Prosthesis: Difference between revisions

After the Second World War a team at the [[University of California, Berkeley]] including [[James Foort]] and C.W. Radcliff helped to develop the quadrilateral socket by developing a jig fitting system for amputations above the knee. Socket technology for lower extremity limbs saw a further revolution during the 1980s when John Sabolich C.P.O., invented the Contoured Adducted Trochanteric-Controlled Alignment Method (CATCAM) socket, later to evolve into the Sabolich Socket. He followed the direction of Ivan Long and Ossur Christensen as they developed alternatives to the quadrilateral socket, which in turn followed the open ended plug socket, created from wood.<ref name="Long">{{cite journal |last1=Long |first1=Ivan A. |title=Normal Shape-Normal Alignment (NSNA) Above-Knee Prosthesis |via= O&P Virtual Library |journal=Clinical Prosthetics & Orthotics |year=1985 |volume=9 |issue=4 |pages=9–14 |url=http://www.oandplibrary.org/cpo/1985_04_009.asp }}</ref> The advancement was due to the difference in the socket to patient contact model. Prior to this, sockets were made in the shape of a square shape with no specialized containment for muscular tissue. New designs thus help to lock in the bony anatomy, locking it into place and distributing the weight evenly over the existing limb as well as the musculature of the patient. Ischial containment is well known and used today by many prosthetist to help in patient care. Variations of the ischial containment socket thus exists and each socket is tailored to the specific needs of the patient. Others who contributed to socket development and changes over the years include Tim Staats, Chris Hoyt, and Frank Gottschalk. Gottschalk disputed the efficacy of the CAT-CAM socket- insisting the surgical procedure done by the amputation surgeon was most important to prepare the amputee for good use of a prosthesis of any type socket design.<ref name="Gottschalk-Kourosh-Stills">{{cite journal |last1=Gottschalk |first1=Frank A. |last2=Kourosh |first2=Sohrab |last3=Stills |first3=Melvin |last4=McClellan |first4=Bruce |last5=Roberts |first5=Jim |title=Does Socket Configuration Influence the Position of the Femur in Above-Knee Amputation? |journal=Journal of Prosthetics and Orthotics |date=October 1989 |volume=2 |issue=1 |pages=94 |doi=10.1097/00008526-198910000-00009 }}</ref>
