Therapeutic effect analysis of three internal fixation methods in the treatment of intertrochanteric femur fracture / 中国矫形外科杂志

ABSTRACT

[Objective] To discuss the therapeutic effect of different methods in the treatment of intertrochanteric femur fracture. [Methods]Totally 118 middle aged or old patients with intertrochanteric femur fracture were fixed with dynamic hip screw (DHS), Gamma nail or PFNA.[Results]Totally 112 cases were followed up, and the average time was 16 months, in those 45 patients were fixed with DHS 29 were excellent, 11 cases were good, and 5 were poor, and the excellent to good rate was 88.9%; 36 patients were treated with Gamma nail, and the excellent, good, poor results were 28, 2, 1, respectively, and the excellent to good rate was 96.8%; 36 patients were fixed with PFNA, and the excellent, good, poor results were 29, 6, 1, respectively. The differences were significant (P=0.02, analyzed by Logistic regression with SPSS software). The excellent and good superiority of Gamma nail and PFNA were 5.1552 and 2.3726 times compared to DHS, and there was significant differences between the groups.[Conclusion]Surgical treatment of intertrochanteric femur fracture can improve the functional recovery and reduce the complication incidence, and PFNA fixing method can shorten the operative time, reduce the bleeding and the therapeutic effect is reliable, and suitable for old patients combined with osteoporosis.
