摘要:

背景:防旋型股骨近端髓内钉有精确的定位装置,骨折手术置入时可采用小切口闭合复位,创伤小,对骨折端血运破坏少,符合骨折治疗的“BO”理论和微创手术原则。
目的:回顾分析防旋型股骨近端髓内钉治疗老年患者股骨转子间骨折的临床疗效。
方法:共纳入48例股骨转子间骨折患者,其中男30例,女18例;年龄70-86岁,平均77.3岁;骨折AO分型,31-A1型12例,31-A2型23例,31-A3型13例。均采用闭合复位,防旋型股骨近端髓内钉置入内固定治疗。定期随访了解骨折愈合情况及内固定装置的位置,根据Harris评分评价治疗后髋关节功能。
结果与结论:48例均骨性愈合,平均愈合时间4.5个月。所有股骨转子间骨折均获得满意复位,防旋型股骨近端髓内钉位置满意,无内固定物松动及脱出、固定失效、股骨头缺血性坏死、髋内翻畸形等并发症发生。末次随访髋关节功能Harris评分显示,优31例,良14例,可3例,优良率为93.7%。提示防旋型股骨近端髓内钉治疗老年患者股骨转子间骨折符合生物力学要求,安全有效。

Abstract:

BACKGROUND: Proximal femoral nail antirotation has a precise positioning device. Small incision closed reduction was used during implantation after fracture. This method induces few traumas and less damage to blood transportation at the fracture end, and is accorded with “BO” theory and the principle of small invasive operation for treatment of fracture.
OBJECTIVE: To retrospectively analyze the clinical therapeutic effects of proximal femoral nail antirotation for intertrochanteric fractures in senile patients.
METHODS: A total of 48 patients with intertrochanteric fractures were enrolled, including 30 males and 18 females, aged 70-86 years old, averagely 77.3 years. According to AO classification, there were 12 cases of 31-A1, 23 cases of 31-A2 and 13 cases of 31-A3. Closed reduction and proximal femoral nail antirotation were utilized. Fracture healing and the position of the device were understood by regular follow-up. Functional recovery of the hip joint was evaluated using Harris score after surgery.
RESULTS AND CONCLUSION: Bone union was observed in 48 cases, averagely 4.5 months. Satisfactory reduction was obtained in all intertrochanteric fractures. The position of the nail was satisfactory. No complications appeared such as loosing, prolapse, ineffective fixation, avascular necrosis of the femoral head and coxa vara malformation. During final follow-up, Harris score revealed excellent in 31 cases, 14 in good and 3 in average, with an excellent and good rate of 93.7%. Results indicated that proximal femoral nail antirotation for intertrochanteric fractures in elderly patients was in accordance with the requirement of biomechanics, and was safe and effective.
