Abstract

BARBATI, A et al. Spontaneous rupture of the digital extensor tendons of the hand in unrecognized carpal lunatefracture. Acta ortop. mex [online]. 2017, vol.31, n.2, pp.91-94. ISSN 2306-4102.

Spontaneous rupture of the digital extensor tendons of the hand has been reported after Kienbock’s disease, rheumatoid arthritis, Vaughan-Jackson’ syndrome, distal radial fracture. Rupture may also occur as a consequence of unrecognized carpal lunate fracture. We present a case report of a man affected with spontaneous rupture of the digital extensor tendons secondary to unrecognized carpal lunate fracture with partial dorsal dislocation. The edges of the tendon were debrided and sutured using a locked modified Kessler suture. A dynamic splinting cast was applied in moderate extension of the wrist. The aim of this case report is to highlight that in absence of a clear etiology for rupture of the extensor tendons of the hand, carpal lunate fracture, though rare, is an important cause of spontaneous extensor tendons rupture.

Keywords : Extensor tendon; carpal lunate fracture; tendon rupture.
