Morphological asymmetry of the superior Cervical facets from C3 through C7 due
to Degeneration

Vrije Universiteit Brussel, Belgium
Introduction:
Knowledge about facet morphology has
already been discussed extensively in literature but is limited
regarding asymmetry and its relation to facet degeneration.
Method:
Facet dimensions, surface area, curvature, and
degeneration of the superior facets were measured in 85
dried human vertebrae from the anatomical collection of
the Vrije Universiteit Brussel. The vertebrae were analysed
using the Microscribe G2X digitizer (Immersion Co., San Jose,
CA) and a grading system for the evaluation of cervical facet
degeneration. Coordinates were processed mathematically
to evaluate articular tropism. The statistical analysis includes
the paired t-test and the Pearson correlation.
Results:
On average, no systematic differences between the
left and right facets were found concerning morphology and
degeneration. However, there were significant differences
regardless of the side-occurrence. There was a significant
correlation between the dimensions of the total facet surface
and the degree of degeneration but not for the recognizable
joint surface.
Conclusions:
Facet tropism of the upper joint facets occurred
often in the cervical spine but without side preference. A
bigger difference in degeneration asymmetry was associated
with a bigger difference in facet joint dimension asymmetry.
