Degenerative spondylolisthesis of the cervical spine: analysis of 58 patients treated with anterior cervical decompression and fusion

摘要: Abstract Background context Degenerative spondylolisthesis has been well described as a disorder of the lumbar spine. Few authors have suggested that similar occurs in cervical To our knowledge, present study represents largest series patients with long-term follow-up who were managed surgically for treatment degenerative Purpose describe clinical presentation and radiographic findings associated spondylolisthesis, to report results patients. Study design Analysis 58 treated anterior decompression fusion Patient sample From 1974 2003, identified having spine occurring absence trauma, systemic inflammatory arthropathy, or congenital abnormality. These from database approximately 500 disorders by senior one us. Outcome measures outcomes evaluated regard neurologic improvement (Nurick grade myelopathy) osseous fusion. Methods The records reviewed. average period was 6.9 years (range, 2–24 years). Seventy-two levels demonstrated spondylolisthesis. In all cases, there evidence facet degeneration subluxation. All arthrodesis iliac crest structural graft. This most commonly involved corpectomy caudal vertebrae. Three required additional posterior Results Fifty-eight 72 involvement. C4–C5 level frequently (43%). Two radiographically distinct types listhesis observed based on amount disc degree spondylosis at adjacent levels. 1.5 Nurick grades. overall rate 92%. combined anterior-posterior arthrodesis. prevalence myelopathy instability pattern greater listheses spondylotic Conclusions is relatively common Common cases arthropathy compression. Anterior appears yield excellent union rates neurological those significant sequelae failed nonoperative treatments.
