Abstract
PURPOSE: To compare the postoperative sagittal balance and occurrence of axial symptoms between anterior cervical corpectomy and fusion (ACCF) and anterior cervical discectomy and fusion (ACDF) for the treatment of two-level cervical spondylotic myelopathy (CSM). METHODS: A total of 71 consecutive patients who underwent ACCF or ACDF for two-level CSM in our institution from January 2014 to December 2016 were retrospectively reviewed. Of these patients, 30 (17 males, 13 females) were subjected to ACCF, and 41 (20 males, 21 females) were treated with ACDF. Perioperative data, radiographic parameters, clinical outcomes, and axial symptom occurrence were compared between the two groups. RESULTS: The average follow-up durations were 13.7 ± 3.9 months in the ACCF group and 13.4 ± 3.3 months in the ACDF group. The volume of blood loss was significantly lower in the ACDF group than in the ACCF group, and the operation time of the former was significantly shorter than that of the latter. The postoperative global lordotic angle and T1 slope were significantly larger in the ACCF group than in the ACDF group in each follow-up. The occurrence of postoperative axial symptoms was significantly lower in the ACDF group than in the ACCF group. CONCLUSION: The volume of blood loss was lower and the operation time was shorter in ACDF than in ACCF for the treatment of two-level CSM. Sagittal balance was better in the ACDF group than in the ACCF group, and this observation may lead to a reduced occurrence of axial symptoms.
