Callus Distraction Lengthening of the Tibia with the Intramedullary Kinetic Nail (Case Report)

Abstract

In this report the first experience with callus distraction lengthening using the intramedullary kinetic nail is described. This was performed on a left tibia with a total shortening of 34 mm. The distraction phase lasted 36 days and the rate of distraction was 0.95 mm per day. The full weight-bearing of the treated lower extremity was allowed at 12 weeks after surgery. Complete consolidation of the callus was achieved at 112 days and the consolidation index was 3.21 days/mm. No serious complications were recorded during the post-operative period. At 12 months after surgery, the patient showed a full range of motion in the knee, his ankle range of motion was S 15-0-35, and he achieved an excellent functional outcome on evaluation by Paley's classification.
