“…Traumatic spondylolisthesis of the axis is a failure in the pars interarticularis of the neural arch and a separation from the C2 vertebral body [4]. On the other hand, the main cause of degenerative cervical spondylolisthesis is arthrosis of the facet joints, disc degeneration, and cervical sagittal malalignment [5]. Cervical spondylolisthesis is not a rare condition in the elderly.…”

This study aimed at presenting a rare nontraumatic spondylolisthesis of the axis and considering its possible cause. Traumatic spondylolisthesis of the axis, called hangman's fracture, frequently occurs as a high-energy trauma. However, nontraumatic spondylolisthesis of the axis is quite rare, and relevant literature on this condition is scarce. We reported a case of a 49-year-old man who had spondylolisthesis of the axis without experiencing a traumatic episode. Plain radiograph and CT image showed 7.0 mm anterolisthesis of the axis. Both C2 and C3 facet joints positioned asymmetrically, and the unilateral side oriented coronally, which was less resistant to rotational motion. These facet joint abnormalities could cause segmental instability and spondylolisthesis of the axis. Due to the resultant myelopathy, the slip with cord compression was surgically corrected by posterior decompression with instrumented fusion.

“…However, degenerative cervical spondylolisthesis may be more common than previously thought [3]. The main causes of degenerative cervical spondylolisthesis are arthrosis of the facet joints, disc degeneration and cervical sagittal mal-alignment [4]. Increased stress with flexion and extension may damage the disc and ligaments, allowing slippage to occur [5,6].…”

Degenerative spondylolisthesis of the cervical spine is relative rare. We present a relative rare case of severe degenerative cervical spondylolisthesis with posterior corrective fusion. A 70-year-old female complained of neck pain and gait disturbance with cervical spondylotic myelopathy. Plain radiographs showed 8.3 mm anterolisthesis of C3/ C4, which gradually progressed during four years. The slip was not reduced by flexion and extension position. After releasing C3/C4 facet joint and yellow ligament, posterior reduction with instrumentation were performed and resulted in successful cervical correction and fusion.

“…A plain computed tomography (CT) or myelogram-CT image was taken of each patient. We defined cervical spondylolisthesis as anteroposterior vertebral slipping of more than 2 mm, identified on lateral standing X-ray images in a neutral position or on sagittal CT images according to the criteria describes in previous papers 3,[6][7][8] . Motion of 1 mm or greater on flexionextension views was considered to represent instability, according to a previous paper 5) .…”

Abstract:Introduction: The characteristics of cervical spondylolisthesis are not currently fully understood, because of the shortage of reports covering the large population of patients with cervical spondylolisthesis. The purpose of this study was to elucidate the characteristics of cervical spondylolisthesis by examining a relatively large number of cases.Methods: We analyzed 101 cases with more than 2 mm of vertebral listhesis as determined from X-ray or computed tomography (CT) images among 731 patients who underwent surgery at a single institute. We considered the C2-7 angle, range of motion, and C2-7 sagittal vertical axis on lateral X-ray images. From sagittal CT images, classifications into five grades based on the slipped disc and adjacent caudal levels were made. We examined the orientation of facet joints at the slipped level using axial CT images.Results: Spondylolisthesis was recognized in 101 cases at 124 levels. Anterior and posterior spondylolisthesis were detected in 68 and 40 cases, respectively. Anterior spondylolisthesis developed predominantly at C3 or C4, usually at the level adjacent to the narrowed disc, or at C7, adjacent to the stiffened thoracic spine. The disc height was relatively preserved at the anterior slipped level. Posterior spondylolisthesis developed predominantly at the level of the significantly narrowed disc associated with advanced intervertebral osteoarthritis. At the segment with listhesis in the lower cervical spine, the direction of the facet joint in the axial plane tended to be posteromedial.Conclusions: Cervical degenerative spondylolisthesis was classified into two types. The first and more common listhesis occurred adjacent to stiffened levels, and anterior slippage was common in this type. The second and less common listhesis occurred within progressively degenerated segments, and posterior slippage was prominent. We have uniquely described the morphological changes in orientation of the cervical facet joints at the slipped level in the transverse plane.
