A variety of metatarsal osteotomies has been described since the first report by Gernet in 1836. Many of these osteotomies were abandoned throughout the years. Because one procedure is not capable of correcting all types of hallux valgus deformities, an algorithm, as a guideline, is preferable. This article presents a choice of metatarsal osteotomies for correction of hallux deformities based on clinical and biomechanical research.
