Anterior cervical discectomy and fusion versus anterior cervical corpectomy and fusion for multilevel cervical spondylosis: a systematic review.

Abstract

INTRODUCTION:

There is considerable controversy as to which technique is best option for reconstruction after multilevel anterior decompression for cervical spondylosis. The aim of this study was to compare the clinical and radiographic results and complications of anterior cervical discectomy fusion (ACDF) and anterior cervical corpectomy fusion (ACCF) in the treatment of multi-level cervical spondylosis.

METHOD:

We reviewed and analyzed papers published from Jan 1969 to Dec 2010 regarding the comparison of ACDF and ACCF for multilevel cervical spondylosis. Statistical comparisons were made when appropriate.

RESULTS:

Twelve studies were included in this systematic review. Blood loss was greater for ACCF compared with ACDF. Similarly, the rate of graft dislodgement in ACCF was higher than that in ACDF. Nonunion rates were 18.4% for 2-level ACDF and 37.3% for 3-level ACDF, whereas nonfusion rates were 5.1% for single-level ACCF and 15.2% for 2-level ACCF. In addition, nonunion rates for three disc levels fused were much higher than that for two disc levels fused, regardless of discectomy or corpectomy. Clinical outcome was compared between ACDF and ACCF in nine studies. Of these, similar outcome was found between ACDF and ACCF in six studies, whereas three studies reported better outcome in ACCF compared with ACDF.

CONCLUSION:

Nonunion rates of ACDF are higher than those of ACCF for multilevel cervical spondylosis. Sometimes, clinical outcome of ACCF was better than ACDF for multilevel cervical spondylosis.
