Prosthesis
Definition: “A device designed to replace a missing part of the body or to make a part of the body work better.” (MedlinePlus.gov, 2023).
3D Printed Prosthesis: This method uses 3D printers to create body parts. These printers can provide comfort, appearance, and a lighter design for new prostheses.
Prosthesis is a technological innovation that has been around for over 3,000 years. However, the field of Prosthetics didn’t see advancements until the 1860s during the American Civil War. Limbs were in part made of rubber with attachments such as hooks. ( upmc.com, 2015 ).
But work isn’t done
Although the field of prosthetics has advanced significantly over the last 100 years, there is still work to be done. Accessibility to prostheses remains limited in certain socioeconomic groups. One area of particular need is children, due to high costs, insurance limitations, medical availability, and durability concerns. The average lifespan of a prosthesis is around three to five years. When developing prostheses for children, designers must consider both durability and the child's growth to ensure the child does not outgrow the device too quickly. Although the field has made remarkable progress, there is still work that needs to be done.

What is going on now?
Research and development teams are working on advancements in myoelectric sensors, which may enable prostheses to be multifunctional and intelligent. Sensors embedded in the skin could enhance signaling accuracy and functionality (Bates et al., 2020). These innovations are being implemented to create better-performing prostheses. Additionally, with the increasing use of advanced technology, artificial intelligence (AI) is also evolving to aid in the design and manufacturing of prostheses.

of prostheses are below the knee, making it the most common prosthesis limb.
