Abstract
Objective To observe the clinical effect of extended proximal femoral intramedullary nail(extended PFNA) for the treatment of middle and proximal femoral fractures.Methods 25 cases of patients with middle and proximal femoral fractures that were treated and followed up in our hospital from January 2012 to July 2015 were retrospectively analyzed,17 cases of male,8 cases of female;age ranged from 36 to 85 years old,average 56.3 years old;all patients were unilateral closed femoral fracture,time interval from injury to surgery is 1 d ～ 9d,average 4.7d.The patients were followed up regularly at 1,2,3,6,9 and 12 months after surgery at outpatient department.Harris hip function score was used to evaluate the clinical efficacy.Results The intraoperative bleeding volume was 55 ～ 430 ml,average 108.3 ml,operation time was 52 ～ 117 min,average 63 min;all patients could walk with stick 5 ～ 21d after the operation.25 patients were followed up completely,the fracture healing time was 2.5 ～6.5 months,average 3.8 months.At the last follow-up,according to the Harris hip function scoring criteria,19 cases were excellent,5 cases were good,1 case was middle,the excellent and good rate was 96％ (24,25).No infection or nonunion occurred in all the patients,2 cases of mild coxa vara shortened deformity,3 cases with lower extremity intermuscular vein thrombosis and the thrombosis was not aggravated by medication.Conclusion Extended PFNA can fix the peritrochanteric fracture and Femoral shaft fracture at the same time,it has advantages such as less bleeding,reliable fixation,good biomechanical properties,fast function recovery and less complications,and it is the treatment of middle and proximal femoral fractures with minimally invasive and effective.关键词
