A device for tracing contour of amputation stump and extremities: the contour-tracer.

There is a definite need to determine the exact size and shape of a stump or extremity in order to ascertain quickly any changes in contour and size, and at the same time to have tracings of the periodic reevaluations. A number of methods are presently used, such as the water displacement method, measuring the circumference of the stump or extremity at a number of points, and photography. None of these methods gives a simple rapid objective evaluation of the exact size and contour of the stump or extremity. In amputees it is extremely important to know when shrinkage and shaping have been fully accomplished so that the stump can be measured, a proper fitting prosthesis fabricated, and gait-training instituted. With the contour-tracer, described in this article, which we have used for many years, the exact size and shape of the stump or extremity can be readily secured by means of a simple tracing, which can be periodically repeated for permanent record purposes in order to evaluate objectively any changes. The contour-tracer consists of a right-angle device made of plastic or wood, into which has been inserted at the proper angle a ball-point or similar
