Abstract

Introduction. Scarf-Akin and Lapidus-Akin osteotomies are both well-known techniques used in managing hallux valgus deformities. The aim of this study is to determine the difference between Scarf-Akin and Lapidus-Akin osteotomies, examining both radiological and patient reported outcomes. Methods. Articles were obtained using the PubMed and ScienceDirect database. A total of 31 articles were included in the final review. Hallux valgus angle (HVA), intermetatarsal angle (IMA), and American Orthopedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal (AOFAS Hallux MTP-IP) score were analyzed using random-effects meta-analysis. Results. A total of 1,437 feet and 171 feet underwent Scarf-Akin and Lapidus-Akin osteotomies, respectively. Both Scarf-Akin and Lapidus-Akin osteotomies were effective in improving HVA, IMA, and AOFAS Hallux MTP-IP score (p < 0.00001). No significant differences were found in comparing Scarf-Akin and Lapidus-Akin outcomes in HVA (Scarf-Akin Mean Difference:-22.16, 95% Confidence Interval [-24.72 to-19.60], Lapidus-Akin Mean Difference:-21.32, 95% Confidence Interval [-25.75 to-16.88], p = 0.75), IMA (Scarf-Akin Mean Difference:-7.73, 95% Confidence Interval [-8.55 to-6.91], Lapidus-Akin Mean Difference:-10.55, 95% Confidence Interval [-14.42 to-6.68], p = 0.16), and AOFAS Hallux MTP-IP score (ScarfAkin Mean Difference: 35.83, 95% Confidence Interval [29.65-42.01], Lapidus-Akin Mean Difference: 28.90, 95% Confidence Interval [18.37-39.44], p = 0.27). Conclusions. No statistically significant difference was found between Scarf-Akin and Lapidus-Akin osteotomies in HVA, IMA, and AOFAS Hallux MTP-IP score. Further research is needed especially in examining Lapidus-Akin osteotomy due to its low quantity of published studies compared to Scarf-Akin osteotomy. © 2025, EDRA S.p.A. All rights reserved.
