What this trial studies

This study evaluates the effectiveness of a robotic-assisted surgery technique for thoracic and lumbar spine arthrodesis compared to traditional surgical methods. It focuses on the precision of screw placement, the occurrence of complications, and the overall clinical outcomes associated with each approach. By utilizing the Mazor X Stealth™ robot, the study aims to enhance surgical accuracy and reduce risks associated with spinal surgery. Participants will be randomly assigned to either the robotic or conventional surgery group to assess the differences in outcomes.

Who should consider this trial

Good fit: Ideal candidates include adults over 18 years old who require thoracic or lumbar spine arthrodesis due to various spinal conditions.

Not a fit: Patients with a BMI of 40 kg/m² or higher, those with a history of instrumented lumbar surgery, or those with psychological disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved surgical outcomes and reduced complications for patients undergoing spine fusion.

How similar studies have performed: Other studies have shown promising results with robotic-assisted surgeries in various fields, suggesting potential success for this approach in spinal surgery as well.
