SUMMARY
Introduction. Scarf-Akin and Lapidus-Akin osteotomies are both well-known tech- niques used in managing hallux valgus deformities. The aim of this study is to deter- mine 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), inter- metatarsal 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 effec- tive 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% Confi- dence Interval [-14.42 to -6.68], p = 0.16), and AOFAS Hallux MTP-IP score (Scarf- Akin 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.
