OBJECTIVE: The aim of this study was to analyze the effect of Scarf and Chevron combined with Akin on a postoperative balance of patients with moderate to severe foot bunion. PATIENTS AND METHODS: One hundred (100 feet) patients with moderate to severe bunion cysts treated at our hospital from January 2019 to January 2022 were retrospectively selected as subjects and divided into 2 groups according to their surgical procedure. The control group received Scarf combined with Akin, and the study group received Chevron combined with Akin. Oxidative stress mediators [late oxidized protein product (AOPP), lipid peroxide (LPO)], inflammatory factors [interleukin-1ß (IL-1ß), procalcitonin (PCT)], Hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal joint angle (DMAA) Angle, ankle-hind foot American Orthotic Foot and Ankle Association (AOFAS) score, pain visual analog scale (VAS) score and balance Berg Balance Scale (BBS) score were compared between the two groups before and after surgery. The effectiveness and safety of the operation were compared. RESULTS: The levels of AOPP and LPO in the study group decreased most significantly, t=1.081 and 10.850, p=0.001; the levels of IL-1ß and PCT in the study group increased most significantly, t=16.970 and 12.260, p=0.001; the indexes of HVA, IMA, and DMAA in the study group increased significantly, t=11.890, 11.550, and 12.670, p=0.001; the AOFAS and BBS scores in the study group increased significantly, while the VAS score in the study group decreased significantly, t=14.760, 13.580, 5.994, p=0.001; the total effective rate of treatment in the study group was the highest, X²=6.960, p=0.00; the total incidence of complications in the study group was the lowest, X²=1.834, p=0.175. CONCLUSIONS: Chevron combined with Akin is more effective than Scarf combined with Akin in treating moderate to severe foot bunion, the former is more minimally invasive and has a better effect in promoting postoperative balance recovery.
