The aim of this study is to show the results of scaphotrapeziotrapezoid (STT) joint osteoarthritis treatment performing resurfacing arthroplasty with scaphoid anchorage.
An observational, descriptive and retrospective study was performed. Ten patients with isolated STT joint osteoarthritis were studied between 2013 and 2015. The mean follow-up time was 26months. Clinical results, functional and subjective scores were reviewed.
The patients were satisfied, achieving an average of 2.1 (0-3) on the VAS score and 16 (2 to 28) in the DASH questionnaire, and returning to work in the first three months post-surgery. Recovery of range of motion compared to the contralateral wrist was 96% in extension, 95% in flexion, 87% in ulnar deviation and 91% in radial deviation. The average handgrip strength of the wrist was 95% and pinch strength was 95% compared to the contralateral side. There were no intraoperative complications or alterations in postoperative carpal alignment.
Resurfacing arthroplasty is proposed as a good and novel alternative in treating isolated SST joint arthritis. Achieving the correct balance between the strength and mobility of the wrist, without causing carpal destabilisation, is important to obtain satisfactory clinical and functional results.
本研究旨在展示采用舟状骨锚定的表面置换术治疗舟大多角小多角（STT）关节骨关节炎的结果。
进行了一项观察性、描述性和回顾性研究。对2013年至2015年间10例孤立性STT关节骨关节炎患者进行了研究。平均随访时间为26个月。回顾了临床结果、功能和主观评分。
患者感到满意，视觉模拟评分（VAS）平均为2.1（0 - 3），上肢功能障碍评分系统（DASH）问卷评分为16（2至28），并在术后头三个月恢复工作。与对侧手腕相比，活动范围的恢复情况为：伸展96%，屈曲95%，尺偏87%，桡偏91%。手腕的平均握力与对侧相比为95%，捏力为95%。术中无并发症，术后腕骨对线无改变。
表面置换术被认为是治疗孤立性SST关节关节炎的一种良好且新颖的选择。在手腕的力量和活动度之间实现正确平衡，而不导致腕骨不稳定，对于获得满意的临床和功能结果很重要。
