First metatarsophalangeal arthrodesis outcomes for hallux rigidus versus hallux valgus

摘要

? 2022 European Foot and Ankle SocietyBackground: 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. Level of Evidence: Level III, Retrospective cohort study
