ABSTRACT
BACKGROUND:
With the advent of modern limb salvage techniques, segmental bone loss in the lower extremity has become more common.METHODS:
To aid preoperative planning when dealing with segmental bone loss in the femur and tibia, we performed a cadaveric study to estimate the volume of autogenous or allograft material required to fill defects located in various areas of the bones.RESULTS:
The greatest volume was generally required in metaphyseal defects, with an average of 12 cc/cm in the distal femur and proximal tibia, 11 cc/cm in the proximal femur, and 6 cc/cm in the distal tibia. Diaphyseal defects were found to have the least variability with regard to the volume of graft material required for different specimens. Femoral diaphyseal defects required 7 cc/cm and tibial diaphyseal defects required 5 cc/cm. A slightly larger volume of allograft material was needed to fill all defects compared with autograft.CONCLUSION:
This method allows one to estimate the amount of graft required for a defect of the femur and the tibia.
