Leg lengthening surgery can also be used to remedy the situation surgically. This procedure is the most complicated and expensive option. It stimulates the bone in a patient?s leg which is shorter than the other grows longer by surgically cutting the bone and inserting a device that gradually moves the two ends of the bone apart to enable the lengthening of the bone. Bone lengthening is a process that requires very patient monitoring and extreme care. Any accident or stress in the area can disrupt the entire process. This is because the space that opens up between these two ends is extremely vulnerable.
