股骨转子间骨折动力髋螺钉内固定微创法与常规法术后部分血液指标的比较

目的 比较微创动力髋螺钉(DHS)内固定与常规方法内固定治疗老年股骨转子间骨折时部分血液检测指标的变化,揭示微创手术对机体生理干扰程度. 方法 将2004年7月-2006年5月我科收治的老年股骨转子间骨折患者随机分为两组:一组采用常规DHS内固定治疗(52例),另一组采用微创DHS内固定治疗(54例).对手术前后白细胞(WBC)、血红蛋白(Hb)、红细胞沉降率(ESR)、C反应蛋白(CRP)、肌酸激酶(CK)等血液检测指标及隐性失血量进行比较分析. 结果 微创组输血量、出血量、隐性失血量、ESR、CK变化明显少于传统组,差异有统计学意义,而两组间WBC和CRP变化差异无统计学意义. 结论 微创DHS内固定术治疗老年股骨转子间骨折能够减少手术创伤.

Comparison on blood indices after treatment of intertrochanteric fractures with conventional and minimally invasive DHS internal fixation in the elderly

Objective To compare the changes of some blood indices after treatment of intertro-chanteric fractures with conventional and minimally invasive dynamic hip scres (DHS) internal fixation so as to understand the influence of minimally invasive technique on physiology of the organism. Meth-ods The elderly patients with intertrochanteric fractures in our department from July 2004 to May 2006 were divided randomly into two groups, ie, conventional DHS internal fixation group(Conventional group, 52 patients)and the minimally invasive DHS internal fixation group(Minimal invasion group, 54 patients). A comparison was done on data including white blood cells (WBC), hemoglobin (Hb), e-rythrocyte sedimentation rate (ESR). C reactive protein (CRP) and creatine kinase (CK) as well as re-cessive blood loss. Results The indices including transfusion, blood loss, recessive blood loss, ESR and CK in minimal invasion group showed less changes compared with conventional group. With statistical difference. But WBC and CRP showed no statisfical difference between both groups. Conclusion Minimally invasive DHS internal fvtation carl reduce operative trauma during treatment of intertrochanterie fractures in the elderly.
