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.
ABSTRACT
[Objective]To investigate the effect of using Minimully invasive percutuneous plate osteosunthosis to insert DHS for fixation of intertrochanteric hip fractures in elderly patients,in order to reduce operative trauma.[Method]To study retrospectivly 75 cases of the intertrochanteric fracture of elderly patients treated with DHS,these patients were treated from july 2004.7 to october 2005.10.MIPPO was used in 29 out of 75 cases,classic technique for fixation was used in other ones.[Result]All patients successfully discharged except two died because of fungal septicemia and lung embolism.Totally 73 cases were followed up from 7 to 21 months(averagd 12.3 months),one died of morbus internus in follow-up period.All the fractures had successful union,union time in average was 3.5 months,the diference between MIPPO group and classic incision group was not distinguished.Blood loss and transfusion in MIPPO group was less than classic incision group.Recovery of ESR and detumescence of the femoral was quickly in minimal incision group,time in bed was short.[Conclusion]Technique of minimal invasive fixation using DHS has little trauma and quick functional recovery for patients,therefore,this technique should be better for treatment of intertrochanteric fracture in elderly patients.
