Abstract:
The purpose of this study was to determine the debriding scope of soft tissues in gunshot wound, and to compare the feasibility of one-stage bone graft transfer between nonvascularized and vascularized bone grafts in 16 dogs.The results demonstrated that it was not accurate to excise the soft tissue till bleeding or to excise only 1cm around the trajectory.The major reasons for the failure of bone transplantation were wound infection, oral open wound, and subsequent infectious myelitis and formation of fistula.Both the nonvascularized and vascularized bone grafts survived at the early stage.The transplanted bone served as bone bridge, and induced the formation of new bone.The bone defect was repaired by membranous bone formation.
