“Changes in Lumbar Motion and Patient Outcomes After Single-Level Fusion: A Specific Patient Cluster Analysis”

https://pubmed.ncbi.nlm.nih.gov/38116633

This study found that after single-level lumbar interbody fusion, patients lose an average of 14% of their overall lumbar motion, with increases in motion at the cranial segment, but specific clusters of patients experience different changes in range of motion and patient-reported outcome measures.
