Upper Extremity Prosthetics

Transradial (Below Elbow) A transradial prosthesis is an artificial limb that is fit to a person missing their limb below the elbow. Two main types of prostheses are available. Cable operated limbs work by attaching a harness and cable around the opposite shoulder of the damaged arm. The other form of prosthetics available are myoelectric arms. These work by sensing, via electrodes, when the muscles in the upper arm moves, causing an artificial hand to open or close. In the prosthetic industry a transradial prosthetic arm is often referred to as a “BE” or below elbow prosthesis.

Above Elbow (Transhumeral) A transhumeral prosthesis is an artificial limb that replaces an arm missing above the elbow. Transhumeral amputees experience some of the same problems as transfemoral amputees, due to the similar complexities associated with the movement of the elbow. This makes mimicking the correct motion with an artificial limb very challenging. In the prosthetic industry a transhumeral prosthesis is often referred to as a “AE” or above the elbow prosthesis.

Myoelectric Hand/Hook

Myoelectric-controlled arm prostheses are externally-powered prostheses, which means that they are not driven by the muscle strength of the patient, but with the aid of electric power. The word “Myo” is derived from Greek: mys (“muscle”)

A biochemical process generates electrical tension in the microvolt range every time a muscle contracts. This tension can be measured on the skin. This also applies to the muscles remaining after an amputation. With myoelectric arm prostheses, muscle tensions from the residual limb are usually read by two electrodes – small children start with one. The low myoelectrical impulses that lie in the microvolt range are then amplified and forwarded to the electronics of the prosthesis in the form of control signals. The great functional benefits of this prosthetic system have a decisive influence on rehabilitation results. Because myoelectric prostheses also offer an appealing design as well as wearer comfort, they have become established as the standard.

Michelangelo Hand

Myoelectric Elbows.  For upper-limb amputees, myoelectric-controlled prostheses offer the ultimate combination of function and natural appearance. Designed to mimic human anatomy and motion, electronic components are the closest alternative to an anatomical hand or arm. Thanks to constantly advancing technology, the latest prosthetic systems feature astonishing capabilities. Elbows that flex and extend with muscle signals so you can reach for a beverage and bring it to your lips.

Body Powered Above/Below Elbow Prostheses
