- Discussion:
- adolescent tibia vara (Blount's disease), results from disordered growth of
proximal medial physis & metaphysis;
- localized varus deformity, often accompanied by medial tibial torsion;
- caused by osteochondrosis resulting from mechanical stress converting physiologic bowlegs to tibia vara;
- risk factors: common in blacks & obese children;
- adolescent Blount's is less severe and predominately unilateral;
- Treatment:
-
high tibial osteotomy:
- also consider need for valgus femoral osteotomy;
