Treatment Concepts of Osteogenesis Imperfecta

Background: To explore the Application of the intramedullary nails for correction of deformity in the lower limbs and decrease the opportunity of refractures in children with osteogenesis imperfecta.Materials and Methods: From July 2005 to July 2009, 11 patients (5 males and 6 females), were recruited from Emergency and outpatient department having deformities of osteogenesis imperfecta in lower limbs. With 3 femurs and 5 tibias with deformity in lower limps were corrected by multiosteotomy and fixed with intramedullary interlocking nails, 6 (3 femurs and 3 tibias) for Rush nails; 6 (2 femurs and 4 tibias) for Ender nails; and 12 (6 femurs and 6 tibias) for flexible intramedullary nails. All patients were operated under general or spinal anesthesia. Results: All deformities were perfectly corrected. All patients were available at final follow up, for 9 months to 36 months, mean 18 months. 2 patients had delayed union, 2 had superficial infection in the incision or pin tract, and 1 had refractures postoperatively. The results were excellent in 72.727% and good in 27.272% patients. Conclusion: Multiosteotomy and fixed intramedullary nails can correct the deformity in the lower limbs perfectly and decrease the opportunity of refractures in children with osteogenesis imperfecta, which has been proved to be a reliable method.
