股骨近端防旋髓内钉治疗股骨转子间骨折的临床应用

The minimally invasive surgery on intertrochanteric fractures with proximal femur nail antirotation

目的探讨防旋型股骨近端髓内钉(PFNA)治疗股骨转子间骨折的临床疗效。方法根据AO分型,其中A1型患者6例,A2型患者29例,A3型患者8例,所有患者均微创植入PFNA。结果术后摄X线按Garden标准评价骨折复位质量,优24例,良14例,可3例,差2例,无患者死亡,所有患者骨折愈合效果良好。结论PFNA治疗股骨转子间骨折固定可靠,初期临床疗效满意,若骨折波及转子下及股骨干上部,有的需辅助小切口复位,选用加长型PFNA,并且术后负重时间相应延长。

Objective To investigate the anti-rotation proximal femoral nail （PFNA） clinical efficacy for the treatment of intertrochanteric fractures. Methods According to the AO classification, including six cases of patients with type A1, A2 patients with 29 cases the A3 of patients with type 8 cases, all patients were minimally invasive implantation PFNA. Results postoperative X-ray taken by Garden criteria to evaluate fracture reduction quality, excellent in 24 cases, good in 14 cases, in 3 cases and poor in 2 cases, no patient deaths, all fracture healing in patients with good results. Conclusion PFNA treatment of intertrochanteric fracture fixation and early clinical results were satisfactory, if the fracture spread to the upper part of subtrochanteric and femoral shaft, some need to reset assisted small incision choice lengthened PFNA, and postoperative weight-bearing time is extended accordingly.
