    Journal: Zhonghua Wai Ke Za Zhi; 1999 Aug; 37(8):503-6, 36. PubMed ID: 11829902.
    Abstract:
    OBJECTIVE: To study the treatment of gunshot bone defect and the biological basis of primary shortening followed by callus distraction in situ. METHODS: The canine with gunshot bone defect were treated by two methods, primary shortening followed by callus distraction or delayed bone graft. The local blood flow and pathomorphological change were observed and compared with each other. RESULTS: In the experiment, the bone lengthening was stopped at the 56th day with (2.82 +/-e 0.94) cm (19.3%) gain in the group of bone lengthening, and the time of bone healing was much shorter in the group of bone lengthening than in the group of delayed graft. There was no significant difference between the groups in the time of soft tissue healing and local blood flow. CONCLUSIONS: The technique of primary bone lengthening is simple and has no side effect on tissue healing and local blood flow.
