We have treated 50 patients with bony malignancy by en bloc resection, extracorporeal irradiation (ECI) with 50Gy and re-implantation of the bone segment as a method of limb salvage. Mean survivor follow-up is 38 months (12–92). 42 patients remain alive without disease. 4 recurrences occurred. Functional results were generally good: Mankin grades 17 excellent, 13 good, 9 fair, 3 failures; MSTS mean 77 (20–100); TESS mean 81 (40–100). Solid bony union was the norm, however bone resorption was seen in some cases. The dose of radiation is theoretically lethal to all cells and produces a dead autogenous bone graft of perfect fit. ECI is a useful technique of limb salvage where there is a reasonable residual bone stock. It allows effective re-attachment of muscle tendons, and produces a lasting biological reconstruction. The risk from the re-implanted bone of both local recurrence and of late radiotherapy induced malignancy should be nil.
