Objective: This retrospective study evaluated treatment with individually contoured molded bracing at early stages of the disease. Methods: We evaluated the medical records of patients undergoing treatment of Blount's disease with molded orthoses for medial decompression between 2010 and 2014. The deformity angle (Drennan's metaphyseal-diaphyseal angle) and Langenskiöld classification were measured before and after treatment by a pediatric orthopedic surgeon with over 5 years of practice, blinded for the study and patients. Results: The mean age was 2.57 years old. Four patients were female and six male. Half of the total sample had bilateral disease. The average deformity angle showed a statistically significant reduction after treatment (p <0.001). Gender and laterality did not statistically influence the change of the deformity angle after treatment (p> 0.05). Conclusion: The nightly use of molded orthoses for medial decompression was effective in reducing the metaphyseal-diaphyseal angle in Blount's disease in children under 3 years of age, regardless of gender and bilateral disease. Patients over 3 years old did not benefit from bracing. Level of Evidence IV, Case Series.
