- in adults, a two-stage anterior and posterior procedure is performed;

- arthrodesis to pelvis is often needed to correct severe pelvic obliquity and dysraphism;
- in pts w/ high-level myelomeningocele, it is important to fuse to sacrum if the curve is major and cannot be corrected below 15 deg;
- in child w/ low lumbar myelomeningocele who is able to walk, a fusion to sacrum will impair walking ability & confine child to wheelchair;
