title: [Adult degenerative and senile degenerative hyperostosis triangularis ilii (author's transl)].
abstract: A randomized study of 2000 patients (1000 males, 1000 females) revealed two forms of the triangular hyperostosis of the ilium in female patients. The hyperostosis triangularis ilii, HTI, is also known as osteitis condensans. One form of HTI concerning women under the age of 50 is called the adult generative HTI, the other beyond the age of 50 senile degenerative HTI. These two forms are not evident in male patients. The 3.05% incidence of HTI in adults appeared to be higher than presumed till now. The sex incidence male/female of 1:1.6 diverges considerably from preceding investigations. Histomorphological studies of two autopsies of cases of senile degenerative HTI revealed no signs of inflammation. Statistical correlations of HTI with other chronic diseases of the pelvis and hip could doubtlessly and generally be established only for osteoarthrosis of the sacro-iliac joints in females beyond the age of 50 and in males as a matter of principle.
