The radius has two plastic bolts and ulna has one. The isolated and sutured extensor carpi radialis tendons are clearly seen at the bottom of the image.

The isolated radius bone (right) was derived from the initial MR image (left), as would also be the case for the scaphoid and lunate.

All images are oriented with dorsal at top, lunate fossa to the right, and scaphoid fossa to the left. Note the consistent dorsal contact measured by the Tekscan sensor and the MRI-based models.

The asterisks and braces indicate which model measurements met the validation criterion for total joint force and with respect to which experimental measures.

Model data matches the direct measurements well in all cases, and the Tekscan contact area is also consistently similar (except for S1).
