Abstract
In short below-the-elbow stumps with insufficient muscle strength to flex the forearm through the normal range, it is very important to select suitable prosthesis. The wrong prosthesis may result in some clinical problems such as stump pain or abrasion. We reported two cases in which clinical problems were improved when using the Robin-Aids elbow hinge. Both patients had wide scarring around the stump, muscle atrophy of the upper limb, and limited range of motion in the elbow joint. They could perform standard active prosthesis techniques without trouble when using the Robin-Aids elbow hinge. Because the motion of the stump was used only for “locking or unlocking” when using the Robin-Aids elbow hinge, there was no need to burden the stump end with a heavy load. Though, in recent years, modern high-technology devices such as myoelectric hands have attracted people's attention, we should not forget old time-tested techniques which are as useful as modern ones.
