Adolescent Blounts Disease



- 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;
                - Femoral deformity in tibia vara
                - Comprehensive treatment of late-onset tibia vara.
