ABSTRACT
Objective To compare proximal femoral nail(PFN)introduction by percutaneous K-wire through a small incision with conventional PFN introduction protocol in the treatment of intertrochanteric fractures. Methods From January 2004 to March 2005,51 patients with intertrochanteric fractures were randomly dis- tributed into a minimally invasive treatment group(group MI)and a conventional treatment group(group C).All the fractures were closely reduced.In group MI a K-wire was percutaneously inserted through the tip of the greater troehanter into the center of medullary canal of the pruximal femur before the PFN was inserted under the guidance of K-wire through a small incision made along the K-wire while in group C the PFN was introduced according to the conventional procedure.The operation time,intra-operative blood loss,length of incision,X-ray exposure,duration of in-patient stay and time of bone union in both groups were recorded and compared.Results The mean oper- ation time,mean intraoperative blood loss and mean length of incisions in group MI were 77.20 min,104.20 mL and 5.12 cm respectively and significantly lower than those in group C(P<0.01).The X-ray exposure and the reduction time in group MI lasted longer than in group C(P<0.01).The mean time of bone union and in-patient stay in both groups were nearly equal(P>0.05).At the latest tollow-up,all the fractures united in both groups without nonuuion or delayed union.Conclusion Compared with the conventional protocol,introduction of PFN by a pereutaneuus K-wire inserted into the central medullary canal of the proximal femur is much more minimally in- vasive and effective.
