摘要:

背景:股骨近端抗旋髓内钉髓内固定承受应力的轴心比动力髋螺钉、动力髁螺钉向内移,抗疲劳能力增大,具备抗内翻支撑和防止近端骨折块旋转的功能,对骨折是否稳定要求不高,因此适用于不稳定性骨折。
目的:评价股骨近端螺旋刀片抗旋髓内钉置入治疗老年骨质疏松性股骨转子间骨折的效果。
方法:回顾性分析使用股骨近端螺旋刀片抗旋髓内钉置入内固定治疗股骨转子间骨折44例临床资料。其中男性20例,女性24例,年龄63~86岁。Evans-JensenⅡ型骨折3例、Ⅲ型8例、Ⅳ型10例、Ⅴ型23例。随访12个月,记录各型骨折术后并发症的发生情况、临床愈合时间及功能评分。
结果与结论:44例平均5个月获得骨性愈合,除2例早期负重出现髋内翻畸形,其他所有病例未出现股骨近端再骨折、股骨头缺血坏死、断钉、感染等并发症。根据Harris髋关节评分,优良率为96%。说明股骨近端螺旋刀片抗旋髓内钉置入治疗各型股骨转子间骨折效果较好,尤其适用于粉碎性或骨质较差的骨质疏松老年股骨转子间骨折,具有创伤小,操作简单,固定可靠,骨量丢失少等优点。

Abstract:

BACKGROUND: The axis under stress of proximal femoral nail anti-rotation blade (PFNA) is inward shifted compared with dynamic hip screw (DHS), dynamic condylar screw (DCS), thereby increasing resistance to fatigue, with the support and the prevention of anti-varus rotation and thus less demanding on the stability of fractures. It has been used in unstable fracture.
OBJECTIVE: To evaluate the effect of PFNA in the treatment of the elderly osteoporotic femoral intertrochanteric fracture.
METHODS: A total of 44 cases of femoral intertrochanteric fracture treated by PFNA were retrospectively analyzed, including 20 males and 24 females aged 63-86 years. According to the Evans-Jensen classification, there were 3 cases of type Ⅱ, 8 of type Ⅲ, 10 of type Ⅳ, and 23 of type Ⅴ. The patients were followed up for 12 months. The incidence of postoperative complications, healing time and functional score were recorded.
RESULTS AND CONCLUSION: All the 44 patients obtained fracture healing in average of 5 months. No complications such as proximal femoral refracture, femoral head avascular necrosis, or stub nail, were detected, except for two cases of coax vara due to the early time weight-load. According to Harris hip score, the excellent and good rate was 96%. Results show that PFNA is an effective therapy for femoral intertrochanteric fracture, especially for comminuted fractures or the aged osteoporosis fractures. It has some advantages, minimal invasion, simple operation, solid internal fixation, and little bone loss.
