Combined bone plasty interventions for rehabilitation of patients with congenital pseudarthrosis of the tibia

The problem of treating patients diagnosed with congenital pseudarthrosis is due to severe and unpredictable course of this disease, difficulties in choosing surgical techniques, and frequent relapses of the process. Purpose Compare the results of treatment of patients with congenital pseudoarthrosis of the tibia (CPT) using non-free Ilizarov bone plasty and a combination of grafting according to Masquelet technique with Ilizarov bone transport. Materials and methods The outcomes of 13 patients with CPT aged 1.5 to 35 years who had been treated since 2009 were analyzed. The main group (n = 6) included patients treated using a combination of the Ilizarov and Masquelet methods. In the control group (n = 7), patients were treated only with Ilizarov transosseous osteosynthesis. Histological examination of the periosteum and tissues of the resected pseudarthrosis area was performed. In the index group, fragments of a biomembrane formed around a cement spacer temporarily bridged the diastasis after resection of pseudarthrosis were studied by light and electron scanning microscopy...
