Prosthetics

Through research, evidence supports that prosthetics are modernized. Prosthetics also significantly help amputees, making them a necessity for those who need support, according to professionals in the field. Prosthetics are created from plastic and usually have small sensors to track electrical nerves within a limb, but with developed technology, prosthetics can do so much more. Prosthetics have developed to detect certain signals, and in order to prepare an individual for prosthetics, stimulations are used. Stimulation signals get sent to the three major nerves that usually carry sensory signals from the hand to the brain: the median, ulnar, and radial nerves. This stimulation is composed of balanced current flows in successive negative and…

After a three-year period from a lower limb surgery the veterans received, the group who received the prosthetic limb had fewer deaths than the group without the prosthetic limbs (Kurichi et al, 2015). In other words, the prosthetic limbs were a factor for declining deaths of veterans after they lost an extremity. Patients without prosthetics were more likely to die after a one-year period after the surgery. Ethically this means that the community should give veterans every means possible to…

When someone uses the term “prosthetics”, what is the first thing to come to mind? Is it an advanced robotic arm, or a simple plastic prosthetic hand, no more complicated than a mannequin’s? These shouldn’t necessarily be such opposites, but it is almost certainly true that the latter is more common than the former. Prosthetics have come an extremely long way since their induction. Pirates and peg legs tend to give us a reminder of how far we’ve come since the dark times where a prosthetic was a…

As technology continues to advance and possibilities are explored, these issues also continue to develop and become increasingly widespread. Consider the use of prosthetic limbs to restore limbs to those who lost them or have a condition preventing the development of the limb: individuals with prosthetic legs, for example, without denying the pain of having lost their limbs, need not be concerned with prosthetic fatigue. While the prosthesis may be mapped to their nerves to allow movement, it…

3-D Printing Prosthetics by Cameron Norman There are between 10 and 15 million amputees in the world. People who go through the hardship of losing a limb go through an incredible amount of pain each day. Not only this, but attempting to get a prosthetic limb that may allow them to function as they used to, is not only a difficult, costly process but it also does not lessen the emotional pain of having to live without a limb. With 3D Printing becoming an increasingly popular new technology,…

I am writing on the behalf of my patient, to document the medical necessity of a transfemoral prosthetic. Patient is a 17 year old male who underwent a transfemoral amputation six weeks ago secondary to osteosarcoma. Patient was independent in all activities and enjoyed playing basketball on the weekends prior to amputation. After high school, the patient intends to join the military. The patient’s goals are to resume prior level of function and participate in above mentioned activities. The…

hand transplant with bionic hands. Not only for the hand amputees, but also those with arms and legs amputated are able to have bionic prosthesis transplantation nowadays. The first hand transplant was performed in 1999, and the development of bionic prosthetic limbs…

Throughout my research I had a multitude of inquiries on how prosthetics could be used to expand the body. As I mentioned before, prosthetics move from identifying nerve signals being sent from the brain, as well as from contractions, but I wonder if they can just use contractions to make an entirely new limb that can be controlled by just by contracting certain muscles, as an external prosthetic. It could be an extra arm or leg, or even finger, and even if it wouldn’t be fully controlled, it…

professionals. One of these was an orthopedic surgeon, and during the time I spent watching his surgeries, I got the chance to witness two Total Knee Arthroscopies (TKAs). For my biomedical product, I chose to research a total knee prosthesis. This prosthetic has an old and very diverse history that centers mostly around the 1970s, but today has become a multibillion dollar industry with millions of patients undergoing TKA every year. The first total knee replacement was performed by Theophilus…

Prosthetic limbs have been giving people second chances at life for the last 150 years. In those 150 years prosthetic limbs have come a long way, but there is still many problems. Out of the many problems in the prosthetic limb industry, there is three main problems. The main problems include making the product available for the mass market, price of each limb, and the last problem for prosthetic limbs is advancing the technology. Although prosthetic limbs are essential for some of the people in…
