A comparative study of dynamic hip screw and locking comprass plate in treatment of femoral intertrochanteric fractures

[Objective]To compare the therapeutic effect on femoral intertrochanteric fractures with dynamic hip screw(DHS) and locking comprass plate(LCP).[Method]A retrospective study of 90 patients with femoral intertrochanteric fractures treated in of 458 hospital from March 2005 to December 2008 was carried out.46 patients were treated with DHS,and 44 with LCP.The operative time,blood loss,walking time,union time and hip function scores were recorded and statistically analyzed.[Result]All the patients were followed up for 6-18 months(mean,12.8 months in average).Operative time in the LCP group was shorter than that of DHS group(P≈0.0002).Blood loss in the LCP group was less than that of DHS group(P≈0.0006).Walking time in the LCP group was shorter than that of DHS group(P≈0.001).There was no significant difference in union time(P≈0.082)between the two groups.There was no significant difference in the excellent and good results between the two groups in stable femoral intertrochanteric fractures(P≈0.064)either.The excellent and good results of LCP group was significantly higher than DHS group in unstable femoral intertrochanteric fractures(P≈0.0001).[Conclusion]Both technigues have their own advantages and indications.They are both effective for stable femoral intertrochanteric fractures.LCP has more advantages and indications for unstable femoral intertrochanteric fractures.
