[Free fibular flaps in children: morbidity of the donor site and pitfalls to avoid].

INTRODUCTION

We report a case of donor site morbidity late after harvesting a free fibular flap for reconstruction of the mandibular symphsis.

CASE REPORT: An 8-year-old boy presented a valgus deformity of the ankle 4 years harvesting of a vascularized fibular graft for mandibular reconstruction. The deformation was repaired with a tibial bone slit and pin fixation. The biomechanical result was very satisfactory, allowing normal gait.

DISCUSSION: We recall the rules for fibular flap harvesting needed to prevent deformation of the donor site in children aged less than 9 years.
