In younger patients with limb length discrepancies (where one side is longer than the other), complications can arise if left untreated, including hip/knee/ankle problems, or even scoliosis.
Surgery can be done to encourage new bone growth to help balance out both sides.
This often starts with a procedure called an osteotomy, where part of the bone is cut away and the bone spread apart. Hardware is inserted to stabilize the bone while new cells begin growing in that newly created gap to create new bone.
Correction procedures can be done on other similar conditions, whether congenital or caused by trauma.
