For many, the difference between an orthosis and a prosthesis is difficult to grasp. Yet this difference is all that is obvious. In fact, the prosthesis is a device or device designed to replace a limb, part of an amputated limb, or a severely damaged or destroyed organ.
The orthosis, meanwhile, is used to support, immobilize or make more functional a member, which is why we find functional orthoses, discharge, prophylactic, support, control, correction, etc.
