The Analysis of PFNA- Ⅱ in the Treatment of Senile Intertrochanteric Fracture for 40 Cases

Abstract：Objective:To observe the clinical efficacy and safety of proximal femoral nail antirotation- Ⅱin the treatment of elderly intertrochanteric fracture.Methods:40 patients of senile intertrochanteric fractures treated with the PFNA-Ⅱ,18 males and 22 females.Age 65 to 80 years old,with an average of 75.5 years.The patients all were unilateral blunt cis intertrochanteric fracture.The Evans classification typeⅠ3 cases,typeⅡ7 cases,13 cases of typeⅢ,Ⅳ17 cases.Injury to operation 2-8 d,with an average of 4 d.The complications of diabetes was 10 cases,osteoporosis was 32 cases,10 cases of coronary heart disease, 12 cases of hypertension.Results:The mean operative time was (65.81±10.34)min,blood loss (130.81±45.02) ml,hospitalization time (11.33±2.77)d.The group 2 patients transfusion of 100 ml of blood transfusion in 2 patients,200 ml,and the remaining patients without blood transfusion.Fracture healing time of 7 to 14 weeks,an average of 10 weeks.Harris score 80 to 95 points the last follow-up,an average of 85.4 points.5 patients walking limb pain,but didn’t affect their daily lives.Two patients developed pulmonary infection,symptomatic treatment cured. Femoral head and neck did not occur shortened femoral neck cut,varus and internal fixation failure and other complications.Conclusion:PFNA-Ⅱis a safe and effective method for the treatment of senile intertrochanteric fracture,more in line with the the Asian bone anatomical characteristics,it worthy of clinical application.
