A comparative study on imaging parameters of Chevron combined with Akin osteotomy and Scarf combined with Akin osteotomy for the correction of hallux valgus in patients at different ages

Objective:To study the imaging parameters of Chevron combined with Akin and Scarf combined with Akin for the correction of hallux valgus in patients of different ages.Methods:Eighty patients(152 feet)with hallux valgus who underwent Chevron combined with Akin and Scarf combined with Akin in our hospital were randomly selected.The patients were divided into young and middle-aged groups.Measure the hallux valgus angles(HVA),distal metatarsal articular angle(DMAA)and intermetatarsal angles(IMA)with professional X-ray measurement software and then reseach the effect of two the operation methods.Results:Young group:Chevron combined with Akin and Scarf combined with Akin significantly improved HVA and IMA,the difference had statistical significance(P<0.05),but the improvement effect of the two groups was similar,and the difference had no statistical significance(P>0.05).The improvement effect of the two groups on DMAA in young patients was not significant,and the difference had no statistical significance(P>0.05);Middle-aged group:Chevron combined with Akin and Scarf combined with Akin also significantly improved HVA and IMA(P<0.05),but the improvement effect of the two groups was similar,and the difference had no statistical significance(P>0.05).Chevron combined with Akin significantly improved DMAA in middle-aged and elderly patients,and the difference had statistical significance(P<0.05).Scarf combined with Akin did not significantly improve DMAA in middle-aged and elderly patients,and the difference had no statistical significance(P<0.05).Conclusion:Both Chevron combined with Akin and Scarf combined with Akin are effective and widely used.Chevron combined with Akin was able to improve DMAA in middle-aged and elderly patients.Therefore,Chevron combined with Akin is recommended for middle-aged and elderly patients with hallux valgus.

The Radiological Outcome of Surgical Correction of Hallux Valgus with Combined Scarf and Akin Osteotomies

Background: Hallux valgus deformity is one of the most common chronic and progressive foot deformities. Surgical correction of the deformity plays a central role in the treatment of symptomatic hallux valgus. However, more than one hundred different surgical techniques have been described. Objective: To assess the radiological outcome of hallux valgus surgical correction using a scarf and akin osteotomies. Materials and methods: A cross-sectional hospital-based study was conducted on 25 adult patients (36 feet). Twenty-two females and two males with hallux valgus were treated with surgical correction using a scarf and akin osteotomies. All candidates were kept on regular postoperative, scheduled clinical follow-up programs for one year and assessed radiologically. Results: Twenty-five patients (36 feet) were included in this study. The hallux valgus angle significantly shifted to the normal range (less than 15°) after surgery, and the inter-metatarsal angle also improved to the normal range (less than 9°). Conclusion: Using scarf and akin osteotomies in treating moderate and severe hallux valgus deformity provides the satisfactory radiological outcomes in form of decreasing hallux valgus angle and inter-metatarsal angle.
