Leg Length Discrepancy
Also known as: LLD.
What is leg length discrepancy?
Most people have a slight difference in the length of their legs, but when the difference in leg length is significant it can cause problems with mobility and development. This is when it’s a medical condition known as leg length discrepancy, or LLD.
What causes leg length discrepancy?
Leg length discrepancy can occur without an identifiable cause, but in many cases it is the result of another condition, such as a prior fracture, infection, genetics, or other orthopedic condition.
What are the symptoms of leg length discrepancy?
Many children with leg length discrepancy have no symptoms at all, but some may have trouble walking, develop pain, or have an asymmetric appearance.
What are leg length discrepancy care options?
Minor problems related to leg length discrepancy may be treated by placing a lift in the shoe of the affected leg, and observing to make sure the problems don’t grow worse. Surgery is also a common treatment for leg length discrepancy.

Limb deformities can refer to any abnormalities related to the growth and development of the arms or legs.
For children who develop certain problems with their limbs, such as bowlegs, knock-knees and others, treatment can often be difficult and invasive. Guided growth surgery is a less invasive procedure that uses plates and screws to correct the problems gradually over time with hardware that guides the growth of the limbs, but is still flexible to allow things to move and change gradually with time.
One method for treating a severe leg length discrepancy is known as epiphysiodesis. This surgical procedure involves halting the growth of the longer leg in order to allow the shorter leg to “catch up” over time.
