Abstract：Objective To investigate the effects of different kinds of internal fixation schemes including dynamic hip screw ( DHS) ,intramedullary nail and PFNA-Ⅱon the blood coagulation function and DVT incidence in patients with femoral intertrochanteric fracture. Methods One hundred and fifty patients with femoral intertrochanteric fracture who were treated in our hospital from July 2011 to July 2016 were randomly divided into group A ( n =50),group B ( n =50) and group C (n=50) , and the patients in group A, B, C were treated by DHS, intramedullary nail, PFNA-Ⅱ, respectively. The surgical duration,incision length,intraoperative blood loss volume,the levels of Hb, Hct, PLT, TT, APTT, PT, FIB and D-dimer and the incidence rate of DVT were observed and compared between the three groups. Results The operation incision length in group B and group C were significantly shorter than that in group A ( P <0. 05). The surgical duration and intraoperative blood loss volume in group C were significantly less than those in group A and B group ( P <0. 05). The levels of Hb and Hct on 7d after operation in group C were significantly higher than those in group A and group B ( P <0. 05). Moreover the levels of PLT,APTT,PT,FIB and D-dimer on 7d after operation in group C were superior to those in group A and group B (P<0. 05). The levels of TT on 7d after operation in group B and group C were suprior to those in group A ( P <0. 05). Moreover the incidence rates of DVT in group B and group C were significantly lower than those in group A ( P <0. 05). Conclusion The PFNA-Ⅱ scheme in treatment of femoral intertrochanteric fracture can effectively reduce postoperative recessive blood loss volume, improve blood coagulation function,moreover,which can prevent occurrence of DVT,thus,which is superior to DHS and intramedullary nail.
