The objective is to collect data from a per-operative navigation system called SURGIVISIO during scoliosis surgeries. A research program is in progress in order super-impose pre-operative 3D reconstructions of the spine performed with the EOS system on the per-operative 3D reconstructions performed with the SURGIVISIO system. The purpose of the study is to collect the pre and per operatives data in order to perform the research and development program.
Study Type

Each patient will undergo a spine fusion for a evolutive idiopathic scoliosis with the help of the surgivisio system.

RECRUITINGComparison between the shape of of the spine in supine position in the OR with the Surgivisio system and the 3D shape with the 3D pre-operative planning with the EOS
Comparison in degrees of the pre-operative Cobb angle with the EOS system and the per-operative spine reconstruction with the Surgivisio System.
