Answer

In a study by Mori et al of 3013 Japanese patients (1261 females and 1752 males) with a mean age of 65 years, the computed tomography– based prevalence of thoracic DISH was 8.7%. [17] The posterior longitudinal ligament of the cervical spine is ossified in 2% of Japanese individuals but in only 0.16% of white persons. [18] The anterior longitudinal ligament is calcified in 24% of patients with posterior longitudinal ligament ossification. [19]

DISH was reported in 17% of individuals in the Netherlands, paradoxically with male predominance. [20] A South African study of hospitalized patients 40 years of age and older found that the prevalence of DISH in African blacks was 3.8% in men and 4.2% in women; the prevalence rose with increasing age, from 1% in the 40-49 year age group to 13.6% in those over 70 years.
