Preoperative Computed Tomography-Based Prediction of Device Size for Lumbar Stabilization with Interspinous Process Device for Lumbar Spinal Canal Stenosis

Key Points

This research aims to establish a correlation between preoperative CT measurements and the size of the interspinous process device used in lumbar stabilization.
Retrospective evaluation of patient records
Measurement of lumbar spinal parameters using computed tomography
Analysis of device size inserted during surgery
Significant correlation found between CT measurements and device size
Optimal preoperative CT cutoffs identified for selecting device size
Potential for improved surgical precision and outcomes

Abstract

Introduction: Lumbar stabilization using an interspinous process device is a surgical option for lumbar spinal canal stenosis. This study retrospectively evaluated the relationship between preoperative computed tomography (CT) measurements and inserted device size.
