Schmerzhafte Ansatzanomalie des M. palmaris longus bei einem Konzert-Cellisten

: A professional cellist suffered four years from pain and fatigue of unknown etiology to his right thumb while playing his cello. These complaints in his performing right hand were potentially threatening his future career, since he was no longer able to play his instrument. Finally, the diagnosis of an anomaly of the insertion of the palmaris longus tendon was made. After resection of the distal portion of this tendon, the patient's symptoms fully resolved. Anatomic anomalies of the upper limb and particularly of the palmaris longus muscle-tendon unit are frequent and may lead to serious complaints in certain professional groups.
