Limb Length Discrepancy (LLD) and Deformities

Limb Length Discrepancy (LLD) or inequality in the lengths of the lower limb is usually a source of concern for many parents. Fortunately most times these difference are so small that they are not apparent clinically and do not warrant any intervention.

However, in a smaller group of patients there can be a significant difference in which case the source needs to be investigated and appropriate treatment instituted.

​Some of the conditions that can cause Limb Length Discrepancy are:

• Hemi hypertrophy - Idiopathic (no known cause) or secondary to increase blood flow to the limb
• Hip conditions - Like neglected dislocations
• Arrest of the growth plate secondary to infections and injury to the growing areas of the lower limbs
• Foot condition like clubfeet which causes the affected foot to be smaller leading to a shorter foot height and subsequently a shorter leg

​The treatment can range from masterly inactivity to the latest intramedullary implants. The treating doctor will decide on the course of treatment based on the cause of the Limb Length Discrepancy and its response to the various modes of treatment.
