New outlooks in the treatment of osteogenesis imperfecta. An unusual case successfully treated by the Ilizarov method.

The authors describe a rare case of osteogenesis imperfecta in a patient aged 29 years affected with equal deformities of the lower extremities. In the right tibia a pseudarthrosis due to a fatigue fracture had occurred at the apex of the deformity. Treatment by the traditional methods posed serious problems, both technical and from the point of view of repair of the pseudarthrosis and the trophic changes. These problems were solved by using the Ilizarov compression-extension apparatus.
