概括

这项研究表明,全关节整形术 (TAA) 的跨管方法提供了卓越的植入物存活率,并改善了患者的治疗结果. 跨管TAA是末期关节关节炎的持久选择.

科学领域:

整形外科手术整形外科手术
生物医学工程生物医学工程

背景情况:

大多数全脚关节整形手术 (TAA) 程序使用前方方法.
齐默生物特 (Zimmer Biomet Trabecular Metal) 植入物独特地采用了一种横向跨管的方法.
这项研究提供了最大的跨管TAA结果中期分析.

研究的目的:

评估植入物存活率,临床结果和跨管TAA的X射线结果.
评估患者报告的结果指标 (PROM) 和放射性对齐.
分析与跨体TAA相关的不良事件和重新操作率.

主要方法:

130个脚 (122名患者) 的回顾性评估,随访时间至少为5年.
收集的PROMs:SF-12 (PCS/MCS),关节骨关节炎量表 (AOS),VAS疼痛.
放射性评估包括运动范围,对齐,沉降和周围假肢的放射性.

主要成果:

患者对SF-12 PCS (41.5),SF-12 MCS (54.9),VAS疼痛 (2.3),AOS疼痛 (19.1) 和AOS残疾 (28.5) 的高满意度.
成功纠正valgus/varus变形,改善了运动范围.
在中期随访时100%的植入物存活率;有限的周围假肢放射性,没有沉降或松动. 最常见的重新手术是中间沟沟脱bridement.

结论:

跨管TAA是一种有效和持久的治疗末期脚关节炎.
这种方法显示出极好的中期植入物存活率.
周围假肢有限的辐射发光度不会影响植入物稳定性.

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...
