A single corpectomy and strut grafting has been proposed as an alternative
to performing two-level adjacent discectomies with multiple grafts to produ
ce superior fusion rates. The purpose of this study was to compare the clin
ical and radiographic success of two-level discectomy and fusion with anter
ior cervical plate fixation compared with a single-level corpectomy. Fifty-
two patients were treated with either a two-level adjacent anterior cervica
l discectomy and fusion with cervical plating, or by a single-level corpect
omy and plate. Thirty-two patients had two-level discectomies, whereas 20 h
ad a single corpectomy and a strut graft (average follow-up was 3.6 years).
One patient had a pseudarthrosis from a single-level corpectomy and requir
ed subsequent surgery to obtain an osseous union. The fusion rates between
the two groups was not statistically significant (p = 0.385). The clinical
results of the surgeries were similar between the groups based on Odom's cr
iteria. The addition of cervical plates to either two-level discectomies or
single-level corpectomies yielded similar fusion and complication rates.
