What Are the Causes of Leg Length Discrepancies?
LLDs are very common. Sometimes the cause isn’t known. But the known causes of LLD in children include: • Injury or infection that slows growth of one leg bone. • Injury to the growth plate (a soft part of a long bone that allows the bone to grow). Growth plate injury can slow bone growth in that leg. • Fracture to a leg bone that causes overgrowth of the bone as it heals. • A congenital (present at birth) problem (one whole side of the child’s body may be larger than the other side). • Conditions that affect muscles and nerves, such as polio.
