Esophageal Injury in Patients with Ankylosing Spondylitis After Cervical Spine Trauma: Our Case Series and Narrative Review.

Introduction

Ankylosing spondylitis (AS) is a chronic inflammatory disorder that causes progressive ossification and fusion of the spine, particularly in the cervical region. This results in a rigid spinal column that is highly susceptible to unstable fractures, even after low-energy trauma. Cervical fractures in AS are often complex, extending through multiple spinal segments, and are associated with a high risk of neurological compromise. Esophageal injury associated with such fractures is rare but clinically significant, as the anatomical vicinity of the esophagus makes it vulnerable to direct trauma, delayed perforation, or secondary damage from fracture displacement and hardware failure. Aim: The purpose of this review is to present and highlight the clinical relevance of esophageal injury in cervical spine trauma among patients with AS, emphasizing the diagnostic challenges and surgical treatment in order to improve outcomes.

Results

Esophageal injuries in the context of AS-related cervical trauma are frequently overlooked due to subtle clinical manifestations such as dysphagia, subcutaneous emphysema, or covert signs of mediastinitis. Plain radiographs are insufficient to identify such complications; advanced imaging modalities are often required for detection. Management is complex and usually demands a multidisciplinary approach, involving both stabilization of the cervical spine and repair of the esophagus. Despite treatment efforts, these patients remain at increased risk for morbidity and mortality, mainly due to infection and sepsis.

Conclusions

Esophageal injury in cervical spine trauma associated with AS is an uncommon but life-threatening condition. Early recognition, comprehensive radiologic evaluation, and careful surgical planning are crucial for optimal management. Heightened clinical suspicion and awareness of this rare complication are essential to improve diagnostic accuracy and patient outcomes.
