[Two unusual periosteal exotoses].
After maceration of the skeleton of 2 persons we found 2 different solitary exostoses; one at the sciatic tuber, in the other at the sciatic tuber, in the other at the ventral side of the distal fibula. The exostoses reach a length of 2 cm. Prescher (1987) described a cartilaginous exostosis with a length of 2 cm at the proximal tibia. In our cases the exostoses belong to the periosteal form. We consider them to be bony origins of ligaments: at the sciatic tuber--the bony origin of the sacrotuberal ligament, at the distal fibula--the bony origin of the peroneal compartment of the retinaculum mm extensorum inferius.
