BackgroundLarge bone defect in infant or small patients has been little reported and the management of such a patient is difficult. Considering the little knowledge of this area, we present this special case of a successful single-cortex fibula graft for the treatment of a large tibia bone defect in a 2-year-old patient to share our experience.Case SummaryA 2-year-old male patient presented to our hospital with history of leg pain for 4 months. According to his medical records, he was involved in a traffic accident and diagnosed with open tibia fracture. A previous surgery of emergent debridement and external fixation was performed in our institution, leaving a 6-cm tibia bone defect. After that this patient received several times of vacuum sealing drainage (VSD), skin grafting, and changed external fixation to cast because of pin tract infection.The physical examination of the patient showed a healed skin wound and a good dorsal arterial pulse. X-ray indicated a large bone defect at the tibia fracture site with osteosclerosis at the fracture sections. This patient received ipsilateral single-cortex vascularized single-cortex fibula graft, other than double-cortex fibula graft. X-ray and CT scan 4 months after the operation confined bone healing. The patient returned to normal activities with an inconspicuous limb.ConclusionIpsilateral single-cortex fibula graft is effective for the treatment of large tibia bone defect in infant or small aged patients. It exhibited better potential benefits than double-cortex graft in such cases.
