Fusion by Spondylosis Rate
| 3 mo | 6 mo | 9 mo | 12 mo | |
|---|---|---|---|---|
| SBG fusion rate | 1/4 | 2/4 | 4/4 | 4/4 |
| Control fusion rate | 0/4 | 0/4 | 1/4 | 1/4 |
Number of levels, out of the total number of levels operated for the control and synthetic bone graft (SBG) group, was evaluated by computed tomography as fusion by spondylosis during the 12-month study period. Fusion rates were compared using the Fisher exact test for each timepoint.
SBG indicates synthetic bone graft.
Statistical significance was set at P<0.05.
