Sentinel sign in standalone anterior cervical fusion: Outcomes and fusion rate

J Orthop. 2018 Aug 24;15(4):935-939. doi: 10.1016/j.jor.2018.08.027. eCollection 2018 Dec.


Background: The authors aim to demonstrate the feasibility, outcomes and fusion rate of a standalone PEEK cage in the outpatient setting.

Methods: 48 consecutive patients undergoing standalone ACDF (S-ACDF) (Group 1) were compared to control group of 49 patients who had ACDF with ACP (Group 2).

Results: Analysis of follow-up at the one year period postoperative outcomes between groups 1 and 2 demonstrated no intergroup statistical significant difference in VAS neck, arm and NDI scores p = 0.414, 0.06 and p = 0.328 respectively.

Conclusion: We conclude that S-ACDF can be safely done in an ambulatory surgery center with satisfactory clinical and patient-reported outcomes.
