The Sagittal Plane Shear Index (SPSI) for Planning Whether to Fuse After Decompressing a Stenotic Lumbar Level

Medical Metrics Diagnostics, Inc·interventional·Posted Nov 27, 2018·Updated May 29, 2025

In Brief

A clinical study evaluating Sagittal plane shear index (SPSI) for Lumbar Spinal Stenosis and Spondylolisthesis. Completed, enrolled 100 participants across 3 sites.

Detailed Summary

The objective of the clinical investigation is to assess the proportion of lumbar spinal stenosis surgical treatment plans that change when an objective measurement of spinal stability is included and applied following a simple treatment algorithm. The objective spinal stability metric is calculated from flexion-extension radiographs using previously validated methods.
