Treatment of trans-scaphoid perilunate dislocations using a volar approach with scaphoid osteosynthesis and temporary Kirschner wire fixation.

Trans-scaphoid perilunate fracture dislocations (TSPLD) are uncommon injuries and constitute about 3% of all carpal injuries. Up to 25% of these high energy trauma cases go undiagnosed. Presented are 43 (3 female, 40 male) consecutive patients treated for dorsal TSPLD, all were closed fractures. Patients were between 17 and 66 years old. Twenty male patients were injured in active duty military service. Surgical treatment was made with a volar approach using titanium cannulated headless compression screws (3.2 mm) placed via a guide wire. Repositioning the dislocated carpus is then conducted using 3 temporary fixation Kirschner wires (1.6 mm). The patient had a volar short arm splint for 4 weeks, then given an orthosis. Triple fixation Kirschner wires were removed 6-8 weeks postoperatively. Mean followup period was 29 months (range 20-38). The average Mayo wrist score for all 43 patients is 87 (good) (range 65-99). All patients returned to their previous employment.
