Page "Exoskeleton" Paragraph 21

Orthoses are a limited, medical form of exoskeleton.

An orthosis ( plural orthoses ) is a device which attaches to a limb, or the torso, to support the function or correct the shape of that limb or the spine.

Orthotics is the field dealing with orthoses, their use, and their manufacture.

An orthotist is a person who designs and fits orthoses.

A prosthesis ( plural prostheses ) is a device that substitutes for a missing part of a limb.

If the prosthesis is a hollow shell and self-carrying, it is exoskeletal.

If internal tubes are used in the device and the cover ( cosmesis ) to create the outside shape is made of a soft, non-carrying material, it is endoskeletal.

Prosthetics is the field that deals with prostheses, use, and their manufacture.

A prosthetist is a person who designs and fits prostheses.
