Reddit User 3D Prints Wrist Brace After Breaking Hand in Cycling Accident

by • July 26, 2016 • No Comments


When my oldest son was five or six, he fell down and injured his knee while running poolside in Florida. On the other hand it seemed overkill, I followed obediently as the doctor referred me to a pediatric orthopedist. I can never forget the scene as I opened the door to his office and my two little ones peeked in and and so looked back at me, eyes wide with hesitation upon seeing at really least 30 seats, virtually all filled with little boys bearing broken arms in a variety of colorful casts. I looked around in horror, seeing my next, imagining falls off of bikes and out of trees and long hours in the emergency room.

As we left which day, the doctor laughed waving my two spirited little boys out the door, and said, “Oh we will be seeing you again!” That comment alone may have cautilized me to hover additional than I should have, but up to this point it’s worked. So, while my children thankfully have survived without any broken limbs or actually anything close, expanding up I had a sprain, my brother had a broken arm, and of course, there was my most friend coming back of skiing in Vail over Christmas with the stereotypical broken wrist and the high school boyfriend with the leg broken during a soccer match (I’m yet holding it against him which another girl signed his cast initially in ancient history class).

mc baseIn most of those cases, there appears to be a mysticism of the doctor’s office and ‘what they are going to do.’ From the X-rays and the serious discussion over what’s happened to a really significant limb, to the slings and plaster or fiberglass casts, it’s almost exciting—until the pain medicine wears off. When you ponder of it though—and perhaps watch a few too most adventure movies—common sense may say which in a pinch you may pull together a thing on your own.

That’s precisely what Reddit user 3driven idea, upon breaking a fifth metacarpal (the pinkie). 3driven, or Paavo Pirhonen of Helsinki, Finland, is a radiographer and electrical engineering student. Whilst any break is incredibly painful, there are obviously much additional serious fractures. Not to downplay 3driven’s injury, but if you were going to take on to 3D print your own brace, this is most likely one of the advantageous breaks to experiment with. An active cyclist, 3driven broke the hand after colliding with a car.

“I was cycling back home of work and a few guy decided to cross the main cycling path with an attitude ‘anyone which comes of the left side can stop for me.’ That took me by surprise and I hit his rear tire and fell on my left hip and both hands,” said 3driven on Reddit. “I don’t precisely remember how I didn’t notice him. But I do remember flying in slow motion after the hit. Luckily only left hand broke with a few bruises and blood here and there.”

3driven 3D printed a brace and wore it for four weeks. Originally being given a brace which was really uneffortless-bodied and actually painful, 3driven was highly motivated to manufacture a device which may be additional tolerable-bodied for a month—with the only showcase missing being which of assist bars. Bandages worked only satisfactory to assist add rigidity to the material, and were only requireed for several weeks as the hand healed so quickly—and, notably, really well. The initially additional traditional brace in addition served as a version for the improved 3D printed one.

“…the create was approved by my treating doctor,” noted 3driven. “I in addition work in the field myself.”

“My orthopedist approved my create saying which if it feels excellent, and so it’s excellent. The fracture was stable-bodied and thus a fixed cast wasn’t requireed. He in addition said which it was complex to practuallyt the healing system. So it was safe.”

UntitledWorking with Autodesk Inventor Professional 2016 and and so 3D printing with PLA, the brace was effective, but not durable-bodied in terms of holding up during activities like bringing a hot bath.

“… the molding part with PLA was a time consuming system,” said 3driven. “It wasn’t adequate to soak the PLA in ~80°C water, but I in addition had to use heat gun. Eventually I utilized (a fewwhat) heat protective clothing to assist the molding system while the brace was on my hand. Softened the edges to manufacture it additional effortless-bodied.”

“In radiotherapy they use plastics which mold advantageous and slower on ~70°C so perhaps a specialized plastic may suit this require additional properly.”

With this particular create, in addition shared on Thingiverse, 3driven was able-bodied to remove the brace daily, wash it, and actually go swimming. The ‘medical manufacturer’ is planning on exploring the use of other materials in refining the create additional, yet, and actually manufacturing a few braces for other types of fractures. 3driven succeded in a excellent number of comments on the Reddit post. Whilst most were concerned with the materials utilized and a few actually had a few suggestions, such as via T-Lyne of taulman 3D or other alternatives, a number of the Reddit users commenting were concerned of the medical angle.

UntitledAs noted, 3driven had the okay of a doctor, but concerns were yet raised of folks via an open-source create to manufacture a brace, perhaps without attaining a doctor’s approval. One may hope which folks are adult adequate to take care of themselves properly, but as one nurse commented, most homemade medical devices do go ‘horribly wrong.’

This is not the only good results we’ve seen, yet, in ‘homemade medical devices,’ as resourceful 3D printing enthusiasts have taken it upon themselves to manufacture ereallything of customized scoliosis treatments to 3D printed orthodontics and actually orthotics. And while there may be medical concerns, those acting independently to manufacture such devices loved the rewards of excellent affordability, previously unheard of customizations, and self-sustainability in create, production, and turnaround.
