What is the difference between prosthesis and orthosis?

Prosthesis

* An artificial device that replaces a missing body part.

* Typically used to replace limbs, fingers, or toes that have been amputated.

* Can also be used to replace other body parts, such as eyes, ears, or teeth.

Examples of prostheses:

* Artificial limbs

* Artificial eyes

* Artificial ears

* Artificial teeth

* Breast implants

Orthosis

* A device that is used to support or correct a body part that is weak, injured, or deformed.

* Typically used to support the spine, limbs, or joints.

* Can also be used to correct foot problems, such as flat feet or bunions.

Examples of orthoses:

* Back braces

* Leg braces

* Knee braces

* Ankle braces

* Wrist braces

* Foot orthotics

Key differences between prostheses and orthoses:

* Prostheses replace missing body parts, while orthoses support or correct weak or injured body parts.

* Prostheses are typically more complex and expensive than orthoses.

* Orthoses are typically used for a shorter period of time than prostheses.

It is important to note that prostheses and orthoses are not mutually exclusive. A person may need to use both a prosthesis and an orthosis to achieve the best possible outcome. For example, a person who has had an amputation may use a prosthesis to replace the missing limb and an orthosis to support the remaining limb.
