A comparative study of dynamic hip screw and proximal femoral nail antirotation in treatment of femoral intertrochanteric fractures / 中国矫形外科杂志

ABSTRACT

[Objective]To compare the therapeutic effect on femoral intertrochanteric fractures with dynamic hip screw(DHS) and proximal femoral nail antirotation(PFNA).[Method]A retrospective study of 483 patients with femoral intertrochanteric fractures in Changhai Hospital from December 2001 to January 2008 were carried out.Totally 109 patients were treated with PFNA,while 374 patients were treated with DHS.The data of operative time,blood loss,walking time,union time and hip function scores were recorded.[Result]All the patients were followed up for 6～38 months(15.3 months in average).There were significant differences in operative time,blood loss and walking time between two groups.There were no significant difference in union time.There were no significant difference in the excellent rate between the two groups in stable femoral intertrochanteric fractures.The excellent rate of PFNA group was significantly higher than DHS group in unstable femoral intertrochanteric fractures.[Conclusion]Each of them have its own advantages and indications.Both are effective ways to treat stable femoral intertrochanteric fractures.PFNA has more advantages to treat unstable femoral intertrochanteric fractures.
