Abstract

Carpal tunnel syndrome (CTS) represents the most common entrapment neuropathy of the upper extremity. Intermittent CTS has been reported in the surgical literature and usually, related to masses associated to flexor tendons. We describe a patient with an intrasynovial lipoma involving the deep flexor of the middle finger causing intermittent CTS and snapping on flexion–extension.

Sommario

La sindrome del tunnel carpale (CTS) rappresenta la neuropatia da intrappolamento più comune dell’arto superiore. La CTS intermittente è stata riportata nella letteratura chirurgica e, di solito, in relazione alle masse associate ai tendini flessori. Descriviamo un paziente con un lipoma intrasinoviale che coinvolge il flessore profondo del dito medio che causa CTS intermittente e che si spezza sull’estensione della flessione.
