Conditions

lumbar stenosis, fractures of the lumbar or thoracal segment, scoliosis

Interventions

Group 1: A total of 40 patients will be recruited and divided into two groups. Both groups will be randomized. In the control group, consisting of 20 patients, routine dorsal stabilization will be per

Design outcomes

Primary

Measure	Time frame
The aim of the study is to address the following research question: We hypothesize that the more precise, virtual reality–assisted bending of the rods leads to a reduction in screw–rod misalignment and thus proves superior in preventing screw pullout complications, as well as in improving postoperative pain. All patients will be thoroughly informed about the procedure and their participation in the study and will complete the preoperative part of the questionnaire. The questionnaire consists of the VAS (Visual Analog Scale) and the ODI (Oswestry Disability Index). On the first postoperative day, routine imaging diagnostics of the operated segments will be performed using computed tomography (CT) and X-ray, in accordance with the clinic’s standard treatment protocols. On the fifth postoperative day, patients will complete the second part of the questionnaire (VAS and ODI). Routine follow-up will be carried out in accordance with the clinic’s treatment regimen, with check-ups at the neurosurgery outpatient center after 6–8 weeks, 6 months, and after 1 year. At each appointment, the questionnaire will be completed again. The findings, as well as the data obtained from imaging (X-ray and CT), will be collected for the study. The imaging diagnostics are performed as part of routine follow-up care; therefore, no additional data collection is required.	—
