Abstract: Objective To introduce the combination of two kind of minimally invasive osteotomy in treatment of severe hallux valgus.Methods The clinical data of 2123 patients（3865 feet）who had hallux valgus between January 2007 and June 2017 were reviewed.There were 2082 females and 41 males with an average age of 56.39 years.Among these patients，207 patients（253 feet）had severe hallux valgus.124 patients（163 feet）who had severe hallux valgus had received the combination of two kind of minimally invasive osteotomy which in the first proximal phalanx and metatarsal.83 patients（90 feet）who had severe hallux valgus had just received one kind of minimally invasive osteotomy which in the first metatarsal.1916 patients（3612 feet）who had mild and moderate hallux valgus had just received one kind of minimally invasive osteotomy which in the first metatarsal.Results All patients were followed for 3～30 months.In the combined surgery group，HVA after surgery was（2.8±1.11）°，IMA after surgery was（5.68±1.62）°.The difference between combined surgery group and uncombined surgery group has statistical significance（P=0.044）in HVA after surgery among severe hallux valgus patients.In the combined surgery group，84.67% of patients had excellent results，14.52% good，and 0.81% bad.In the uncombined surgery group of severe hallux valgus，79.52% of patients had excellent results，19.82% good，and 1.20% bad.In the uncombined surgery group of mild and moderate hallux valgus，82.83% of patients had excellent results，17.07% good，and 0.10% bad.Conclusion the combination of two kind of minimally invasive osteotomy in treatment of severe hallux valgus had the better HVA，less complication，higher satisfaction degree after surgery.
