Fourteen multilevel osteotomies with Rush pin fixation have been performed in 5 children with osteogenesis imperfecta. The age of patients at the operation ranged from 6.5 to 15.5 years. Plaster of Paris immobilization never exceeded 8 weeks. An axial correction, improved ambulating and equalization of the limbs have been achieved in all cases. Complications of the method included varus deformity of the proximal tibia (1 case), migration of the pin (1 case) and supracondylar fracture of the femur at the level of pin end (2 cases).
