the spinoglenoid ligament and direct trauma to the nerve. Sports involving overhead motion, such as tennis, swimming, and weight lifting, may result in traction injury to the supracapular nerve, leading to dysfunction. The diagnosis of supracapular neuropathy is based on clinical findings and abnormal electrodiagnostic test results, after the exclusion of other causes of shoulder pain and weakness. Magnetic resonance imaging may provide an anatomic demonstration of nerve entrapment and muscle atrophy.
