Glossary

It's fun to learn new, big words. Knowing how to talk about your brace or prosthetic limb can help you express yourself. This glossary includes words that you may hear a lot when people are talking about your brace or prosthetic limb. Imagine how surprised the grown ups will be when you use these big words too!

Ankle Foot Orthosis (AFO)

Bilateral

Brace

Cerebral Palsy (CP)
Cerebral palsy is a condition that a person is born with. A person with CP has a brain that works in a special way and this makes the body move in a special way. CP can also affect other activities, like speaking. Sometimes a person with CP can use bracing to help support body parts, like the ankle and foot.
Endoskeletal Prosthesis
In an endoskeletal prosthesis, there is no hard, outer shell covering the prosthetic parts, like the foot or knee. Sometimes you can see the prosthetic parts in an endoskeletal prosthesis, while sometimes they are covered for a soft, foam cover.
Exoskeletal Prosthesis
An exoskeletal prosthesis is a prosthesis that is covered in a hard, outer shell. EXO means 'outside'. It's like having bones on the outside!
Fibula Hemimelia
​When a child is born with fibula hemimelia, the fibula is either short or missing. 
Myoelectric
A myoelectric prosthesis uses signals from muscles (myo) to activate electrodes (electric) in a computerized prosthesis. The electrodes are externally placed against certain muscles that, when flexed (sometimes referred to as 'fired), send signals to the prosthetic elbow and/or hand. Those signals tell the computerized component how to move. For example, firing a certain muscle in the residual limb will tell a prosthetic hand to open or close its grip. 
Orthotist
​An orthotist is a person who designs and makes orthotic bracing for people (and sometimes even for pets). An orthotist uses a combination of science and art to create each brace. To become an orthotist, a person has to go to college and receive extra schooling and practice. 
Prosthesis
A prosthesis is an artificial limb used by a person who is missing a whole limb or part of a limb. Some people might call a prosthesis a 'robot' limb, or 'bionic' limb.

Proximal Femoral Focal Deficiency (PFFD)
PFFD is a condition that a person is born with. PFFD means that a person's hips and thighs do not fully form before birth. A person may have PFFD in one or both legs. There are many different types of PFFD and many different ways to help that person be active.

The residual limb is the part of the limb that you still have, even if part of the limb is missing. 
Supramalleolar Orthosis (SMO)
An SMO is a brace that support the foot just above the ankle.
Tibial Hemimelia
