Blade-Related Vertebral Fracture After Anterior Cervical Discectomy and Fusion with a Zero-Profile Cage

Abstract

Case: We present a case of a 79-year-old man with degenerative cervical myelopathy treated with anterior cervical discectomy and fusion (ACDF) using a zero-profile cage. Postoperatively, the patient experienced a rare complication of anchoring blade-related adjacent vertebral fracture leading to construct failure and recurrence of myelopathic symptoms, necessitating revision surgery. Conclusion: This case emphasizes the importance of precision in the surgical technique, specifically in the placement of Caspar pins and anchoring blades. It also underscores the need for a high index of suspicion for potential hardware-related complications in patients presenting with recurring symptoms post-ACDF, contributing to the understanding of such rare complications.
