摘要
本实验用犬16条,探索下颌骨火器伤软组织创缘去除的范围;比较骨块移植与带血管复合骨瓣移植Ⅰ期修复的可行性和成骨活动情况。实验表明:弹道软组织切除范围以切除创缘1cm或以出血为清创标准是不准确的;火器伤伤口感染及口腔内伤口未关闭,而引起化脓性骨髓炎及窦道形成是植骨不成功的主要原因;证实了火器伤骨组织缺损早期采用两种骨移植方法均能成活;移植骨为创腔的愈合起到了桥梁和诱导新骨形成的作用。骨缺损区完全以膜内成骨形式愈合。
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.
