Translocation of Cervical Vertebral Body Replacement Device into the Esophagus.

Abstract

Expandable vertebrectomy devices are a key technology that has facilitated the adoption of minimally invasive approaches to spine oncology surgery. However, advanced technology still requires proper attention to surgical fundamentals. Here we illustrate a cage of a misplaced expandable vertebrectomy device causing esophageal perforation. Examination of the postoperative radiographs suggests that haptic feedback from the expandable technology may have given the false impression of bony engagement. This case highlights the need for proper mortise work and complete visualization of the segments to be instrumented even during minimally invasive surgery.
