[Anatomical observation of the bony and ligamentous structures around the wrist--comparative study of the crab-eating monkey and the human].
So far as we surveyed in the literature, no articles had been published on precise studies on the bony and ligamentous structures around the wrist joint in crab-eating monkey. The authors made an observation about these particular anatomical structures by careful dissection of the 40 crab-eating monkeys, and the results were compared with those of three fresh human cadavers. The most significant differences were that the monkey had nine carpal bones (os centrale in addition), quite different configuration of the pisiform bone, no radio-scapho-capitate ligament, hypoplastic or no radio-scapho-lunate ligament, and different structure of the triangular fibro-cartilage complex. We discussed these differences from the view point of functional anatomy.
