概括

半针断裂发生在使用Orthex六足脚架的儿科下肢形纠正中,与复杂的病例和特定配置相关. 泰勒空间框架 (TSF) 没有出现任何断裂.

科学领域:

整形外科手术整形外科手术
儿科整形医生儿科整形医生
生物机械工程生物机械工程

背景情况:

多平面外部固定器对于纠正复杂的儿科腿部形至关重要.
在使用Orthex六脚架的4个案例中观察到半针断裂.

研究的目的:

确定导致儿科下肢形纠正中半针断裂的因素.
为了比较Orthex和泰勒空间框架 (TSF) 六足系统之间的变形校正特性.

主要方法:

在2012年至2022年期间接受Orthex或TSF框架治疗的儿科患者的回顾性评估.
框架配置,固定方法,实现的校正和治疗持续时间的比较.

主要成果:

四个Orthex框架经历了近接半针断裂;零个TSF框架没有.
骨架框架与年轻的患者,更近距离的半针,非标准的配置和更长的治疗时间有关.
两张照片之间在长度增长,角度校正或愈合指数方面没有发现显著差异.

结论:

这项研究是第一个报告半针断裂与多平面框架在儿科下肢形纠正.
钉子断裂似乎是多因素的,与变形纠正和特定框架配置的复杂性增加有关.
在Orthex和TSF组之间患者群体和框架设置的差异使直接因果关系的归因复杂化.

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...
