[Isolated rupture of the subscapularis tendon in the overhead athlete - the result of chronical overuse?].

The case of a 27-year-old overhead athlete with chronic shoulder pain because of an isolated subscapularis tear without trauma is described. Arthroscopy has proven to be the appropriate method for detailed visualisation of the injury and facilitates the operative planning. Furthermore, arthroscopy closes the problem of a "diagnostic gap". In the presented case, the results at the two year follow-up are excellent. The authors conclude that an operative approach is also justified in non-traumatic isolated ruptures of the subscapularis muscle.
