摘要
[目的]比较导航模板下与传统方法应用动力髋螺钉(DHS)内固定治疗股骨转子下骨折的效果。[方法]选择2009年2月～2010年12月期间接受导航模板与传统方法应用DHS治疗的16例股骨转子下骨折患者资料。随机分成常规手术组及导航模板组,两组均采用动力髋螺钉内固定。导航模板组通过数字化重建技术得到了基于动力髋螺钉个体化导航模板,重建的导航模板有较好的匹配性。采用Harris评分标准对术后随访1年手术效果进行评估。[结果]与传统组比较,导航模板组缩短了手术时间,减少了手术出血量,术后复查X线片见骨折端复位良好,内固定位置良好,应用Harris髋关节评分患者恢复良好,显著提高了手术的有效性,均达到了术前的预期效果。[结论]导航模板下DHS内固定具有缩短手术时间、术中出血量少、安全准确等优点,有其临床应用价值。
[ Objective] To compare the navigation template and traditional method using dynamic hip screw（DHS） fixation in the treatment of subtrochanteric fractures. [ Method ] Sixteen patients with subtrochanteric fracture were treated in our depart- ment from April 2009 to April 2010 and their clinical data were completed. All cases were randomly divided into two groups： the routine Operation and navigation template. In the navigation template group, subtrochanteric fracture mode was constructed by computer-aided design. Operation reposition on femoral subtrochanteric fracture was simulated, the module match with greater trochanter of femur, as well as the screw patch was designed. The post-surgnry effect was evaluated by using Harris scores after 1 year foIlow-up. [ Result] Compared to the routine group, the effect of navigation template group decreased operation duration and bleeding amount with excellent reposition. Harris scores for hip joint showed that the patients recovered well after operation. [ Conclusion] Computer-assisted preoperative design is clinically feasible and useful. The navigation template is a useful method due to its precise localization and direction of screw placement in internal fixation of dynamic hip screw, decreased operation du- ration and less radiation exposure and less blood loss.
