Prosthetic socket fabrication

Regardless of the rectification and fabrication technique, the prosthetic socket is then trimmed proximally by hand to either allow complete or limited motion of the knee.

Many prosthetic facilities now use central fabrication to allow use of complex and expensive CAD-CAM technology without the need for each facility to purchase and maintain such equipment. With central fabrication, patient evaluation, casting, fitting, and delivery continue to be conducted in the prosthetist s office. The fabrication of the socket itself is done off-site and minimizes noise, dust, odors, and potential zoning law difficulties. As such, there is less need to hire technicians and theoretically more efficient use of the practitioner s time. Disadvantages of central fabrication include potential communication problems between the prosthetic and central fabrication facilities, shipping delays, and quality control. - ...
