A Manual for Below-Knee Amputees

The Syme Prosthesis

The prosthesis for the patient with Syme's amputation is similar to the below-knee prosthesis except that the socket also serves as the shank. Because of the short space between the end of the stump and the floor, a special type of foot, usually a modification of one of the popular designs, has to be used. Also, because of the shape of the stump, no extra provision for suspension is necessary.

Two types of sockets are in general use: the plastic socket with an expandable liner, and the plastic socket with a medial opening. Both types were designed for easy entry, yet take advantage of the shape of the stump to provide suspension.

Although the end of the stump can take more weight, or load, than in the case of below-knee amputees, it is necessary to shape the upper part of the socket like the PTB so that much of the load can be taken at the knee during walking and standing.
