Aseptic nonunion and delay in consolidation in the tibia: treatment by intramedullary nailing and using the Ilizarov...

The authors present a clinical-radiographic study on two groups of patients affected with aseptic nonunion and delays in consolidation of the tibia treated by intramedullary nailing (24 cases) and Ilizarov method (29 cases). Nailing was locked in 12 cases and associated with resection of the fibula in 15 (in 8 locked nailing). Autoplastic bone grafts were applied in 3 cases of atrophic nonunion. The Ilizarov method was used with different procedures: standard assembly in 23 patients, of which 6 with the application of autoplastic grafts for atrophic nonunion. En bloc resection of the atrophic nonunion was carried out in 6 patients followed by removal (4 cases) or lengthening (2 cases). Parafocal osteotomy according to Paltrinieri was reserved for closed hypertrophic nonunion with severe varus and procurvatum. The data for this study allow the authors to conclude that intramedullary nailing is preferable in delays in consolidation and in hypertrophic nonunion without angular defects or hypometria, while the Ilizarov method is more indicated in atrophic nonunions and in hypertrophic nonunions with hypometria and angular defects.
