Preliminary report on treatment of perilunar fracture dislocation

ABSTRACT

Perilunate dislocation and fracture dislocations are uncommon injuries of the wrist. The aim of the present study was to present an experience in treating such rare injuries. Nine patients were treated within three years [two patients were lost in follow up and the remaining seven patients had an average follow up of 25.8 months]. There were two perilunate dislocations and five fracture dislocations. The fracture dislocation group was treated within hours of injury. The two perilunate dislocations were delayed for 7 and 17 days post injury; these two cases had open reduction and percutaneous fixation. The fracture dislocation group had an immediate closed reduction and percutaneous fixation of the fracture and intercarpal joints. One case had open reduction and Herbert screw fixation of the scaphoid fracture with percutaneous fixation of the intercarpal joints. A functional scoring system and X-ray findings were used for the follow up evaluation. Three patients had excellent results, three patients had good results and one had fair result:
