Abstract：Objective To explore the curative effects of dynamic hip screw guide system ( DHSA) and dy-namic hip screw ( DHS) in the treatment of femoral intertrochanteric fracture in elderly patients .Methods Totally 68 patients over the age of 65 who suffered from femoral intertrochanteric fractures from Jan .2011 to Jan.2013 were retrospectively studied .Among them ,37 cases were in DHS group and 31 cases in DHSA group .Preoperative basic information(gender,age,side of injured limb,fracture type,preoperative complications),intraoperative average oper-ation time,average blood loss,cut-out of femoral head,time of union and Harris score of the two groups were com-pared.Results The mean period of follow-up was(21.5 ±8.5)months (range,9 to 32 months).Preoperative basic situation of the two groups had no statistically significant difference (P>0.05).No infection and cut -out of femoral head occurred in DHSA group .Shorter operation time , less intraoperative bleeding and faster average heal-ing time were found in patients in DHSA group .Harris score in DHSA group was significantly higher than in DHS group and the difference was statistically significant ( P<0.05).Conclusion DHSA and DHS can achieve good fixation for elderly femoral intertrochanteric fractures .DHSA technology has advantages such as reliable fixation ,an-ti-rotation,reduced cut-out,cancellous bone filling,less surgical trauma.It is more suitable for osteoporotic intertro-chanteric fracture patients and worth of clinical promotion and further in-depth study .
