Detailed Description
The adolescent idiopathic scoliosis can affect the 0,5-2% of the European population. One of the widely accepted treatment of severe scoliosis (Cobb angle is over 40-50°, or more than 10° progression observed a year) is posterior correction segmentdesis with screw and rod instrumentation. As a scoliosis treatment center, about 90-110 scoliosis correction surgeries are performed in our department, using conventional preoperative planning, coronal and sagittal translation technique from posterolateral approach.
An EOS 2D/3D system is available in our department making possible the scanning of the patient with upright biplanar ultra-low dose x-rays technique. The SterEOS software makes us possible to reconstruct the surface of the spine, pelvis and lower limb. The biplanar modality of the images makes possible to 3D reconstruct any simple shape using CAD (computer-aided design) softwares.
The recent updates in the 3D scanning technology also made us possible to perform intraoperative scannings without harming the sterility.
The aim of the study to define the change of the fixation-rod's shape after scoliosis correction surgery.
Main hypothesis: there is significant change in the rod shape after implantation
Secondary hypothesis 1: during the implant of the rod, it will loose from the prebent correction depending of the severity and rigidity of the curve.
Secondary hypothesis 2: in the early stage of the rehabilitation, after the mobilization the shape of the rod (and the spinal parameters) can change Secondary hypothesis 3: after the 3. month postoperatively the shape of rod does not change anymore
