Triggering Secondary to an Untreated Partially-Cut Flexor Tendon

Abstract

A case is reported where a flap cut of the radial slip of the flexor digitorum superficialis triggered on the proximal border of the A2 pulley within a healed intact tendon sheath. Shaving the flap resolved the problem. This illustrates another post-traumatic mechanical cause of triggering after partial division of flexor tendons.
