INTRODUCTION: Despite many studies on the prevalence of vertebral fractures (VFs), the VF prevalence at death in the Japanese population remains unclear.
MATERIALS AND METHODS: We evaluated the VF prevalence at death in a Japanese cohort using autopsy imaging computed tomography (AiCT). We enrolled 365 cadavers (188 men, 177 women, mean age of 84.6 years) donated for anatomical dissection at Shimane University School of Medicine. The VFs were diagnosed using the semiquantitative technique of Genant from the first cervical vertebra to the fifth lumbar vertebra.
RESULTS: The overall VF prevalence was 69.6% (58.5%/81.4% in men/women), of which 46.0% (29.8%/63.3% in men/women) had thoracic VFs, and 58.1% (50.5%/66.1% in men/women) had lumbar VFs. The most frequent fracture site was lumbar spine 1 (L1) with 31.5% (22.9%/40.7% in men/women), followed by thoracic spine 12 (T12) with 31.0% (20.7%/41.8% in men/women). In terms of severity, 3.8% (4.8%/2.8% in men/women), 23.8% (27.1%/20.3% in men/women), and 41.9% (26.6%/58.2% in men/women) were Grades 1, 2, and 3. The VFs from T3 to L5 and of Grade 3 severity were significantly higher in women. VF and Grade 3 fractures were associated with a history of surgical intervention for femoral neck fractures. VFs were not associated with the following underlying causes of death: cancer, heart disease, senile death, cerebrovascular disease, pneumonia, and aspiration pneumonia.
CONCLUSION: The VF prevalence at death, assessed by AiCT in cadavers donated for anatomical dissection, was higher in both men and women compared with previous studies conducted on individuals aged ≥ 80 years in Japan.
