Clinical Study On Femural Shaft Fracture Treated With Interlocking Intramedullary Nail Through Minimal Invasive Incision

objestive:Through comparing with the closed reduction,a prospective research is given to femural shaft fracture treated with interlocking intramedullary nail through minimal invasive incision.Makes an objective evaluation in term of the feasibility,the clinical curative effect,the security et al,to provide the theory basis for its promotion.Methods:60 patients with femoral shaft fracture who were diagnosed by clinic and X-ray,and were treated in the Mindong hospital of Fujian from March 2006 to April 2007. The youngest is18 year old and the oldest is 60.According to the following up order and the treated method,the patients were divided into two groups:30 patients in the treatment group (inlocking intramedullary nail fixation though minimal invasive incision),and 30 patients in the control group(inlocking intramedullary nail fixation though closed reduction).Different operation method and same treatment after the operation were used,made a follow-up visit for 8-12 months after the patients left the hospital,and reexamine of X-ray were given once two weeks after the operation.We compared each group in term of operate time,blood loss during surgery,the time in hospital,the time for fracture union,the time for bony callus appear,the function of the knees joint of either early time or later period,the rate of occurrence of abnormal union,et al.And made statistics analysis for evaluating the clinical value of this kind of method.Results:Follow-up of 8-12 months for both groups.Clinical bone healing was achieved,no fat embolism syndrome,infection or break of nail occurred in both groups. The average time of operation was(84.17±16.67) min in the treatment group and (124.26±29.91)min in the control group,and the average blood loss during surgery was (128.33±33.41)mi and(155.00±52.95) ml,respeatively.Via T-test,we could see that there is significant difference between the two groups in them(P＜0.05),According to the Liu Xing yan's score standard,the two groups are equal in the comprehensive curative effect,there is no significant difference between the two groups in it(P＞0.05).and there is no significant difference between the two groups in the time in hospital,the time for fracture union,the time of callus appearing,the function of the knees joint either early time or later period,the number of abnormal bone union(P＞0.05).Conclusion: 1.The minimal invasive incision reduction keep the closed reduction's advantages of fewer invasions,steady fixation,short healing time,well function recovery,et al.2.Compares with the closed reduction,the treatment therapy that inlocking intramedullary nail fixation through minimal invasive incision for treating femoral shaft fracture has a better feasibility and the usability,the surgery time is shorter,the blood loss is less during surgery,X-rad harm is avoided.So,Its application prospect is magnificent.
