PLISCHUK, Marcos  and  INDA, Ana María. Difusse Idiopathic Skeletal Hyperostosis in a contemporary osteological collection (La Plata, Buenos Aires, Argentina). Rev. Mus. Antropol. [online]. 2015, vol.8, n.1, pp.147-156. ISSN 1852-060X.

The diffuse idiopathic skeletal hyperostosis (DISH) is a disease characterized by vertebral ankylosis, with massive ligaments and tendons ossification in the rest of the skeletal system. The aim of this study is to establish the prevalence of DISH in a well-documented and contemporary osteological collection, and to discuss pathognomonic features and associated risk factors. In order to establish the diagnosis, we registered, in 100 adults, the formation of bone blocks, with at least three fused vertebrae by ossification of the anterior vertebral ligament. It was also considered that were not compromise of the intervertebral spaces and sacroiliac joint. The extra-spinal area was analyzed as additional evidence because of enthesopathies.The results showed six individuals with DISH, with no significant differences between the sexes. The thoracic segment was the most affected, intervertebral spaces were not compromised in any way and the sacroiliac joint did not provide signs of ossification, while numerous enthesopathies were detected. The prevalences observed are due to the advanced age of the individuals analyzed and the nutritional characteristics of the reference population.
