Effect of lengthened proximal femoral nail anti-rotationin in the treatment of Seinsheimer type Ⅴ subtrochanteric fracture of femur
Objective To investigate the clinical effect of lengthened proximal femoral nail anti-rotation(PFNA)in the treatment of Seinsheimer type Ⅴ subtrochanteric fracture of femur.Methods The clinical data of 21 patients with Seinsheimer type Ⅴ subtrochanteric fracture of femur treated by closed reduction or limited incision wire binding combined with lengthened PFNA in our hospital from January 2020 to August 2022 were retrospectively analyzed.The fracture healing status,treatment effect,postoperative complications and Harris score of hip joint function at the last postoperative follow-up of patients were recorded and evaluated.Results All patients were followed up for 6 to 12 months,and the fractures healed well.There were no cases of internal fixation breakage or cutting,no cases of vascular injury,and 1 case of ectopic ossification.At the last follow-up,the hip joint function was excellent in 15 cases,good in 4 cases and fair in 2 cases,with an excellent and good rate of 90.48％.Conclusion Lengthened PFNA can effectively treat Seinsheimer type Ⅴ subtrochanteric fracture of femur,and minimally invasive steel wire cerclage is performed when the closed reduction is not ideal,which has the advantages of less trauma,fast fracture healing,fewer postoperative complications and good recovery of hip joint function,and is worthy of clinical promotion and application.
