Cement Distribution and Pain Relief in Unipedicular Vertebroplasty

425 patients treated from 2021 to 2024 were analyzed for the effect of dominant cement zone on pain relief after vertebroplasty. The study by Murat Özcan Yay uses a four-zone classification of cement distribution within the vertebral body. Mean visual analog scale (VAS) pain scores decreased from 7.63 to 3.31 post-procedure.

Use Cases

• Predict change in VAS pain score using dominant cement zone, preoperative VAS, and cement volume as features in a linear regression model.
• Classify clinical response (VAS change > 4) via logistic regression using zone, preoperative VAS, and cement volume as predictors.
• Analyze complication rates, such as the 45.4% cement leakage incidence, relative to cement distribution patterns.
• Compare mean VAS change outcomes across the four defined vertebral body zones to identify optimal cement placement.

Strengths

• Analysis of 425 patient records provides a substantive clinical sample.
• Strong model performance indicated by a linear regression R² of 0.724 and a logistic regression Nagelkerke R² of 0.729.
• Clear temporal coverage from 2021 to 2024.

Limitations

• Dataset scope is limited to a 16.2 KB document, suggesting summary statistics rather than raw patient-level data.
• Retrospective study design may introduce selection bias.
• Specific patient demographics and full column details are unknown.
