Congenital pseudarthrosis of the tibia (CPT) remains one of the most difficult conditions faced by pediatric orthopaedic surgeons. Characterized by persistent non-union, progressive deformity, limb-length discrepancy, and a high risk of refracture, CPT often requires multiple interventions throughout childhood. Achieving union is only part of the challenge—the ultimate goal is restoring function while minimizing long-term complications.

In our study published in the Journal of Orthopaedics and Traumatology, we evaluated the outcomes of the Ilizarov technique in 16 patients with CPT treated over a 13-year period. Many patients presented with particularly complex disease, including prior unsuccessful surgeries and associated neurofibromatosis. By combining the Ilizarov method with intramedullary rodding and bone grafting when indicated, we sought not only to achieve union but also to address associated deformity, limb shortening, joint contractures, and instability.

The results demonstrated a high rate of successful union, with healing achieved in 15 of 16 patients. Functional outcomes improved substantially, reflected by significant gains in AOFAS scores and encouraging clinical and radiographic results at long-term follow-up. Importantly, the Ilizarov technique allowed simultaneous correction of multiple problems commonly associated with CPT, highlighting its versatility in managing these highly complex cases.

What stands out from this experience is that successful treatment of CPT requires more than simply obtaining bone healing. Long-term surveillance, protection against refracture, and management of residual deformities remain critical components of care. The findings reinforce the value of a comprehensive reconstructive strategy that addresses both biological and mechanical factors contributing to this challenging condition.

As advances in pediatric limb reconstruction continue, studies such as this contribute valuable evidence supporting the role of circular external fixation and multidisciplinary management in improving outcomes for children with congenital pseudarthrosis of the tibia.
