Abstract：Objective To investigate the efficacy of proximal femoral nail anti-rotation Ⅱ( PFNA-Ⅱ) and the third-generation Gamma nail ( TGN) in the treatment of femoral intertrochanteric fractures .Methods Totally 172 cases of fracture in our hospital from Jan .2009 to Dec.2012 were selected and randomly divided into 2 groups, 86 cases in each group .Among these patients 75 were male and 97 were female ,ranged from 35 to 82 years with an average age of (63.4+14.8) years.Patients in the control group were treated with TGN and those in the observa-tion group were treated with PFNA-Ⅱ.Surgical incisions , postoperative functional scores and complications were compared.Results The operation time,fluoroscopy times and blood loss were (59.4 ±19.7)min,(18.6 ±2.4) times and (152.3 ±109.4)ml,respectively,which were significantly lower than those of the control group [(76.8 ± 23.8) min,(22.4 ±2.7) times,(188.4 ±128.5) ml,P<0.05];the incision length of PFNA-Ⅱ and TGN group was (7.4 ±2.2) cm and (6.7 ±2.4)cm,respectively,indicating no significant statistical difference (P>0.05);the fracture healing time and hip score of the PFNA-Ⅱgroup were (11.8 ±2.6) weeks and (85.3 ±13.9),respective-ly,while those of the TGN group were(12.6 ±2.5) weeks and (83.7 ±15.4),respectively, the difference was not statistically significant(P>0.05).Neither group developed surgical cutting of the femoral head ,fixation breakage, nonunion or other complications .Conclusion Compared to TGN ,the operation time , fluoroscopy times and blood loss of PFNA-Ⅱare significantly lower ,while there is no significant difference on intraoperative complications and postoperative functional scores .
