The prevalence of infraspinatus muscle atrophy in professional beach volleyball players is 30%. The typical, fully competitive player has subjectively unrecognized decreased strength of external rotation and frequent unspecific shoulder pain. Therefore, abnormal clinical and imaging findings in the beach volleyball player should be interpreted with care.

Professional beach volleyball players have a high frequency of infraspinatus atrophy (34%) and significantly reduced shoulder strength of the hitting shoulder. These findings are not associated with demographic factors. Electromyography and NCV measurements suggest a suprascapular nerve involvement caused by repetitive strain injuries of the nerve. External rotation strength measurements and NCV measurements can detect a side-to-side difference early, while EMG may show compensation mechanisms for progressive damaging of the suprascapular nerve and, as a result, loss of infraspinatus muscle strength.

The purpose of this retrospective study was to analyse the complications of our arthroscopic procedures at the ankle joint. In all patients we evaluated the treatment protocols and in 111 patients (79.3%) we also evaluated the clinical and radiologic results. All in all we have found complications in 14 patients. In 4 cases we have seen a delayed wound healing, in 2 cases a superficial infection, in 3 cases a deep infection, in 3 cases a neural damage and in 2 cases a phlebothrombosis. Our study show, that the complication rate could be minimized by detailed knowledge of the anatomy, exact preoperative diagnostic and planing of the operation and careful preparation of the portals. The use of a laser also shows a tendency to a lower complication rate.
