What is it?

Unequal leg length, or leg length discrepancy, refers to a condition in which one leg is longer than the other. Many people have unequal leg length but when the difference is big, the person may experience problems with gait, posture and pain. Functional leg length discrepancy means that the bones are equal in length but one appears longer than the other. Causes may include chronic pain, arthritis, spine, hip or knee problems, neuromuscular condition and exercise. Structural leg length discrepancy means that either the femur or the shin bone is longer than the other. Causes may include bone injuries, growth plate injuries, bone diseases, bone tumors and juvenile arthritis.
