From left to right, the left tibia, the right femur, the left humerus, the left ulna and the left radius.
A subadult left ulna measures 185 mm in length, suggesting an adolescent of 9 to 15 years.
The ulna and radius are connected at both ends.
Long bones (femur, tibia and ulna) were cleaned from their flesh and whole bone powder was obtained by crushing them.
The ulna is a dorso-ventrally flattened bone with a long groove on the proximal part of the ventral side for contact with the radius.
However, their hands were together in front of them, crossing one above the other at the level of the distal radii and ulnae, carpals, or metacarpals.
After this, the freed distal end is reattached to the proximal ulna with the formerly mentioned plate.
It is the proximal extremity of the ulna which is articulated with the humerus and constituting a part of the elbow articulation.
