An above-knee (AK) prosthesis consists of a custom-made socket combined with a supportive frame, knee unit, pylon, and foot. Sometimes a suspension sleeve or harness may also be necessary.
Fitting and measurement Process
Although it varies considerably from person to person, new amputees usually begin the prosthetic fitting process a few weeks after surgery. A post-operative limb protector is often used during the first week following surgery.
Your Prosthetist takes measurement of your stump using the different and best kind of technology available.
The use of a temporary prosthesis has many advantages. It allows for swelling to subside and for the residual limb to heal completely, a process that can take up to six months and sometimes longer. A prosthetic sock or cushioning gel liner is worn between the socket and the body to protect the sensitive skin of the residual limb. Each day, the size of the residual limb will shrink as the swelling decreases. When this occurs, the user can add additional layers of socks to keep the socket from becoming too loose. If the socket gets too loose, a new test socket will be fabricated. Test sockets allow you to work together with a lower extremity specialist at Hanger Clinic to fine-tune features like contouring, upper trim lines and the placement of cutouts on the socket frame.
The temporary prosthesis typically does not have a cosmetic covering so it is easier for the prosthetist to make adjustments to the alignment and to the knee. People usually begin physical therapy and gait training while wearing the temporary prosthesis. During this time it is very important to locate and address any pressure spots or abrasions on the residual limb. When the volume of the residual limb stabilizes and the person has developed a steady level of activity, it’s usually time to move to a definitive prosthesis.
Your Prosthetist takes a final cast which is used to create Our thin, flexible socket slips into a supportive frame that is reinforced with lightweight carbon composite. Cutouts on the frame can help to relieve pressure points and allow muscles to naturally expand and contract during use.
