Two-level, three-level ACCF for cervical spondylotic myelopathy offer similar results

Despite having a higher estimated blood loss, two-level anterior cervical corpectomy and fusion offers similar results in the treatment of cervical spondylotic myelopathy compared to three-level anterior cervical discectomy and fusion, according to the results in a recently published study.
Researchers analyzed 20 patients who underwent two-level anterior cervical corpectomy and fusion (ACCF) and 35 patients who underwent three-level anterior cervical discectomy and fusion for cervical spondylotic myelopathy between 2006 and 2012. All procedures were performed by one or two surgeons.
Patients in the two-level ACCF group had more estimated blood loss in their procedures and a longer hospital stay compared with three-level ACDF (7.2 days vs. 4.9 days, P = .048), but a subgroup of patients without posterior spinal fusion were found to have similar length of stays (3.1 days for ACCF vs. 4.4 days for ACDF, P = 0.267).
Researchers noted the postoperative sagittal Cobb angles were statistically similar between the two groups, with the mean angle in the ACCF group at 7.2° compared to 12.1° for the ACDF group (P = .173).
Additionally, both groups experienced similar postoperative cervical lordosis, pain relief, neurological improvements, radiographic pseudarthrosis rates and operative adjacent-segment disease rates, according to the study data.
Researchers concluded that except for blood loss, both two-level ACCF and three-level ACDF had similar postoperative outcomes when posterior spinal fusion was not involved. – by Robert Linnehan
