- Abstract:
- Objectives To evaluate the indications of pelvic fixation in neuromuscular scoliosis patients. Methods We have measured the change in pelvic obliquity over a period of 25 months among three groups; group I with initial pelvic obliquity > 15° and pelvic fixation, group Ⅱwith initial pelvic obliquity > 15° and without pelvic fixation and group III with initial pelvic obliquity < 15° and without pelvic fixation. All patients underwent for correction and fusion for neuromuscular scoliosis using posterior-only pedicle screw instrumentations. We have used iliac screws for pelvic fixation in selected patient group. Results Comparing the Cobb's angle correction among all three groups there is significant correction post operatively and at final follow-up. There is no significant loss of correction among all three groups. However, when pelvic obliquity was compared in all three groups displayed significant correction post operatively,but group II exhibited significant loss of correction at final follow-up when compared with group I and group III. Conclusions Patients who have pelvic obliquity less than 15° do not need pelvic fixation and they can maintain the correction during a long period; while patients who have pelvic obliquity more than 15° require pelvic fixation to maintain the correction and balance over a long time.
