“…The increased stress may stretch the disc and ligaments, allowing slippage to occur [4]. With time, the repeated grinding action of flexion and extension causes facets to become ribbon-like [13,14]. However, some [4] think that thinning of the facets and narrowing of the joint space may be the primary cause of degenerative cervical spondylolisthesis rather than the disc involvement.…”

Purpose Degenerative cervical spondylolisthesis has received insufficient attention, in contrast to degenerative lumbar spondylolisthesis. In fact, degenerative cervical spondylolisthesis may be more common than previously thought. Methods In order to provide appropriate guidelines for the treatment of degenerative cervical spondylolisthesis, a systematic review of degenerative cervical spondylolisthesis was performed. An English literature search from January 1947 to November 2010 was completed with reference to radiological examination and management of degenerative cervical spondylolisthesis. Results Of 102 patients with degenerative cervical spondylolisthesis, 52 patients (51%) had neck or occipital pain, 23 patients (22.5%) were referred with radiculopathy and 65 patients (63.7%) presented with myelopathy or myeloradiculopathy. Degenerative cervical spondylolisthesis was most common in C3/4 and C4/5, occurring in 81 patients at C3/4 (46%) and 87 at C4/5 (49.4%). Disc degeneration and facet hypertrophy were the main causes of this clinical entity. Of 123 patients, 57 (46.3%) were found to have segmental instability as shown by flexion-extension lateral radiographs. There are two classification systems for degenerative cervical spondylolisthesis. Surgery was indicated in patients who had radiologically proven cervical spondylolisthesis with instability and/or spinal cord compression. Conclusion Prospective studies should be designed in the future to draw a more reliable conclusion about the management of degenerative cervical spondylolisthesis.

“…9,10,16 Olisthy, limited to one-quarter of the vertebral body, is generally attributed to a locking of sagitally-oriented, hypertrophied posterior facet joints. 16 Disc herniations accompany degenerative spondylolisthesis in 4.3 ± 20% of patients. Far lateral disc herniations occurring at the level of a slip typically require full unilateral facetectomy with an instrumented fusion to avoid instability in patients under 65 years of age, while select patients over the age of 65, may alternatively be addressed with a more restricted in situ posterolateral intertransverse fusion.…”

Far lateral disc herniations constitute 7 ± 12% of all disc herniations. They may be purely far lateral or extraforaminal in location, located beyond the pedicles, or may include intraforaminal and even intracanalicular components. Occurring predominantly at the L4 ± L5 and L3 ± L4 levels in almost equal numbers, they are occasionally noted at L5 ± S1. Clinical syndromes re¯ect compression of the superiorly exiting nerve root and ganglion; ie an L4 ± L5 far lateral disc produces a L4 root syndrome. Clinical complaints often include severe radicular pain accompanied by very positive mechanical signs; LaseÂ gue and reverse LaseÂ gue (femoral stretch test) maneuvers. Neurological de®cits, including motor, re¯ex, and sensory ®ndings, are seen over 75% of the time. Although conservative management is occasionally successful (10%), surgery is usually required. The extent of stenosis and attendant degenerative changes dictate whether laminectomy, hemilaminectomy or laminotomy are required along with one of several facet resection options; full facetectomy, the intertransverse approach, medial facetectomy, or an extreme lateral procedure. Postoperatively, patients' neurological outcomes based on both surgeon and patient based outcome measures (SF-36), were comparable for the dierent surgical procedures which had been based on the individual patient's pathology.
