概括

在全膝关节整形术修订中,冠状元位不整是不常见的,用于无菌部松动. 大多数患者有正确的对齐,这表明其他因素有助于松动.

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
医疗成像医学成像

背景情况:

冠状元错位和不良的植入物定位是膝盖全关节整形术 (TKA) 后无菌骨松动的潜在风险因素.
之前的研究提出了关于对齐和植入物松动之间的关联的相互矛盾的证据.
对TKA的动力调整技术越来越感兴趣.

研究的目的:

调查在接受无菌松修复手术的患者中四肢和部件冠状元不对齐的发生率.
评估TKA中冠状元对齐参数和无菌骨松之间的关系.

主要方法:

一项回顾性队列研究确定了73名患者,对无菌骨松进行了修订.
从初级TKA中分析了手术前和手术后的放射图,以确定冠状四肢和部件的对齐.
适当的对齐被定义为中性或肢对齐和部植入物位置在中性机械轴的3°以内.

主要成果:

只有5.5%的患者 (4/73) 呈现出超过3°的小腿部部部件向对齐.
94.5%的患者 (69/73) 拥有正确对齐的部植入物.
平均肢体冠状元对齐为3°,8.2% (6/73) 的患者显示冠状元肢体对齐.

结论:

肢体和部植入物错位在用于无菌部松动的TKA修订中不常见.
大多数经过修订的案例都属于已确定的"安全"调整参数.
除了冠状元对齐之外的因素可能在无菌部松的病因中发挥更重要的作用.

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...
