Anatomical observations of spurs of the tuber ischiadicum.
In a study of 101 human pelves, 8 pelves (only males) were found with ossification in the area of the ligamentum sacrotuberale. Seven of these showed a characteristic and similar morphology and could be considered to be periosteal exostoses. The term "spur of the tuber ischiadicum" is proposed for this manifestation. There was a single case of metaplastic ossification, possibly of traumatic origin. Hence, not all ossifications in the area of the ligamentum sacrotuberale can summarily be classified as a spur of the tuber ischiadicum; careful discrimination is essential in every case.
