Many patients with limb length differences require no treatment. Often the difference in length is so slight it does not cause pain or difficulty in functioning. When a limb length difference is greater than one inch, surgery may be required. When a limb is to be lengthened, a lengthening device is placed on the affected limb to allow for growth in the limb and serve as a support while the developing bone strengthens.

The procedure can be performed both in children and adults with limb length discrepancy and deformity. In children limb shortening gives rise to limping, secondary scoliosis, increased energy expenditure and psychological problems. When the condition is not treated it continues to adulthood arthritis of the opposite knee and hip, and chronic back pain can develop.
