Analysis Of The Impact On The Efficacy PFNA Treatment Of Elderly Intertrochanteric Fracture Of The Imagingposition

ObjectiveAway by the Proximal femoral nailanti-rotation (PFNA) treatment in elderly intertrochanteric fracture imaging in the steeple that is, TAD (after the spiral blade instantly lateral radiographs vertex to the femoral head-the neck axis and shares bones, joints personal point distance),data and postoperative function scoreanalysis, the PFNA treatment of elderly intertrochanteric fractures of the best imagingposition to guide clinical elderly femoral intertrochanteric fractrue surgery in the spiralblade away from the posintion of the femoral head vertex placed to achieve optimm recovery of hip function effect.MethodsAnti-rotation of the proximal femur locking intramedullary nail (PFNA)118cases of elderly patients with intertrochanteric fractures treated from March2010to October2011and TAD (postoperative lateral radiographs of the instantly on the spiral bladevertex to the femoral head-the neck axis of the femoral head articular personally point distance) calculation, based on the measured value of TAD is divided into three groups:group A:TAD<20mm total of48cases; group B:20mm≤TAD<30mm,49cases; group C:TAD≥30mm of21cases, and the application the Senders hip score of their efficacy analysis.47cases were male and71cases, female, male to female ratio1:1.5. Age of55-103years, mean age of82.5years. According to intertrochanteric fracture modified Evens sub-type, of which31cases of type Ⅰ, Ⅱ,41cases,28cases,13cases of type Ⅳ, Ⅴ five cases of type III. SPSS17.0statistical package, will be the score as the dependent variable, the TAD value, age, fracture type, the quality of reduction as the independent variable, respectively, using the χ2test, χ2test, Wilcoxon rank sum test of the correction, P<0.05significant difference, kicking in addition to the non-statistically significant variables.Result1.A follow-up time of6-24months, with an average of15months in Group C spiral cutting blade (not cut out) femoral head one cases; group C hip varus two cases. The whole segment intramedullary nailing) the occurrence of femoral shaft fracture in1(later renamed the femur. No cases of screw blade to cut out the femoral head phenomenon. Fractures quality evaluation results: excellent in69cases, good in31cases; not bad in14cases and poor in4cases.2. Senders hip joint score:A group of excellent and good rate was93.8%; Group B91.8%; group C61.9%.3. statistical analysis:A, B, and C, three groups of age, fracture type, quality of reduction was no significant difference (P>0.05), Senders hip score more significant difference (P<0.01).Conclusion1.PFNA is more safe and effective means of treatment of elderly intertrochanteric fracture, were satisfied.2.the spiral blade cutting the femoral head by patient age, type of fracture, and fracture and many other factors as the quality of reduction,"TAD" The higher the value, the greater the risk of the spiral blade cutting the femoral head.
