Outcome of treatment of complex, perilunate fracture-dislocation of the wrist: a case report.

Complex, perilunate fracture-dislocations of the wrist comprise severe and challenging injuries, characterised by a total loss of contact between the lunate bone and the head of the capitate as well as fracture of one, or more bones surrounding lunate bone. The principle of treatment of such injuries involves stable fixation of fractures, anatomical reduction of the displaced carpal bones with temporary arthrodesis wit K-wires to maintain their position. We present a patient who sustained a complex, perilunate fracture-dislocation of the wrist with fractures of the scaphoid, hamate and base of the IV metacarpal bone, as a result of a blast. Assessment at one year after the surgery showed satisfactory result: mean range of motion in the wrist was 50-60% of the healthy side, grip strength was 55%, DASH score of 36 and Mayo score of 65.
