Congenital pseudarthrosis of the tibia (CPT) is one of the most challenging problems in pediatric orthopaedics. The treatment goals are osteosynthesis, stabilization of the ankle mortise by fibular stabilization, and lower limb-length equalization. Each of these goals is difficult to accomplish but regardless of the surgical options, the basic biological considerations are the same: pseudarthrosis resection, biological bone bridging of the defect by stable fixation, and the correction of any angular deformity. The Ilizarov method is certainly valuable for the treatment of CPT because it can address not only pseudarthrosis but also all complex deformities associated with this condition. Leg-length discrepancy can be managed by proximal tibial lengthening using distraction osteogenesis combined with or without contralateral epiphysiodesis. However, treatment of CPT is fraught with complications due to the complex nature of the disease, and failure is common. Residual challenges, such as refracture, growth disturbance, and poor foot and ankle function with stiffness, are frequent and perplexing. Refracture is the most common and serious complication after primary healing and might result in the re-establishment of pseudarthrosis. Therefore, an effective, safe and practical treatment method that minimizes the residual challenges after healing and accomplishes the multiple goals of treatment is needed. This review describes a multi-targeted approach for tackling these challenges, which utilizes the Ilizarov technique in atrophic-type CPT.
