Figure 2.

Representative μCTs at 8 weeks in coronal and sagittal planes demonstrating differences in bone formation between viable (A), partially devitalized (B), and devitalized (C) autograft groups. Viable (A) and partially devitalized (B) autografts had bilateral fusions bridging the TPs in spines graded as fused. Devitalized (C) autograft lacked bone bridging between the TPs. μCT indicates microcomputed tomography; TP, transverse process.
