Prosthesis
An artificial device that replaces a missing or damaged part of the body, from a hip implant to a dental or limb prosthesis. Here is what it is, the main types, what they are made of, and what to ask when treatment is abroad.
An artificial replacement part.
A prosthesis is a manufactured device that replaces a missing or damaged body part, to restore function, appearance, or both.
A prosthesis is an artificial device that replaces a part of the body that is missing or no longer works as it should. The word covers a wide range. It includes joint replacements such as an artificial hip or knee, dental devices such as crowns, bridges and dentures, breast implants used in reconstruction or augmentation, and external devices such as an artificial limb or eye. The plural is prostheses, and the related word prosthetics is the field that designs and fits them.
Prostheses are broadly internal or external. An internal one is implanted during surgery and stays in the body, like a hip implant or a dental implant fixture. An external one is worn and can be removed, like a limb prosthesis or a removable denture. They are made from materials chosen to work safely in or on the body and to last, commonly titanium and other metal alloys, medical grade ceramics, and durable plastics and silicones. The specific design and material are matched to the part being replaced and to the person.
Most prostheses work well, but they are devices, and devices can wear, loosen, or occasionally fail, so many need monitoring and some need replacing or revising over time. The make and model matter, because that is what records, recalls and future repairs are traced through. Keeping the documentation for exactly which device was used in your body is part of staying safe with one, especially if a problem appears years later.
Keep the device record.
When a prosthesis is fitted abroad, the single most useful thing you can take home is a clear record of the exact device. Ask for the make, model, size, batch or serial number, and the implant card or certificate where one exists. If there is ever a recall, or you need a revision, repair or imaging years later, a clinician at home will want to know precisely what is inside you. Without that paperwork, sorting out a problem becomes much harder.
Beyond the record, ask what the device is, why that one was chosen, what its expected lifespan is, and how follow up and revisions would work once you are home, since many implants need monitoring over years rather than weeks. Be wary of unusually cheap implants or vague answers about what will be used, because counterfeit and substandard devices are a known risk. A clinic that documents the device fully and explains the long term plan is treating the prosthesis as the lasting commitment it is.

Want clinics that document the device?
Send one brief and we route it to vetted clinics that record exactly which implant they use and plan your follow up. You choose, with no pressure.
How we make money: the guides are free and no clinic can pay to be named, ranked or recommended — we never name clinics. Get Matched is an optional service that helps keep the guides free and independent of any one clinic; using it is always your choice and you are never charged. How this works.
