In order to investigate further the incidence, sex frequency, nature and location of fusion in the sacroiliac joint, the joint of one side was removed from 49 embalmed cadavers, aged 52–89 years, 22 male and 27 female, and examined by A/P radiography, radiography of transverse slices through the joint, stereomicroscopy, and histology. Fusion of the joint occurred both by synostosis and by fibrous interconnections. Synostosis occurred in a para‐articular form, especially along the ventral border and in the cranial limb of the joint and also in an intra‐articular form. Fibrous fusion was found more commonly in the caudal limb of the joint. Radiography of transverse slices revealed a high incidence of synostosis (60.8%). A/P radiography, on the other hand, indicated a much lower incidence of joints showing clear evidence of synostosis (18.4%), but if to this were added those joints showing radiographic changes involving the possibility of some degree of fusion then a comparable incidence (65.3%) was obtained. Both methods revealed a higher frequency of synostosis in the male, although it did in fact occur quite frequently in females; 66.7% in male 53.8% in females when assessed by radiography of transverse slices.
