CAD/CAM transtibial prosthetic sockets from central fabrication facilities: How accurate are they?

Sockets made by central fabrication facilities with computer-aided fabrication equipment were tested. We carefully measured the shapes of the sockets using a custom instrument and then compared them with the computer file shapes. Results showed that some central fabrication facilities consistently made sockets that matched the computer files shapes quite well, some consistently made sockets that did not, and some made sockets that matched quite well some of the time. This study is relevant to the prosthetics industry because the results help provide insight into limitations in central fabrication and thus identify areas of needed improvement.
