Can a computer predict your posture after back surgery?
NCT ID NCT04422288
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a computer model can accurately predict a patient's posture after spinal fusion surgery. Researchers used data from 200 adults who had thoracolumbar spinal fusion and compared the model's predictions to their actual posture at follow-up. The goal is to help surgeons plan operations that lead to better balance and comfort.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this model could help surgeons plan spinal fusion surgeries more accurately, potentially reducing complications like poor posture or imbalance.
- What could go wrong
- This is a validation study, not a treatment trial. The model may not accurately predict posture for all patients, and it does not test any new surgical technique or device.
