The purpose of this study is to determine the effect of double end spinal instrumentation from the upper thoracic to the pelvis with sacro-iliac fixation on the gait of ambulating patients with pelvic obliquity 6 month after surgery.


The pelvic fixations were used since many years for these patients. However there are no prospective study investigating the gait evolution before and after a surgical treatment by long spinal instrumentation with pelvic fixation.

Investigators are planning to analyze the gait, before and 6 months after surgery. Investigators will use 2 qualitative criterions with a gait analysis and a walking test, and 1 quantitative criterion with a questionnaire assessing the patient's functional change. Investigators will use as surgical treatment a long double end spinal fixation without fusion, investigators use an ilio sacral screw as pelvic anchor on each side.

Evaluation of changes in gait after pelvic fixation of a long spinal instrumentation will make it possible to extend or, on the contrary, restrict the indications for pelvic fixation surgery in walking patients, who are candidates for pelvic fixation.
