Background: Perilunate fracture dislocation and perilunate dislocation are rare injuries which their treatment can be challenging especially in chronic cases. In this study we report the result of two stage treatment of these injuries by using a distracting external fixator. The external fixator has been mounted in the first stage and after distraction; the second stage or open reduction was performed after 3-4 weeks.
Methods: In this retrospective study, seven patients underwent 2 stage treatment. Final assessments were include: Pain assessment using Visual Analogue Scale (VAS),functional evaluation of the wrist by  Disabilities of the Arm, Shoulder, and Hand (DASH), power and pinch grip assessment, radiocarpal range of motion and arthrosis in the radiocarpal and mid carpal joints.
Results: Mean duration between injury and surgery was 7±4.9 months. Mean follow up period was 16.8±10.7 months. Power grip of the injured hand was 82.1% of the normal one. Pinch grip of the involved hand was 82.5% of the counterpart hand. Range of motion in the radiocarpal joint of the injured hand was 49.6% in flexion / extension and 64.6% in ulnar/radial deviation of the uninjured hand, respectively. Mean VAS and DASH score were 4.1 and 28.5 respectively. Scaphoid non::::union:::: was seen in one patient and radiocarpal joint arthrosis occurred in another one. 
Conclusion: According to the acceptable result of this study, we recommend two stage treatment of old perilunate injuries.
Type of Study: Research | Subject: Orthopedic
