加长型股骨近端防旋髓内钉治疗老年股骨转子间骨折OA

Objective To explore the efficacy of the extended proximal femoral nail anti-rotation(PFNA)in the treatment of femoral intertrochanteric fracture in the elderly.Methods Sixteen elderly patients with fermoral inter-trochanteric fractures were treated with extended PFNA.The fracture healing time and the occurrence of complications were recorded,and the therapeutic effect was evaluated using the Harris hip function assessment criteria.Results All patients were followed up for10～38 months.All fractures healed within 12～28 weeks.No complications such as internal fixation fracture,re-fracture,incision infection,and coxa varus or valgus deformity occurred.After the op-eration,one case had a mild resection of the anti-screw,the bed rest time was prolonged and no special treatment was given.At the last follow-up,the therapeutic effect was evaluated using the Harris scoring standard:The result was excellent in 10 cases,good in 5 cases,fair1 case,and the excellent and good rate was 15/16.Conclusions The extended PFNA in the treatment of femoral intertrochanteric fracture in the elderly has the advantages of less trauma,anti-rotation,good fixation effect and fewer complications,which is conducive to fracture healing and the recovery of limb function.
