While many of you may not have heard of Blount disease, it still affects a sizeable portion of the world’s child population.

It is a developmental disorder which is characterized by a disordered growth of the proximal tibial physis. This leads to deformity of the lower limb in progressive phases. Blount’s disease may also be associated with limb length discrepancy and could even lead to the deformity of the distal femur too.

Blount Disease – Forms:

Your child may be suffering from one of the following forms of the disease:

  1. Infantile Blount disease which is usually diagnosed when a child is between the ages of 1 & 3.
  2. Late-onset Blount disease which can be characterized into two categories:
  • Juvenile (between 4-10 years)
  • Adolescent (children above 10 years)

Blounts disease which occurs in children who are older is normally associated with obesity and is more or less unilateral.

  2. Other children are asked to undergo extensive surgery.
  3. A surgery may require the surgical team to cut the tibia and then realign and hold it with a plate.
  4. Surgery may involve removing the damaged growth plates.
  5. Use of an external device to support the bone plate externally as opposed to internally.
  6. Surgery could also involve correcting the twist in the toe that is the root cause of the disease.
