The purpose of this study was to investigate the initial union rate, refracture rate and residual deformities congenital pseudarthrosis tibia (CPT), using combined surgery including resection, intramedullary rodding, autogenous iliac bone grafting Ilizarov's fixator, with a mean 5.2 years follow-up. We retrospectively reviewed records diagrams patients Crawford type IV between February 2007 March 2010. Patients managed by rod tibia, wrapping fixator were enrolled. evaluated tibial alignment, limb length discrepancy (LLD), valgus deformity ankle frequencies during period There 56 cases enrolled in study, follow-up (range, 3 6.7 years). age at 3.5 1.5 12.4 Fifty (89.2 %) had primary site pseudarthrosis, while 5 obtained after second 1 failed. average time spent obtain 4.5 months 3.0 10.0 months) duration Ilizarov treatment 4.7 3.2 10.4 months).
