title: Cylindrically modeled bone grafts.
abstract: A technique of autogenous grafting for repair of large defects in long bones is presented. Quadrangular grafts, taken from the external table of the posterior ilium, are modeled by bending them into cylindrical form, which has higher mechanical resistance as compared to flat struts. Cancellous chips are added. The original shape of the bone is immediately restored, and heavy internal fixation is avoided. combination of cortical and cancellous bone grafts provides both strength and rapid bone healing. There is no risk of fracture at the donor site. Of eight consecutive cases operated on, seven were successful. One failed because of relapsing infection. The procedure is suitable in children, adolescents, and young adults, for difficult cases of large defects in long bones left after resection of tumors and tumor-like conditions, as well as after diaphyseal distraction for leg lengthening.
