概括

与传统的穿皮穿孔穿孔螺丝拉伸带 (PCST) 方法相比,通过合 anchors (TACS-SA) 技术的拉伸带布线显示出更好的生物机械稳定性和较快的下极骨骨折愈合.

科学领域:

整形外科手术整形外科手术
生物力学生物力学
创伤学创伤学创伤学

背景情况:

下极骨折 (IPFP) 带来了重大管理挑战.
传统的皮肤穿式螺丝拉伸带 (PCST) 技术具有很高的并发症率.
通过带螺丝和接 (TACS-SA) 穿过张力带的布线是一种需要验证的新替代方案.

研究的目的:

为了比较TACS-SA与IPFP的PCST固定的生物力学行为.
评估和比较TACS-SA和PCST技术之间的早期临床结果.

主要方法:

有限元分析 (FEA) 在压力下模拟膝盖屈曲,以评估骨折稳定性和固定强度.
分析了三种骨折模型 (TACS-SA,PCST与八的数字,PCST与零的数字).
一个由43名患者 (25 TACS-SA,18 PCST) 组成的临床队列被追溯分析了联合时间,ROM和功能评分.

主要成果:

与PCST变体相比,FEA对TACS-SA的骨折碎片稳定性和固定强度优越 (p <0.05).
TACS-SA组比PCST组早得多地实现了射线统一 (p < 0.05).
在骨结合期,ROM,Böstman分数,KOOS分数或组之间的延伸滞后方面没有发现显著差异.

Fractures: Bone Repair

Fractures: Bone Repair

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
