Leg Length Discrepancy

Also known as LLD, can be anatomical or apparent.

Anatomical LLD is where the actual leg length difference is in the measurement of the bone itself. Either the femur or tibia is shortened due to various factors such as congenital, trauma or previous accidents, surgery and underlying neurological and bone disease.

Apparent LLD is the shortening due to uneven hip stability that is caused by muscle contracture around the hip joint. This leads to one hip being higher than the other giving an impression that one leg is longer.

Associated symptoms may include:
Lower back pain
– Limping if the LLD is greater than 2cm
– Hip arthritis due to uneven body weight distribution
– Spinal curvature or tilting of the spine (scolisios)
– Difficulty in walking or running
