A) Resected specimen after enbloc excision of GCT of proximal tibia. B) The tumour resection leaving a gap of around 14 cm. C) The gap being partially bridged by intercalary dual fi bular graft with intramedullary K-wire. D) The fi bular graft being augmented by copious cortico-cancellous graft. The extremity is stabilized by ring fixator for simultaneous limb lengthening. E) Postoperative radiograph of the patient showing dual intercalary fi bular graft with intramedullary K-wire. A distal tibial corticotomy has been performed for limb lengthening. F) Followup of the patient showing crossunion between the dual fi bular graft. The regenerate for limb lengthening is beginning to consolidate.
