Physeal-sparing unreamed locked intramedullary nailing for adolescent tibial fractures.

INTRODUCTION

The first-line treatment of paediatric tibial fractures is non-operative but the number of operatively treated patients is rising. Elastic intramedullary nailing and external fixation are widely used in children while solid intramedullary nailing, the standard procedure in adults, is usually not recommended due to the open physes.

MATERIALS AND

METHODS

Between January 2007 and October 2017, unreamed locked solid intramedullary nailing was used in 16 cases of adolescent (mean age 13.7 ± 1.25 years) tibial diaphyseal fractures with open physes. An atypical, physeal-sparing method was used in all cases. Fourteen patients were managed by the standard implant used routinely in adult trauma care. Two patients were treated by a special nail, modified specifically for paediatric care.

RESULTS

Good functional healing was found in all cases treated by the atypical method. Partial weight bearing began immediately after surgery in 38% of the cases. Full weight bearing was allowed 7.3 ± 2.4 weeks postoperatively. The average time to fracture union was 11.5 ± 2.9 weeks. Superficial infection and wound healing complication occurred in 3 cases. Deep infection, compartment syndrome or other bone related complications did not arise.

DISCUSSION: The treatment of tibial fractures in adolescents is challenging due to larger body size and significant growth potential. The atypical intramedullary nailing method presented in this study can provide optimal functional healing, early mobilization and weight bearing while completely sparing the physis. This method can serve as an alternative in the operative treatment of adolescent tibial diaphyseal fractures.
