Background

This study compared radiographic and functional patient outcomes of 1st MTP arthrodesis between hallux rigidus (HR) and hallux valgus (HV) cohorts.

Methods

A retrospective review was conducted at an academic medical center on patients who underwent 1st MTP arthrodesis during 2009–2021. In total, 136 patients (148 feet: HR=57, HV=47, combined=44) met the inclusion criteria of minimum three-month follow-up (mean=1.25 years, range=0.25–6.14 years). Data collection included patient-reported outcome measures (PROMs), radiographic markers, and complication and reoperation rates.

Results

PROMs improved overall, with HV patients significantly improving the least. The HR group had a significantly smaller improvement in HV angle (HR=−3.6, HV=−17, Combined=−15 p < .001), intermetatarsal angle (H=−0.16, HV=−2.8, Combined=−2.6 p < .001), and 1st-5th metatarsal width (HR=−0.98, HV=−4.6, Combined=−4.6, p < .001). Complication and reoperation rates did not differ by group.

Conclusion

Outcomes of 1st MTP arthrodesis does not appear to differ between diagnostic indications of hallux rigidus, hallux valgus, or both.

拇趾僵硬与拇趾外翻的第一跖趾关节固定术结果

背景

本研究比较了拇僵硬 (HR) 和拇外翻 (HV) 队列中第一次 MTP 关节固定术的影像学和功能患者结果。

方法

在学术医学中心对 2009-2021 年期间接受第一次 MTP 关节固定术的患者进行了回顾性研究。总共有 136 名患者（148 英尺：HR = 57，HV = 47，合并 = 44）符合至少三个月随访的纳入标准（平均 = 1.25 年，范围 = 0.25-6.14 年）。数据收集包括患者报告的结果测量 (PROM)、放射学标志物以及并发症和再手术率。

结果

PROMs 整体改善，HV 患者显着改善最少。HR 组在 HV 角（HR=-3.6，HV=-17，Combined=-15 p  < .001），跖骨间角（H=-0.16，HV=-2.8，Combined=-2.6 p ）方面的改善明显较小 < .001)，以及第 1-5 跖骨宽度（HR=−0.98，HV=−4.6，组合 =−4.6，p  < .001）。并发症和再手术率在各组之间没有差异。

结论

第一次 MTP 关节固定术的结果在拇趾僵硬、拇趾外翻或两者的诊断指征之间似乎没有差异。
