INTRODUCTION. Since onset of XX century, with appearance of new surgical techniques for fractures treatment, the number of complications increased including the infections and the pseudoarthrosis. Despite the scientific advance of Orthopedics in past 20 years, the pseusoarthoris remains to be a frequent complication in patients undergone very complex lesions and most of time it is caused by a wrong application of biomechanical principles of Ilizarov in treatment of long bones pseusoarthrosis. METHODS. A prospective and longitudinal study was conducted to analyze the case of 11 patients with long bone pseudoarhtosis as sequelae of fracture treatments (4 of them infected). Treatment included external fixation using the Gabriel Ilizarov's external fixation (circular model) and the external fixation type RALCA® designed by the professor Rodrigo Alvarez Cambras (biplane model). Ten pseudoarthrosis of tibia and one of femur were treated. RESULTS. As average consolidation was achieved at 5 months in simple pseudoarthrosis and at 8 months in those infected. The more frequent complications were the osteitis in the wire trajectory and the partial articular rigidities caused by previous treatments. CONCLUSIONS. Given the good results obtained, it was considered useful to show our results based on the IIizarov'v principles as another procedure to solve this type of affection.
