(b) A window in the cortical bone was made. (c) To remove mass using a series of curettes of various sizes. (d) To polish the residual tumor cavity with a high-speed burring until reaching the normal cortical bone. (e) To fill the residual tumor cavity with allogenic particle bone graft and covered the windowed cortical bone.
