Combined technique of titanium telescopic rods and external fixation in osteogenesis imperfecta patients: First 12 consecutive cases.

Introduction: The major limitation of any intramedullary telescopic system is rotational and longitudinal instability. The combination of telescopic system with an external fixator in patients with osteogenesis imperfecta (OI) demonstrated advantages of stability, early weight-bearing and rehabilitation. This study aimed to examine the outcomes of deformity correction by combined technique uniting titanium telescopic rod and reduced Ilizarov frame in children with types III or IV of OI with a minimum 1-year follow-up.
