Abstract: Objective    To investigate the relationship between sagittal angle asymmetry of cervical facet joint and the degeneration of cervical facet joint.    Methods   The sagittal facet angle and the degeneration degree of 160 facet joint at C3/4-C6/7 segments on the axial CT of 20 fresh cervical cadaver specimens were evaluated blindly and statistically analyzed by 3 reviewers using the 4-degree evaluation method.    Results   There was no significant difference in sagittal asymmetrical angles of the facet joint between different segments (F= 0.55,P=0.65), and  there was also no significant difference in the degeneration of cervical facet joint (left: Z=3, P=0.646; right: Z=3, P=0.376) between different segments, but there were significant differences between the sagittal angle asymmetry of cervical facet joint and the degeneration of cervical facet joint  at C3/4 and C4/5 segments of 20 fresh cervical cadaver specimens(C3/4:Z=8.567, P=0.014,C4/5; Z=2.000, P=0.025).   Conclusion    The sagittal angle asymmetry of cervical facet joint may be related to the degeneration of the facet joint.
