Interspinous Nonpedicle Fixation Devices for Lumbar Spinal Fusion

This report addresses whether full-text clinical studies, systematic reviews, and clinical practice guidelines and position statements support the use of interspinous process fixation devices (IPFDs) compared with conventional instruments for lumbar spinal fusion (LSF) (e.g., employing pedicle screws, rods, plates) for patient-oriented outcomes, imaging outcomes, and procedure-related outcomes.
