Abstract:
The presence of large and massive segmental defects of the diaphyseal bone following tumor resection is a significant problem for orthopedic surgeons. Double or folded free vascularized fibula graft (FVFG) is used in massive femur defects and is considered to be a reliable reconstructive procedure. However, folded or double fibula grafts cannot prevent stress fractures. Here, a novel surgical procedure for bridging of massive femur defects using double FVFG and hydroxyapatite with autogenous bone grafts to prevent stress fractures is reported.
