Study of Walk in Patients With Pelvic Fixation

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in the score of CPCHILD (section 2) questionnaire from 6 months before spinal surgery at 6 month after spinal surgery | to assess the quality criteria of walk | 6 months before and 6 months after spinal surgery | 
| Change in Clinical Gait Analysis from 6 months before spinal surgery at 6 month after spinal surgery | to assess the quantitative criteria of walk | 6 months before and 6 months after spinal surgery | 
| Change in 6-minute walking test from 6 months before spinal surgery at 6 month after spinal surgery | to assess the quantitative criteria of walk | 6 months before and 6 months after spinal surgery | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| presence / absence of cardiac impairment | cardiac evaluation to evaluate assess if cardiac impairment before spinal surgery is a the good or bad prognosis for walking | 6 months before spinal surgery | 
| presence / absence of respiratory impairment | pulmonary evaluation to assess if respiratory impairment before spinal surgery is a good or bad prognosis for walking | 6 months before spinal surgery | 
| presence / absence of neurological impairment | neurological evaluation to assess if neurology impairment before spinal surgery is a good or bad prognosis for walking | 6 months before spinal surgery | 
| Change in reducibility of scoliosis from 6 months before spinal surgery at 6 month after spinal surgery | to evaluate the good or bad prognosis for walking | 6 months before and 6 months after spinal surgery | 
| Change in holding of the head  of scoliosis : from 6 months before spinal surgery at 6 month after spinal surgery | to evaluate the good or bad prognosis for walking | 6 months before and 6 months after spinal surgery | 
| Change in curvature of scoliosis from 6 months before spinal surgery at 6 month after spinal surgery | to evaluate the good or bad prognosis for walking | 6 months before and 6 months after spinal surgery | 
| Change in imbalance of scoliosis from 6 months before spinal surgery at 6 month after spinal surgery | to evaluate the good or bad prognosis for walking | 6 months before and 6 months after spinal surgery |
