Introduction: Osteogenesis Imperfecta (OI) is a connective tissue disorder, which is the most common cause of genetic osteoporosis characterized by long bone deformities and fractures. The key defect is the qualitative and quantitative lack of type I collagen. The primary target in these patients is to fix deformities and to prevent fractures. The surgical application is often a basic surgical technique known as "Shish Kebab" osteotomy and mainly based on the principle of multiple osteotomies, fixation, and intramedullary nailing. In the present study, we present our results of the modified Sofield procedure for osteogenesis imperfecta-related lower extremity deformities.
