Abstract
BACKGROUND AND OBJECTIVE: Ankylosing spondylitis (AS) spinal fractures pose unique diagnostic and therapeutic challenges due to the altered biomechanics, rigid ankylosed spine, and risk for extensive neurologic injury. The optimal practice is not established with rising clinical occurrences. This article aims to review the current literature regarding diagnosis, classification, and operative and non-operative treatment paradigms of spinal fractures due to AS in adults and present a cohesive perspective to facilitate evidence-based clinical practice. METHODS: A narrative systematic review was conducted on the basis of the PubMed database, including English-language papers from January 2000 to May 2025. Keywords included "AS", "spinal fracture", "vertebral trauma", "surgical management", and "neurological outcomes". Studies identified were evaluated based on clinical relevance, level of evidence, and representation of evolving concepts in diagnosis and management. KEY CONTENT AND FINDINGS: The review discusses the specific biomechanical frailties of the ankylosed spine, recent classification methods like AO Spine and Denis classifications, and recent imaging modalities for diagnosis. It highlights operative decision-making approaches, posterior-only, anterior, and combination, in fracture morphology, neurologic status, and patient comorbidities. It discusses perioperative concerns such as positioning issues, blood loss, and complications like hardware failure and infection. Four summary tables provide insight into imaging preference, surgical interventions, outcomes, and complication profiles. CONCLUSIONS: Prompt diagnosis and personalized treatment of AS-related spinal fractures are essential to reducing morbidity and mortality. Emerging literature supports the use of posterior-only methods in selected cases, but highly context-specific surgical choices must remain. The review stresses the importance of prospective studies as a guide to standard treatment protocols and improved outcomes for this difficult patient group.
