This procedure corrects a leg length difference. With surgery and devices, a bone can be lengthened over a period of time. The process triggers bone growth and soft tissue lengthening.
Lengthening may be needed if you have a length difference due to:
- Trauma, such as a leg fracture
- Bone infection
- Congenital defect or other condition that affects your bone growth, such as Klippel-Trenaunay syndrome
- Short stature, such as dwarfism
- Cerebral palsy
If the difference is not corrected, it can cause excess strain on joints. You could have pain in your knee, hip, or ankle. You may develop osteoarthritis and back pain.
Correcting the problem can help improve walking and reduce your risk of other problems. Depending on the technique, several inches may be added.
