概括

六足动物的外部固定器精确地纠正了骨形,并延长了四肢. 虽然延长精度仍然很高,但复杂的角度校正可能需要调整.

科学领域:

整形外科手术整形外科手术
生物机械工程生物机械工程
肢体的重建肢体的重建

背景情况:

六足体外固定器系统可以进行多平面变形校正和肢体延长.
准确地纠正部形是恢复功能和对齐的关键.

研究的目的:

为了评估六足动物框架 (智能校正框架) 在纠正各种骨形的准确性.
在涉及延长,单平面校正或双平面校正的情况下评估框架的有效性.

主要方法:

用六足脚架治疗的54个部形的回顾性研究 (2015年1月 - 2021年1月).
根据纠正的类型,患者被分为四组:仅延长,延长与单平面纠正,单平面纠正,双平面纠正.
通过将实现的纠正/延长与手术前计划进行比较来确定准确性.

主要成果:

延长精度很高 (A组的96.3%±7.1%,B组的95.7%±5.9%).
角形变形的校正精度在80.2%±18.4% (D组) 到85.2%±13.9% (C组) 之间.
六个病例需要修复手术来完全纠正形,主要是在双平面纠正组.

结论:

六足动物的框架显示出高精度的小腿骨延长,同时形纠正的影响最小.
随着变形的复杂性增加,角度校正的准确性略有下降.
外科医生应该预见使用六足系统进行复杂的部形纠正的潜在重新编程需求.

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...
