TMT-1 arthrodesis is an established method in hallux valgus surgery, but it is technically demanding and typically calls for a period of postoperative immobilization.
In this cohort study, initial experience with a plantar plate is described. 58 patients (59 arthrodesis) were included.
The mean duration of protected full weight bearing was 7 weeks. 94.12% patients were satisfied with the results, bony union was achieved in 98.31%. The Foot Function Index improved by 33 to a mean of 8 (p<.001). The postoperative Mayo Clinic Forefoot Score was excellent in 47.04 and good in 47.04%. The mean hallux valgus angle improved by 24.4-13.2° (p<.001). The mean first intermetatarsal angle improved by 11.2-5.2° (p<.001).
Initial experience with this form of fixation appears to provide suitable stability, allow early-protected weight bearing, with an acceptable level of complications.
TMT-1 融合术是治疗拇外翻的一种成熟方法，但技术要求较高，通常需要术后固定一段时间。
本队列研究描述了一种跖板的初步应用经验。共纳入 58 例患者（59 例融合术）。
保护性完全负重的平均持续时间为 7 周。94.12%的患者对结果满意，骨愈合率为 98.31%。足部功能指数（Foot Function Index）改善 33 分，平均为 8 分（p<.001）。术后 Mayo 前足评分优秀者占 47.04%，良好者占 47.04%。拇外翻角平均改善 24.4-13.2°（p<.001）。第一跖骨间角平均改善 11.2-5.2°（p<.001）。
这种固定方式的初步经验似乎提供了足够的稳定性，允许早期保护性负重，并发症发生率可接受。
