The enigma of the ulna in the primate wrist KU Leuven
The primate wrist is a highly complex structure which is important both in manipulation and locomotion. In both contexts, it must be able to provide the required stability to withstand loading, e.g. during power grips or quadrupedal locomotion, while at the same time allowing mobility to position the hand in the three-dimensional space. Part of the complexity comes from the fact that the wrist is not a single joint, but rather a combination ...
