股骨近端防旋髓内钉治疗股骨反转子间骨折

Proximal femoral nail antirotation for the treatment of reverse intertrochanteric fractures

目的评估股骨近端防旋髓内钉(PFNA)治疗股骨反转子间骨折的临床疗效。方法 21例反转子间骨折采用PNFA内固定,牵引床牵引复位。不暴露骨折断端,微创植入PFNA。结果 21例均获随访,时间12～36个月。骨折均愈合,愈合时间13～28周。1例诉髋部疼痛,1例10°内翻愈合,2例双下肢不等长;无螺钉切割及内固定失败等并发症发生。结论 PFNA是治疗股骨反转子间骨折的有效方法,软组织损伤小,固定稳定,并发症少。

Objective To evaluate the clinical effect of proximal femoral nail antirotation（PFNA） for the treatment of reverse intertrochanteric fractures. Methods 21 cases of reverse intertrochanteric fractures were treated with PFNA fixation. All cases were reduced through longitudinal traction on the traction table, without exposing of the fracture section during the operation. Results 21 cases were followed up for 12 - 36 months. All fractures healing time was 13 -28 weeks. One patient complained of hip pain. One case healed up with 10° varus deformity. Two cases had limb length discrepancy. No complications such as cut-out or breakage of the implants occurred. Conclusions PFNA is an effective treatment method for reverse intertrochanteric fractures with less tissue damage, more stable fixation and less complications.
