[Diffuse idiopathic skeletal hyperostosis. Review of diagnostic criteria and analysis of 915 cases].
DISH is a common systemic skeletal disease, probably of dysmetabolic and/or degenerative origin, yet of unknown etiology. It is observed in middle-aged or elderly patients of both sexes, and is characterized by ossification of the anterior longitudinal ligament on the antero-lateral aspect of the spine, and by ossifying enthesopathy, in both the central and the peripheral skeleton. Diagnosis is solely based on radiographic abnormalities, according to the so-called Resnick criteria. In the present study, the spines of 915 patients (414 males, 501 females, mean age: 65 years) were considered, and the peripheral entheses (heel, patella and elbow) of 494 of them (234 males and 260 females). The incidence of DISH was 14.09% (129 cases): 17.6% in males (73 cases) and 11.7% in females (56 cases). DISH strikes in the VI and VII decades of life most. The most affected sites of the spine were: the dorsal portion (100%), especially in the D7-D11 segment (93%); the lumbar spine in L1-L3 (81%), and the cervical spine, in the C5-C7 segment (69%). Peripheral areas of involvement were: pelvis (90%), heel (76%), elbow (46%) and knee (29%). The symptoms of DISH must be promptly detected: the disease is not asymptomatic, but presents with pain and stiffness in the spine, recurrent tendinitis and bursitis, and myelopathy.
