ABSTRACT

Introduction: Tibia vara is a complex disease consisting in several deformities in the knee and leg. The treatment is controversial. Correction is achieved with current surgical techniques, but the tendency to relapse is high.
Objective: To evaluate the use of medial opening wedge proximal tibial osteotomy with fibular graft in Blount's disease.
Methods: An intervention study was achieved in 11 patients (18 lower limbs) with tibia vara. The ages of these patients ranged from 3 to 18 years, and they were assisted in the outpatient clinic of the Lower Limbs and Arthroscopy Service at Frank País International Orthopedic Scientific Complex from June 1, 2009 to May 31, 2011. These patients underwent medial opening wedge proximal tibial osteotomy. A fibular structural graft was used to correct the deformity. The clinical and radiographic criteria of Schoenecker PL and others were used for the evaluation of the surgical procedure.
Results: As of the proposal of Schoenecker PL and others, it was found that 77.77 % of the results were good; 16.66 % acceptable, and 11.11 % poor, which shows this technique was effective for the treatment. It was also determined that a tibiofemoral angle larger than 30º and an advanced radiographic stage of the disease are factors that negatively affect the results.
Conclusion: The medial opening wedge proximal tibial osteotomy with structural graft offered good clinical and radiographic results in the treatment of Blount's disease.
