| Study | N | Fusion Rate | Follow-Up | Notes |
| Current study | 201 | 68.7% | 12 mo | Presence of bony fusion based on independent evaluation of CT imaging at 12 mo |
| Cross et al21 | 19 | 78.9% | 12 mo | CT imaging; independently assessed and adjudicated for presence of bridging bone. Threaded implant fixation with decortication and graft placement |
| Kube et al3 | 17 | 88.2% | 12 mo | Thin-slice (<2 mm) CT imaging assessment of bony bridging across the sacroiliac joint and absence of lucency. Threaded implant fixation with decortication and graft placement |
| Abassi et al6 | 19 | 73.7% | 12 mo | CT imaging; independent assessment of solid bridging bone. Threaded implant fixation with decortication and graft placement |
