概括
在修复全膝关节整形术 (TKA) 中,用于形金属 (TM) 支的骨部件的迷你碎片螺丝固定显示出出色的短期存活率,即使骨库有限和感染率高.
科学领域:
- 整形外科手术 整形外科手术
- 生物材料工程是生物材料的工程.
- 关节塑形研究研究
背景情况:
- 修复全膝关节整形手术 (TKA) 具有有限的骨骨库的挑战,可能会损害组件的固定.
- 带形金属 (TM) 支持的形部件为长期固定提供了解决方案,但当前的接等方法存在局限性.
- 为了解决这些局限性,开发了一种新的迷你碎片螺丝固定技术.
研究的目的:
- 为了评估多孔TM支持的状骨部件的存活率,用微碎片螺丝固定在TKA患者的修订中,他们的状骨库存有限.
- 评估与此固定方法相关的放射性稳定性和重新操作率.
主要方法:
- 在2020年3月至2022年5月期间,在TKA的修订过程中,在TKA的修订过程中,通过微型碎片螺丝贴上22个TM支的骨进行了回顾性审查.
- 评估患者的人口统计,TM支持的骨存活率,放射性松和TKA重新手术.
- 平均随访时间为3年.
主要成果:
- 尽管有高患病率的周围假肢关节感染 (PJI) 史 (82%) 和有限的手术前骨厚度 (平均7.6毫米),但由于感染,只有一个TM支持的骨被移除.
- 所有幸存的TM支持的骨部件都表现出放射性稳定性.
- 由于各种原因,包括感染,部件松动,骨折和骨突起,九个TKA需要重新手术;然而,TM支持的部件被认为是固定的,并在手术期间保留.
结论:
- 用小碎片螺丝固定的TM支的骨部件在修复TKA中表现出优异的短期生存能力,骨库有限.
- 为了证实中长期结果,需要进行更多的随访期和更高水平的证据的进一步研究.

01:27Fractures: 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 procedure...

Frames are essential components of various mechanical and structural systems used daily. These structures are known for their stability and ability to bear heavy loads. A frame is constructed using two-force and multi-force members, interconnected using pin joints. In contrast, trusses are made entirely of two-force members.
Frames are versatile and widely used in various applications such as structural supports for beams and columns, automobile chassis construction, and in the construction...

01:24Frames: Problem Solving I
Consider a jib crane with an external load suspended from the pulley. The dimensions of the crane members are shown in the figure. A systematic analysis of the frame structure is required to determine the reaction forces at the pin joints, assuming that the pulleys are frictionless.
