| Abstract | Dysbaric or hyperbaric osteonecrosis (HBON) is a chronic skeletal complication resulting from repeated exposure to elevated ambient pressure followed by decompression, most commonly affecting divers and compressed-air workers. Despite long-standing recognition, the condition remains underdiagnosed due to its frequently asymptomatic early stages, delayed radiographic findings, and absence of standardized screening and management protocols. This narrative review synthesizes current evidence on the epidemiology, pathophysiology, clinical manifestations, diagnostic approaches, management strategies, prognosis, and emerging advancements in HBON. A comprehensive literature search of PubMed, Embase, and Scopus databases was conducted for studies published up to July 2025, supplemented by manual reference screening of relevant reviews and authoritative texts in diving medicine. The pathogenesis of HBON involves gas and lipid micro embolism, endothelial injury, and impaired intraosseous microcirculation, leading to ischemic bone damage, particularly in weight-bearing joints. Magnetic resonance imaging remains the gold standard for early detection, enabling identification of subclinical lesions and informed risk stratification. Management is stage-dependent, ranging from conservative monitoring and exposure modification in early disease to surgical interventions, including core decompression and joint arthroplasty in advanced stages. Prognosis is strongly influenced by lesion location and timing of diagnosis, with early detection associated with improved outcomes. Emerging advances in imaging techniques, regenerative therapies, and individualized decompression monitoring hold promise but require robust clinical validation. Greater awareness, early diagnosis, and multidisciplinary research efforts are essential to reduce long-term morbidity and occupational disability associated with hyperbaric osteonecrosis. |
