In medicine, a prosthesis (pl.: prostheses; from Ancient Greek: πρόσθεσις, romanized: prósthesis, lit. 'addition, application, attachment'), [1] or a prosthetic implant, [2] [3] is an artificial device that replaces a missing body part, which may be lost through physical trauma, disease, or a condition present at birth (congenital disorder).
This was further modified into the Delta III prosthesis in 1991. As Grammont's reverse ball and socket prosthesis gained popularity and began demonstrating reliable outcomes, [ 15 ] he subsequently developed what would be known as the “Grammont Principles”, [ 16 ] which were a set of rules that explained why his prosthesis was effective and ...
The prosthesis may need to be replaced due to complications such as infection or prosthetic fracture. Replacement may be done in one single surgical session. Alternatively, an initial surgery may be performed to remove previous prosthetic material, and the new prosthesis is then inserted in a separate surgery at a later time.
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
Arthroplasty presents various and continuous challenges to the engineer and surgeon. The prosthesis selected must be nontoxic yet resistant, compatible and durable. Meeting all these criteria usually means that the prosthesis will not last 10–20 years. 75% of artificial knees will last 20 years and 90% will last 10 years. [3]
The accident that broke 10-year-old Princess Igbinosa's right leg could have crushed her dreams of becoming a model in a country where not many can afford prosthetics to cope with life and fight ...
Rotationplasty allows the use of the knee joint, whereas amputation would result in loss of that joint. Therefore, it provides a better attachment point and range of motion for a prosthetic limb. As a result, children who have had rotationplasty can play sports, run, climb, and do more than would be possible with a jointless prosthetic.
