thank you! for context, i'm basing my tech off myoelectric prosthesis, but it's set in the future so motor control and movement are nearly uninhibited. however, it's definitely not perfect and still impacts the character's lives.
- Would it ever be realistic for a large corporation to mass-produce "one size fits all" prosthetics? I'm assuming there would be major drawbacks but would it be a plausible solution under capitalism to an increased need for prosthetics? Or do you think in the future prosthetics will still need to be individually fitted?
- Would it be better for active amputees in the military to have one limb attachment that stays on nearly permanently, or switch between a variety of different specialized attachments in different situations?
- What would be the side effects of an adult wearing a permanent prosthesis long-term? Say for years, decades? (if wearing something permanently isn't plausible, i can def change that.)
- What are some things in fiction about amputees you wish you could see that aren't usually represented?
- Also, do you know of any amputee sensitivity readers? (transradial amputees if possible!) I'd love to run certain chapters by someone at some point (and again, 100% willing to pay).
thank you so much for your time! sorry this is really long
Sorry this took so long, I had finals this week!
Regarding āone-size-fits-allā prosthetics:
I would say that sockets (the part of the prosthesis that goes over the personās residual limb) do need to be custom. Everyoneās limbs are different sizes and shapes, and what works for one person might not work for another. Even if the socket is roughly the right shape, if thereās a little too much or too little pressure in one spot, that can cause major issues like ulcers over time.
As far as other parts of the prosthesis go, like hands or hooks for prosthetic arms and feet for prosthetic legs, those actually are already mass-produced! Prosthetists will decide what type, size, etc components are right for a given patient and then attach them to a custom socket to assemble a full prosthesis. The mass-produced components still arenāt one-size-fits-all though, because you want to make sure someoneās prosthetic foot is the same size as their good foot, for example.
I could maybe see all mass-produced components with osseointegration (no socket, thereās a piece that attaches directly to the bone and sticks out of the end of the limb, and then the rest of the prosthesis attaches to that), since thereās no socket, but I donāt know much about that.
One permanent attachment or several more specialized ones:
a lot of real amputees have multiple prostheses for different tasks! Someone might have one leg for normal day-to-day use and one for running, or a myoelectric arm and then a body-powered arm with a hook for more heavy-duty activity. Iāve even seen special prosthetic arms for gymnastics! Having multiple tends to work well today, since myoelectric technology isnāt perfect and some things are still easier without it, but if the technology is advanced enough that motor control is almost perfect, that might not be as necessary.
One thing I would keep in mind is the durability of the devices. If thereās a lot of delicate electrical parts, it might not work as well in the water, and also might not hold up as well to a lot of heavy use or chemical exposure. In that case, it might still be a good idea to have a less-advanced, more durable prosthesis they can switch to when needed.
long-term effects of wearing a prosthesis permanently
If the prostheses in this world still have sockets, I definitely would not recommend leaving them on 24/7!!! Itās really important to keep the liner/socks/inside of the socket/whateverās against your skin clean, so you donāt get any skin irritation or infections from sweat, bacteria, etc building up inside the socket, and you canāt do that if youāre not taking the prosthesis off. Itās also super important to keep an eye on your skin and check for things like irritation and blisters so they can be treated before they get bad. A little irritation that goes unnoticed and keeps getting exposed to sweat and bacteria in a dark socket without air can develop into a really nasty ulcer!
Peopleās limbs also change over time! Especially if they had a traumatic/acquired amputation (basically, werenāt born missing their limb), thereās a lot of swelling at first, and then also a ton of atrophy especially over the first year. A socket that initially fit well almost definitely wonāt still fit right 5-10 years later. Hell, sometimes peopleās limbs change day-to-day. There are times I have a lot of pizza for dinner and then have to wear one sock instead of two in my prosthesis the next day, because my leg swelled up a little. You need to be able to adjust for those little changes.
It also just doesnāt sound comfortable? Sockets can get pretty hot and sweaty, and itās nice to have some air on your limb at the end of the day.
I donāt know too much about osseointegrated prostheses, but as I understand it, the part that attaches directly to the bone stays attached permanently, but the rest of the prosthesis can detach from that. There wouldnāt be the same concerns about skin and the socket, and the main issue I can think of with keeping the prosthesis attached full-time would be that sleeping with a big metal leg on doesnāt sound the most comfortable? But I donāt know.
Things Iād like to see:
congenital amputees! limb loss not being presented as inherently this big tragedy! amputee jokes! So much media about amputees is about traumatic amputation and how itās this huge horrible devastating tragedy (and how Inspirational the amputee is for Overcoming it), and it definitely can be a tragedy for some people, but itās not for everyone, and Iām over here likeĀ āI was born without my foot? Itās just part of my life?ā
cool scifi prostheses where someone has actually thought about how they work behindĀ āthis would be cool!ā
a lot of scifi prostheses are either perfect replicas of human limbs (think Luke Skywalker) or just weapons (think of all the bad guys with sword arms, I think they show up in both Shang Chi and Black Panther? donāt quote me on that though, I havenāt seen either movie recently), and Iād like to see something a bit more realistic
youāre already doing great at this one!
different genre and technology level, but if you want an example of something that handled amputee representation well, How to Train Your Dragon is fantastic! Its amputees are just people (and dragons), and prosthetics are just normal parts of their lives
sorry, I donāt know any, transradial or otherwise
Donāt worry about the length -- as you can see, I like to talk about this stuff! And let me know if you have any more questions!
