Purpose: This study aimed to detect the effect of a modified chevron osteotomy on hallux valgus (HV) deformity at five-year follow up.
Methods: Twenty patients with symptomatic HV who underwent modified chevron osteotomy between June 2014 and January 2016 were included in the present study. The minimum follow-up duration was five years. Each patient was evaluated preoperatively, six weeks postoperatively and five years postoperatively using the visual analog scale (VAS) pain score, the American Orthopedic Foot & Ankle Society (AOFAS) score and cosmetic and radiological outcomes.
Results: The AOFAS score improved from 54.40 ( ± 4.58) preoperatively to 94.30 ( ± 2.15) six weeks postoperatively (p < 0.001) and 96.95 ( ± 1.54) five years postoperatively (p < 0.001). The VAS scores decreased from 6.30 ( ± 1.17) preoperatively to 0.15 ( ± 0.37) five years postoperatively (p < 0.001). The mean intermetatarsal angle improved from 16.00° ( ± 2.20°) preoperatively to 4.15° ( ± 1.22°) six weeks postoperatively (p < 0.001) and 4.40° ( ± 1.39°) five years postoperatively (p < 0.001). The mean HV angle also improved, from 32.70° ( ± 5.34°) preoperatively to 4.80° ( ± 1.40°) six weeks postoperatively (p < 0.001) and 5.20° ( ± 1.32°) five years postoperatively (p < 0.001). The cosmetic results were either excellent or good in 19 patients (95%). There was no recurrence in this study during the five postoperative years.
Conclusion: A modified chevron osteotomy can achieve successful correction of moderate-to-severe HV, with excellent outcomes at five-year follow up.

Researchers have modified PLA materials to enhance their mechanical properties and meet the clinical requirements. However, the strength and stiffness of PLA are still significantly lower than those of metals. Building on the established chevron clinical procedure and considering the mechanical characteristics of PLA screws, we devised a modified chevron osteotomy (MCO) based on a load-reducing structure with the aim of reducing the load on the screws.

: Hallux valgus is a common forefoot disorder with hundreds of proposed management techniques. Distal chevron osteotomy with a modified McBride procedure has been traditionally recommended for mild hallux valgus because of its simple and less invasive nature with fewer complications, faster recovery, and reliable outcomes. In recent years, the indications for this procedure have expanded to include hallux valgus with severe deformities.

In this study, we have developed a nanostructured electrochemical sensor based on modified graphene nanoribbons tailored for the analysis of nonelectroactive compounds via a surface competitive assay. Stigmasterol, a nonelectroactive phytosterol, was selected as a representative case. Chevron-like graphene nanoribbons, chemically synthesized, were immobilized onto glassy carbon electrodes and covalently functionalized to allow the on-surface formation of a supramolecular complex.

Objective: To explore early effectiveness of modified minimally invasive Chevron-Akin (MICA) osteotomy in the treatment of moderate to severe hallux valgus.
Methods: A clinical data of 49 patients (61 feet) with moderate to severe hallux valgus, who met the selection criteria between December 2019 and October 2022, was retrospectively analyzed. There were 7 males (8 feet) and 42 females (53 feet) with an average age of 38.

Percutaneous hallux valgus correction is gaining popularity with foot and ankle surgeons. Various studies have found that the percutaneous approach has increased patient satisfaction and outcomes. The technique of the procedure has some variability with the geometry of the distal osteotomy being the most scrutinized.
