Abstract:
Objective To discuss the clinical effect of dynamic hip screw(DHS)and microtrauma dynamic hip screw(MTDHS)in treatment of comminuted intertrochanteric femur fractures in the elderly patients.Methods From September 2006 to July 2009,42 patients with comminuted intertrochanteric femur fractures were treated by DHS and MTDHS.According to Evans classification,there were 16 patients with type Ⅲ fractures and six with type Ⅳ fractures in MTDHS group and 15 patients with type Ⅲ fractures and five with type Ⅳ fractures in DHS group.The operation time,amount of bleeding,hospital stay and postoperative hip function were evaluated.Results All patients were followed up for 9-17 months(average 13 months).Harris score was 76.4 points in 20 patients treated by DHS and 89.8 points in 22 patients treated by MTDHS,with better functional restoration,shorter operation time and less amount of bleeding in MTDHS group than DHS group.Conclusions Compared with DHS,MTDHS has advantages of minimal invasion,minor trauma,sound recovery of hip joint function and low incidence of complications and hence is a good choice for treating intertrochanteric femur fractures.
