The file for the mesh plus the materials is available. It is high-resolution and anatomically correct up to some degree. Not only does it include the hand it includes the radius and ulna, two bones that make up the forearm. Feel free to alter it and render it in your image.
To access it, click on the link provided
http://cid-ea40627868c69dba.office.live.com/browse.aspx/.Public?lc.=4105 and download the .blend file labeled as 'skeletal hand.' In some cases, because the file is 4.8 mb, it might prove to big. So, I will be uploading a zipped or compressed version shortly.
