Prostheses
Prostheses
Prostheses (pronounced pross-thee-sees, from the Greek prosthesis meaning "addition") are artificial devices that replace a missing body part, which may be lost through trauma, disease, or a condition present at birth. Prostheses are intended to restore the normal functions of the missing body part.
Types of Prostheses
Prostheses can be categorized into several types, including:
- Limb prostheses: These include both upper- and lower-extremity prostheses.
- Transradial prosthesis: A type of prosthesis that is used when a part of the arm below the elbow is missing.
- Transhumeral prosthesis: A type of prosthesis used when the arm is missing above the elbow.
- Transtibial prosthesis: A type of prosthesis used when the leg is missing below the knee.
- Transfemoral prosthesis: A type of prosthesis used when the leg is missing above the knee.
- Craniofacial prosthesis: Prostheses related to the face or skull.
- Somato Prosthesis: Prostheses that replace parts of the body located internally.
Materials and Construction
Prostheses are made from various materials, including plastics, metals, and composites. The choice of material depends on the intended use of the prosthesis, its desired appearance, and the patient's specific needs and lifestyle.
Fitting and Use
The process of fitting a prosthesis and learning to use it is called prosthetic rehabilitation. This process involves a team of healthcare professionals, including a prosthetist, physiotherapist, and occupational therapist.
