Table 4 Comparison of fusion rates in allograft, cancellous bone, and DBM subgroups of MISS
Fusion type | Allograft (Group A) (n = 7) | DBM (Group B) (n = 21) | Cancellous bone chips (Group C) (n = 15) | P-value |
|---|---|---|---|---|
a | 1 | 1 | 2 | 0.221 |
b | 5 | 14 | 19 | |
c | 1 | 0 | 0 | |
The rate of fusion (a + b) / (a + b + c) | 85% | 100% | 100% |
