The Clinical Research Of Contrast For Internal Fixation Of Dynamic Hip Screw (DHS )and Gamma Nail In Treatment Of Intertrochanteric Fracture

Objective:to study the clinical curative effect of contrast of the dynamic hip screw application (DHS )internal fixation and Gamma nail internal fixation for intertrochanteric fractures (EvansⅢ).Methods: All patients were from Orthopedics of Affiliated Hospital of Changchun University of Chinese Medicine and Suzhou Hospital of Traditional Chinese Medicine since 2010.2-2011.4 , according to case the inclusion criteria and exclusion standard, the choice of intertrochanteric fractures within 60 cases, including DHS 30 cases and Gamma nail fixed within 30 cases of fixed. We had comparative analysis by SPSS by the gender,age,the original incidence,postoperative complications and recovery and the mean operative time,incision on average,the amount of bleeding during surgery,and the lost degree of postoperative neck-shaft angle . the data was analysed by statistical software package of SPSS for windows13.0 .Results:The effective rates and the incidence rates of hip joint valgus of dynamic hip screw(DHS)group and Gamma nail group had no distinct difference by treating statistically (P>0.05), Excellent rate of Gamma nail group and DHS group were similar ,Gamma nail group was less than DHS group in the timing of the operation and the amount of bleeding during surgery.Conclusion : DHS and Gamma nails are the ideal materials to fixation of intertrochanteric fractures .Gamma nail is superior to DHS in terms of controlling operative trauma.
