Upper Extremity Prosthetics

Transhumeral (AE)

Amputation occurring above the elbow.

Transradial (BE)

Amputation occurring below the elbow. 

MyoElectric (AE/BE)

“Myoelectric” is the term for electric properties of muscles. A myoelectric-controlled prosthesis is an externally powered artificial limb that you control with the electrical signals generated naturally by your own muscles.

Hand, wrist and elbow myoelectric components are available. With amputations above the elbow, a “hybrid prosthesis” may combine myoelectric-controlled components with body-powered components to control shoulder and/or elbow function. A skin-like glove covers the prosthesis for a natural appearance.

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

Wrists that bend and rotate, allowing you to position objects for convenient viewing and handling

Hands that can lug a suitcase or hold an egg without cracking it

Thumbs that can change orientation to over multiple hand positionsFIND OUT MORE

Mechanical (AE/BE)

Mechanical (Body Powered):

 This prosthesis uses body movements to operate the terminal device (hand or hook.) 

The prosthesis is connected to the body through the use of cables and harness. 

Using movements of the shoulders and the arms, the person can open and close the terminal device.

Passive (AE/BE)

This type of prosthesis can be used for all levels of amputation. It is used primarily to replace the body part that is missing. This promotes a healthy body image, and is also functional in that it can assist the sound side arm in activities such as holding or placing objects.


 Are prosthetics covered by insurance? 

  • While each individual’s health insurance will differ, most insurance providers will cover some if not all of the costs associated with your prosthesis. … For example, devices that are used for cosmetic rather than functional purposes or special prosthetic devices used for athletics may not be covered by insurance.

How much does a prosthetic arm weigh?

  • The weight of your artificial limb will depend on the type of limb and the components, but on average a below-knee prosthetic weighs 4 lbs and an above knee prosthetic weighs 8 lbs. A natural leg is approximately 1/6 of your bodyweight.
  • On average, an arm weighs about of your total body weight, depending on your gender, among other factors. A leg is about This means for a 150lb average human being, an arm weighs ~8lb and a leg weighs ~26lb.

How long does a prosthetic arm last?

  • Because a prosthesis is a significant investment, patients naturally want theirs to last as long as possible. A well-made prosthesis can last anywhere from a few months to a few years; three years is about average. However, the lifespan of a prosthesis will depend on several factors, and it varies for each patient.
