2024/04/17
What is Limb Length Discrepancy?

‚ÄčIt is the unequal lengths of the lower limbs. May affect entire limb or a segment of the limb.

What causes Limb Length Discrepancy?
  • Undergrowth of one limb due to malformation, previous infection or injury.
  • Overgrowth of one limb due to malformation, previous injury or an unknown cause (Idiopathic)
What are the symptoms?
  • Standing posture of the lower limbs may not be symmetrical.
  • One side of the pelvis may be higher than the other.
  • There may be a secondary curvature of the spine with tilting of the shoulders.
  • Usually a painless condition.
Treatment options
  • The underlying cause needs to be addressed.
  • The age of the child and predicted growth remaining needs to be considered.
  • If small difference in length, a shoe lift can be used for the shorter side.
  • Larger differences in length can be treated surgically by slowing the growth of the longer limb or lengthening the shorter limb.
