ABSTRACT
INTRODUCTION:
Previous studies on patients with symptoms of spinal ligament ossification, including ossification of the posterior longitudinal ligament (OPLL) and ligamentum flavum (OLF), have not clarified whether obesity is a cause or consequence of these diseases and were limited by selection bias. Thus, we investigated the association between obesity and the prevalence of spinal ligament ossification in randomly selected asymptomatic subjects. MATERIALS ANDMETHODS:
Between April 2020 and March 2021, 622 asymptomatic Japanese subjects who underwent computed tomography of neck to pelvis for medical check-up purposes were included. All subjects were divided into the following three groups normal weight (body mass index [BMI] < 25 kg/m2), obese I (25 ≤ BMI < 30 kg/m2), and obese II (BMI ≥ 30 kg/m2). The relationship between factors affecting the presence of each spinal ligament ossification was evaluated using multivariate logistic regression analysis.RESULTS:
The proportion of subjects with thoracic OPLL was significantly higher in the obese II group than in the other two groups (vs. normal weight, P < 0.001; vs. obese I, P < 0.001). BMI was associated with the prevalence of OLF, cervical OPLL, thoracic OPLL, and ossification of the anterior longitudinal ligament (OALL). BMI was most significantly associated with the prevalence of thoracic OPLL (ß, 0.28; 95% confidence interval, 0.17-0.39).CONCLUSION:
BMI was associated with the prevalence of OALL, cervical OPLL, thoracic OPLL, and OLF in asymptomatic subjects, suggesting that obesity is associated with the development of heterotopic ossification of the spinal ligaments.Palavras-chave
