Infantile Blount's disease is a condition that causes genu varum and internal 
tibial torsion. Treatment options include observation, orthotics, corrective 
osteotomy, elevation of the medial tibial plateau, resection of a physeal bar, 
lateral hemi-epiphysiodesis, and guided growth of the proximal tibial physis. 
Each of these treatment options has its disadvantages. Treating the coronal 
deformity alone (genu varum) will result in persistence of the internal tibial 
torsion (the axial deformity). In this report, we describe the combination of 
lateral growth modulation and distal tibial external rotation osteotomy to 
correct all the elements of the disease. This has not been described before for 
treatment of Blount's disease. Both coronal and axial deformities were corrected 
in this patient. We propose this combination (rather than the lateral growth 
modulation alone) as the method of treatment for early stages of Blount's 
disease as it corrects both elements of the disease and in the same time avoids 
the complications of proximal tibial osteotomy.
