Residual Motion and Graft Type Do Not Influence Patient-reported Outcomes Following One- or Two-level Anterior Cervical Discectomy and Fusion
Conclusion. Allograft may result in slightly more residual motion at the arthrodesis site 1 year after ACDF. However, there is minimal evidence that PROs are adversely affected by slightly increased residual motion, suggesting that the current definition of pseudarthrosis correlates poorly with clinically significant findings. Additionally, autograft appears to result in superior outcomes in patients who smoke. Level of Evidence: 2 (Source: Spine)

Fracture of the Dens Axis Due to Spinal Manifestation of Sarcoidosis: Treatment Option and Review of the Literature
Conclusion Sarcoidosis-induced odontoid fractures can be managed successfully using a semiconservative approach, consisting of transoral-transmucosal, minimally invasive surgical procedure for debridement of the lesion and transplantation of cancellous bone with additional halo-immobilization. Permanent fusion of C1-2 with loss of the cervical range of motion is avoided.
