Abstract

COELHO, Thiago D. Gonçalves. Isolated and painless (?) atrophy of the infraspinatus muscle: left handed versus right handed volleyball players. Arq. Neuro-Psiquiatr. [online]. 1994, vol.52, n.4, pp.539-544. ISSN 0004-282X.  https://doi.org/10.1590/S0004-282X1994000400014.

The suprascapular nerve originates from the upper trunk of the brachial plexus or less frequently from the root of C5. It runs a short way and crosses the suprascapular notch. It innervates the supraspinatus muscle and the acromioclavicular and glenohumeral joints. Then, it crosses the lateral edge of the spine of the scapula passing through the spinoglenoid notch, and innervates the infraspinatus muscle. These are potential sites of injury to the suprascapular nerve. Three cases of suprascapular nerve entrapment causing an isolated infraspinatus muscle atrophy in volleyball players were studied. It is suggested the hypothesis that the nature of the smash, in which the athlete uses the arm violently, more than does in volleyball service or in the art of reception, is the key to the pathogenesis of the lesion in volleyball players.

Keywords : volleyball; infraspinatus muscle; suprascapular nerve; entrapment neuropathy; muscular atrophy.
