Final answer:
A prosthesis is a device used to replace a missing body part, commonly through joint replacement surgeries like hip and knee replacements. These prostheses can significantly improve mobility but have limited durability, sparking ongoing research into more lasting materials and advanced designs.
Step-by-step explanation:
A prosthesis is a device used to replace a missing body part. The progress in the science of prosthesis design, particularly in terms of artificial joints, has been remarkable. Common procedures such as hip and knee replacements involve highly invasive surgeries where worn or damaged parts of the joint are replaced with artificial components, also known as joint replacement or arthroplasty.
For instance, in a hip replacement surgery, the head and neck of the femur, and the acetabulum of the pelvis, are replaced with a ball-and-socket prosthesis. Although highly effective in restoring mobility and alleviating pain, these prostheses have limited durability and can wear out, especially in young or active individuals. Research continues into more durable materials and advanced technologies, such as carbon fiber and robotic prostheses, which hold the promise of longer-lasting solutions and even mind control capabilities.
