Discovered this topic four years ago. After conducting research, realized the risk was considerable (not zero) and lacked financial means. Ceased all consideration of limb lengthening. Skipping ahead to this year, exhausted other alternatives and had to make a change in life. Financial situation improved, and delved deeper into the subject, such as on this forum. Developed a sense of having a 95% likelihood of success. Once decision was made, surgery was scheduled within three weeks.
