评估TMTAA的中期临床和放射性结果.
在至少5年的随访期评估生存率和不良事件.

主要方法:

分析了83个脚 (81名患者),平均随访时间为6.3年.
患者报告的结果指标 (PROM) 包括SF-12,关节骨关节炎量表 (AOS) 和疼痛视觉模拟量表 (VAS).
放射性评估包括运动范围 (ROM) 和冠状/形对齐;不良事件使用加拿大整形足和脚协会重复编码系统 (CROCS) 追踪不良事件.

主要成果:

手术前的冠状元形 (形/形) 被 postoperatively 纠正到中性对齐.
在手术后的脚ROM平均为17.8°的背部曲和21.8°的脚部曲.

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...
