Introduction: Hallux valgus is the most common disorder of the first toe. It causes pain, functional impairment, and alters gait patterns. Mild to moderate deformities are tipically corrected with distal osteotomies of the first metatarsal, such as the chevron osteotomy, a safe procedure, but not without complications. The objectives of this study were to determine the incidence of pseud-arthrosis following this osteotomy and report our therapeutic method, follow-up, and outcomes. Materials and Methods: A retrospective multicenter study was carried out, which included patients operated on between 2009 and 2018. A total of 1156 chevron osteotomies were evaluated as a treatment for mild to moderate hallux valgus in 1017 patients (age range 16 -83 years; average 57.5 years) performed by 4 experienced surgeons. The inclusion criterion was that the patient had imaging studies compatible with pseudarthrosis six months after surgery. Results: We evaluated five patients who met our criterion. The average AOFAS (American Orthopedic Foot and Ankle Society) scores were 51 before hallux valgus treatment and 87.8 after pseudarthrosis treatment. Conclusion: The incidence of pseudarthrosis was 0.4% in the distant postoperative period. Our approach and treatment of pseudarthrosis achieved excellent clinical and functional improvements in all operated patients.
