文题释义:
新型股骨近端髓内钉(InterTan):为施乐辉公司为治疗股骨近端骨折设计的第4代髓内固定系统,联合交锁的双钉模式避免了传统重建钉产生的“Z-效应”,又提供了可控性的滑动加压效果,InterTan可以说是整合了TRIGEN第3代髓内钉和IMHS髋部加压髓内钉两大系统优点的第4代髓内固定产品。
股骨近端防旋髓内钉:主要针对老年骨质疏松患者研制而成。其具有良好的生物力学优势,主钉外翻弧度设计不仅有利于主钉插入髓腔,而且减少对骨髓腔内的血运破坏,降低术中失血量。螺旋刀片提供与股骨头骨质较大的接触面,加强旋转及角度的稳定性;螺旋刀片具有较强的抗切出能力,有学者研究发现螺旋刀片的抗切出能力约2倍于普通拉力螺钉。螺旋刀片打入后,能够压实股骨头疏松的骨质,骨量丢失少,不仅能提高螺旋刀片的稳定性,而且能够防止旋转、塌陷,明显提高了与周围骨质的密度和把持力。 
 
摘要
背景:目前对老年股骨转子间骨折的手术治疗多采用髓内固定及髓外固定两种方式。髓内固定以其操作简单,创伤小,并发症少等优点已经成为治疗老年股骨转子间骨折的金标准。
目的:探讨应用动力髋螺钉、股骨近端防旋髓内钉、新型股骨近端髓内钉(InterTan)3种内固定方法修复老年股骨转子间骨折的临床疗效。
方法:回顾性分析2010年1月至2016年1月南方医科大学珠江医院骨科收治120例股骨转子间骨折患者的临床资料,随机分为3组,其中动力髋螺钉组40例,股骨近端防旋髓内钉组60例,InterTan组20例。记录各组患者手术时间、术中出血量、切口长度、住院时间、负重时间、骨折愈合时间、髋关节功能Harris评分、术中术后并发症,并进行组间对比。
结果与结论:①手术时间、术中出血量、切口长度比较,InterTan组、股骨近端防旋髓内钉组优于动力髋螺钉组,差异均有显著性意义(P < 0.05),InterTan组与股骨近端防旋髓内钉组差异无显著性意义(P > 0.05);②负重时间、骨折愈合时间、术后1个月Harris评分方面,InterTan组优于股骨近端防旋髓内钉组、动力髋螺钉组,股骨近端防旋髓内钉组又优于动力髋螺钉组,差异均有显著性意义(P < 0.05);③3组在住院时间、术后6,12个月髋关节功能Harris评分方面比较,差异无显著性意义(P > 0.05);④InterTan组、股骨近端防旋髓内钉组术中术后并发症发生率低于动力髋螺钉组,差异有显著性意义(P < 0.05);⑤综上,股骨近端防旋髓内钉、InterTan相比动力髋螺钉系统具有创伤小、操作简单、术后恢复快、并发症少等特点,对股骨转子间骨折的治疗显示出良好的修复效果。相比股骨近端防旋髓内钉,InterTan系统骨折复位固定及稳定性更好,骨折临床愈合时间更短,具有更好的生物力学优势。

Abstract:

BACKGROUND: At present, the treatment methods for intertrochanteric fracture of the femur in the aged are in two ways: Intramedullary fixation and extramedullary fixation. The advantages of intramedullary fixation with simple operation, small trauma and few complications have become the gold standard for the treatment of intertrochanteric fracture in the femur in the aged.

OBJECTIVE: To explore the clinical curative effects of three internal fixation methods: dynamic hip screw, proximal femoral nail antirotation, and intramedullary nail InterTan in the treatment of intertrochanteric fractures of the femur in the aged. 
METHODS: A retrospective analysis of 120 cases of intertrochanteric fractures from January 2010 to January 2016 was performed. The patients were randomly divided into dynamic hip screw group (n=40), proximal femoral nail antirotation group (n=60) and InterTan group (n=20). The operative time, intraoperative blood loss, incision length, hospitalization time, postoperative weight-bearing time, fracture healing time, Harris score, and intraoperative and postoperative complications were recorded and compared among the three groups.
RESULTS AND CONCLUSION: (1) Operative time, intraoperative blood loss, and incision length were significantly better in the InterTan group and proximal femoral nail antirotation group than in the dynamic hip screw group (P < 0.05). Above indexes were not significantly different between InterTan and proximal femoral nail antirotation groups (P > 0.05). (2) Postoperative weight-bearing time, fracture healing time, and Harris score one month after operation were significantly better in the InterTan group than in the proximal femoral nail antirotation and dynamic hip screw groups; above indexes were better in the proximal femoral nail antirotation group than in the dynamic hip screw group (P < 0.05). (3) Hospitalization time and Harris score at 6 and 12 months after operation were not significantly different among the three groups (P > 0.05). (4) The incidence rate of intraoperative and postoperative complications was significantly lower in the InterTan group and proximal femoral nail antirotation group than in the dynamic hip screw group (P < 0.05). (5) In summary, compared with dynamic hip screw system, proximal femoral nail antirotation and InterTan system are characterized by small trauma, simple operation, quick recovery, and fewer complications, and show good clinical therapy in the treatment of intertrochanteric fracture. Compared with proximal femoral nail antirotation system, InterTan system shows better fracture reduction and stability, shorter healing time, and better biomechanical advantages.
