Retrospective cohort study examines superior facet joint violation impact on adjacent segment degeneration in lumbar fixation.
McNamee et al.1 present a retrospective cohort study examining the relationship between superior facet joint violation (FJV) and adjacent segment degeneration (ASD) following lumbar pedicle screw fixation. The authors aimed to determine whether FJV, graded using a three-tier CT-based classification system, is independently associated with radiographic degeneration or reoperation at the cranial adjacent segment.
