Abstract:
[Objective]To evaluate the reliability of proximal femoral nail anti-rotation(PFNA) in treatment of intertrochanteric fracture using K-wire apex distance(KAD) intraoperatively to control tip apex distance(TAD).[Method]From January 2007 to January 2009,44 cases of intertrochanteric fractures were treated by closed reduction internal fixation with PFNA.Intra-operative KAD and post-operative TAD were measured and analyzed for their correlation.[Result]Follow-up was given to 42 patients for 6-18 months(averaged,10 months).Bone union was achieved after 11-23 weeks(averaged,13 weeks).Intra-operative KAD were 13-31 mm,with an average of 21.75 mm.Post-operative TAD were 18-35 mm,with an average of 24.61 mm.Recurrence of cerebral infarction was found in 1 case.No infection,deep vein thrombosis,intramedullary nailing rupture,screw broken or femoral fracture was found.[Conclusion]With the help of intra-operative fluoroscopy,the distance from the end of Kirschner's wire to joint surface(KAD) plays an important role in controlling TAD,and it could prevent relative complications such as helical blade cutting-out of femoral head.
