Bone resorption of the proximal phalanx secondary to pulley reconstruction

摘要

We report a case of bone resorption of the proximal phalanx secondary to A2 pulley reconstruction without any prior history of bony or vascular injury. A 27-year old female sustained lacerations to her dominant ring and little fingers, with complete division of both flexor digitorum superficialis (FD5) and flexor digitorum profundus (FDP) tendons. There was no history of prior injury. There were no bone or neu-rovascular injuries (Figure 1 (a)). She underwent acute repair of her FDP tendons. This was complicated by a superficial wound infection and subsequent stiffness of the proximal interphalangeal (PIP) joints. Tenolysis was performed in both fingers in order to improve range of motion (ROM). There was an improved ROM, but she developed bowstringing in both fingers.
