Comparison on blood indices after treatment of intertrochanteric fractures with conventional and minimally invasive DHS internal fixation in the elderly / 中华创伤杂志

ABSTRACT

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.
