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.

• Treatment of adolescent tibia vara by asymmetrical physeal distraction.
• Adolescent tibia vara: alternatives for operative treatment.
• Blount's disease after skeletal maturity.
• Comprehensive Treatment of Late-Onset Tibia Vara
• Outcome of Hemiepiphyseal Stapling for Late-Onset Tibia Vara.
• Results of Screw Epiphysiodesis for the Treatment of Limb Length Discrepancy and Angular Deformity.
