Ankle Joint

Ankle Joint

The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

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
手术技术手术技术

背景情况:

限制动力对齐全膝关节整形术 (rKA-TKA) 旨在防止与极端对齐相关的植入物失败.
目前的rKA-TKA技术通常依赖于计算机辅助手术 (CAS) 系统,增加成本和复杂性.
需要更简单的方法来实现在全膝关节整形术中有限的动力对齐.

研究的目的:

用传统的机械仪器来描述动力对齐全膝关节整形手术 (KA-TKA) 的手术技术.
为了证明rKA-TKA可以在没有计算机辅助设备 (CAS) 的情况下实现.
在机械KA-TKA中为准确的骨切割提供特定的测量和调整.

主要方法:

手术前的长腿X射线图或CT扫描用于测量横向远侧大腿角 (LDFA) 和中间近端角 (MPTA).
算术性-膝-脚角 (aHKA) 计算 (MPTA - LDFA) 并使用预定义的边界 (LDFA: 85°-93°,MPTA: 85°-90°,aHKA: 5° varus 到 3° valgus) 来确定骨切除的角度.
股骨骨切割的调整包括修改远部股骨表面厚度或使用可变角度切割指南. 骨切除术由外骨杆指导,将中间倾斜限制在5.5°以内.

主要成果:

描述的技术允许使用标准机械仪器精确执行受限制的动力调整.
在KA-TKA中实现所需的对齐参数不需要CAS.
该方法提供了一种可重复的方法,用于骨准备全膝关节关节整形术.

结论:

动力调整全膝关节整形手术 (KA-TKA) 可以使用机械仪器成功进行,为基于CAS的方法提供了经济有效的替代方案.
这种技术促进了有限的对齐,可能降低了植入物失败的风险.
描述的手术技术为外科医生提供了一种实际的方法,可以在没有先进技术的情况下实施KA-TKA.
