    Abstract:
    PURPOSE: We report the oncological and functional results of limb salvage for bone sarcomas involving the distal tibia using hybrid surgical technique of resection arthrodesis by bone transport then plating. METHODS: Five patients (mean age 18.6 years) with primary distal tibial sarcomas (two Ewing's sarcomas and three osteosarcomas) were treated by this method. The average duration of follow-up is 53 months. All patients accepted distraction osteogenesis with a standard technique using external fixator after wide (four cases) or marginal (one case) resection in the first operation. They were re-admitted for the second surgical treatment (plate insertion and removal of the external fixator) one to two months after they achieved the necessary limb length and desired alignment. RESULTS: Solid union of the lengthening site and sound fusion of the ankle were achieved in all five patients with full and unassisted weight bearing. The mean lengthening was 11.8 cm (range 8-14 cm) and the external fixation index (EFI) was 29.3 days/cm (range 22.8-36.3 days/cm). The mean functional score according to the rating system of the Musculoskeletal Tumour Society was 88% (83-90%). One patient showed poor response to chemotherapy, had local recurrence of sarcoma one year after plating, and was treated with above-knee amputation. CONCLUSIONS: In carefully selected patients with primary distal tibial sarcomas, this hybrid method can effectively eliminate tumor lesion, reconstruct function, and shorten the length of wearing an external fixator by a meticulous conversion to internal fixator.
