Comparing 3D-Printed Model and CT Scan Planning for Spine Stabilization Surgery in Thoracic and Lumbar Spine Trauma

What this Trial Is About

Researchers are evaluating two methods of planning spine stabilization surgeries for patients with traumatic injuries to the lower thoracic or lumbar spine. The study compares conventional preoperative planning using CT scans with planning based on patient-specific 3D-printed spine models. This trial intends to assess how these approaches affect surgical outcomes such as blood loss during surgery. Participants undergo standard bisegmental posterior spine stabilization surgery through a midline approach. One group receives surgery planned with conventional CT scans and fluoroscopy guidance, while the other group has surgery planned with the aid of 3D-printed spine models along with the same fluoroscopy guidance. Both groups undergo the same surgical technique with different preoperative planning tools. During the study, researchers will monitor surgery-related factors including blood loss during the operation, surgical duration, accuracy of pedicle screw placement, and the length of the surgical incision. Assessments occur during surgery and postoperatively, with screw placement accuracy evaluated on the first day after surgery and incision length checked around the time of suture removal approximately 10 to 14 days post-surgery. The study is randomized and single-blinded, involving follow-up to measure these outcomes.
