3D-printed models to plan spine screw placement in thoracic and lumbar trauma
Official title: Impact of 3D Printed Models on Preoperative Planing in Thoracic and Lumbar Spine Trauma
Run by Masarykova Nemocnice v Usti nad Labem, Krajska Zdravotni a.s. · NCT07727161 · Data updated 2026-11-12
In people with certain thoracic or lumbar spine injuries, this study tests whether using a patient-specific 3D-printed model to plan pedicle screw fixation helps compared with standard CT planning.

Is this trial a fit for you?
✓Likely a good fit
Adults with a single vertebra AO A2-A4 thoracic or lumbar fracture indicated for spine fixation, without neurological impairment.
✕Probably not a fit
Patients with complex multivertebral injuries, neurological impairment from the fracture, or those who do not require pedicle screw fixation may not benefit.

What this trial studies
This interventional case-series compares two groups of about eight patients each undergoing pedicle screw fixation for single-vertebra thoracic or lumbar injuries (AO A2-A4). The control group uses conventional preoperative CT planning with fluoroscopy-guided fixation, while the experimental group uses identical fixation but with planning based on a 3D-printed patient-specific model. The aim is to see if 3D printing can improve planning and accuracy without altering the fixation technique. Participants are adults with thoracic or lumbar spine fractures without neurological impairment. The study is conducted at Masaryk Hospital in Ústí nad Labem, led by Masarykova Nemocnice v Usti nad Labem with Krajska Zdravotni a.s. as sponsor.
Why it matters
Potential benefit: If successful, planning with 3D-printed models could improve screw placement accuracy and streamline surgical planning for spine trauma.
How similar studies have gone: Previous work in 3D printing for surgical planning in spine procedures has shown promise, but results vary and this exact approach is being evaluated in a small case-series.
