Fracture of allograft interbody spacer resulting in post-operative radiculopathy: A case report

Figure 1 Post-operative radiographs showed good spinal alignment with hardware in good position and interbody spacer at each level is under the midsection of the disc space (arrows). A: Anteroposterior; B: Lateral.

Figure 2 Postoperative computed tomography scan. A: Sagittal view showed the main part of the allograft spacer in the disc space without clear view of broken fragment; B: Coronal view shows obvious fragment (arrow) in the right L5-S1 foramina; C: Axial view also shows obvious fragment (arrow) in the right L5-S1 foramina.

Figure 3 Fragments of prosthetic allograft interbody spacer extracted from right L5 neural foramen.

Figure 4 One-year post-operative radiographs showed interbody fusion and posterolateral fusion mass (arrows). A: Anteroposterior; B: Lateral.

Figure 5 One-year post-operative computed tomography-scan. A: Sagittal, B: Coronal; C: Axial. No foraminal bone fragment or stenosis (arrows).
