Bone resorption as a marker for delayed esophageal perforation post anterior cervical spine surgery: a retrospective analysis and call for increased vigilance

Delayed esophageal perforation following anterior cervical spine surgery (ACSS) is a rare but serious complication. This study is to investigate the clinical characteristics, diagnostic approaches, and treatment outcomes of delayed esophageal perforation following ACSS, with a focus on the role of bone resorption around internal fixations as a potential diagnostic indicator.
