Abstract
Osteogenesis imperfecta (OI) is a heterogeneous group of diseases with different types of inheritance, characterized by frequent fractures and deformities of the bone skeleton. Conservative and surgical treatment of children with this pathology is an integral part of a multidisciplinary approach. In the surgical treatment of bone deformities in children with OI, the method of choice is corrective osteotomies, and an effective method of fixation is intramedullary osteosynthesis. Surgical treatment of children with OI is aimed at reducing the number of fractures, correcting deformities and increasing motor activity. Aim of the study to determine the indications for intramedullary osteosynthesis of long tubular bones in children with the disease. To review the studies concerning treatment of children with OI. Consider the different types of metal fixers, their advantages and disadvantages. Today the technique of intramedullary fixation is the "gold" standard in the surgical treatment of children with OI. There is a clear advantage of telescopic rods in terms of the frequency of reoperations, but their use does not exclude the presence of postoperative complications.
