Abstract

Some of the techniques for bone grafting for delayed union or nonunion of the long bone are used currently. In 1991, at arthroscopy workshop in Phoenix, Arizona, Lanny L. Johnson, M.D. reported a case of endoscopic bone grafting for the delayed union on the humerus. He suggested the possibilities of endoscopic bone grafting such as minimal incision, magnified visualization, accurate debridement, accurate graft placement, vascular preservation, outpatient surgery and reduced cost. The author performed endoscopic bone grafting and extra-articular adhesionlysis on the delayed union of femur with extra-articular ankylosis. The patient was a 28 year old housewife with blood type Rh(-). The duration after initial operation was more than 9 months. The result of the graft was satisfactory. In the future endoscopic bone grafting could be performed for nonunion, delayed union and congenital bone defect.
