A Case of Bilateral Carpal Tunnel Syndrome with Palmaris Longus and FDS Anomalies

Zusammenfassung

Wir präsentieren einen Patienten mit bilateralem „Karpaltunnelsyndrom“ verursacht durch zwei verschiedene Muskelanomalien. Es wurden bisher mehrere Muskelanomalien im Zusammenhang mit dem Karpaltunnelsyndrom definiert. Aber ein Patient mit Flexor digitorum superficialis-Anomalie einerseits und Palmaris longus-Anomalie andererseits war bis jetzt unbekannt. Muskelanomalien sollen in der Ätiologie des Karpaltunnelsyndroms in Betracht gezogen werden, obwohl sie sehr selten vorkommen.

Abstract

We report a case of bilateral carpal tunnel syndrome due to two distinct muscular anomalies coexisting with trigger finger deformity. Many muscular anomalies in association with carpal tunnel syndrome have been described so far. But such a unique case of bilateral carpal tunnel syndrome with two different muscular anomalies, flexor digitorum superficialis anomaly on one side and palmaris longus anomaly on the other side has not been described. Even rare, muscular anomalies should be considered in the aetiology of carpal tunnel syndrome.
