Anterior Surgery in Multilevel Stenosis of the Lower Cervical Spine: Technical Indications and Personal Experience. 12 Years Follow-Up


Objective: cervical spondylotic myelopathy is a progressive degenerative cervical spine disease. During later stages of segmental degeneration, kyphosis of the cervical spine can occur and further compromise the spinal cord and nerve roots. Optimal surgical approach remains controversial. The choice to perform an anterior, posterior or combined approach depends on: sagittal alignment, number of involved levels, main compression localization, and clinical status. The anterior approach is recommended when compression involves primarily anterior horn of spinal cord. Methods: between January 2001 and December 2005, 121 patients (42 F, 79 M, mean age 62 years) were operated for cervical spondylosis (98 myelopathy, 23 radiculopathy). Anterior surgical approach was performed in 81 patients. 63 patients were operated performing multilevel discectomy and fusion (ACDF) and 18 patients performing corpectomy and fusion and anterior plating (ACCF). Preoperative documentation collected consisted of cervical X-ray (static-dynamic), cervical spine TC, cervical MRI. Clinical documentation permitted us to obtained clinical status of each patient based on JOA, NDI and VAS. A Clinical and radiological follow-up was performed at 1 month, 3 months, 1 year, 6 years, 12 years. Results: the fusion rate was calculated based on the static and dynamic X-ray (flexion and extension position), only a little percentage of patients underwent CT scan. There were no significant differences between ACDF and ACCF in clinical outcome at 6 years evaluated by VAS and NDI. The rate of fusion at 6 years for 2 levels ACCF (92%) was higher than that for 2 levels ACDF (86%) but is not statistically significative. Conclusion: classifying degenerative disease and biomechanics feature, preoperatively in necessary to guide the surgeon to choose the best anterior approach for cervical spondylosis.
