Paralyzed Woman Walks Again With 3D-Printed Robotic Exoskeleton 41
Zothecula writes "3D Systems, in collaboration with Ekso Bionics, has created a 3D-printed robotic exoskeleton that has restored the ability to walk in a woman paralyzed from the waist down. The Ekso-Suit was trialled and demonstrated by Amanda Boxtel, who was told by her doctor that she'd never walk again after a skiing accident in 1992. 'Designers from 3D Systems scanned her body, digitizing the contours of her spine, thighs, and shins, a process that helped them mold the robotic suit to her. Then they combined the suit with a set of mechanical actuators and controls made by EksoBionics. ... One problem that the designers faced in this case was that a paralyzed person like Boxtel often can't know that bruising is happening because she can't feel it. That's dangerous, Summit said, because undetected bruises or abrasions can become infected. "So we had to be very careful with creating geometry that would dodge the parts of the body that it had to dodge...[designing] parts that wouldn't impede circulation or cause bruising."'"

Fingers crossed for artificial vertebrae (Score:5, Interesting)
So as luck would have it, I'm one of those unlucky individuals for whom several vertebrae are deteriorating and/or growing bone spurs as I get older.
On thing that's surprised me is that it's not very common for surgeons to simply replace natural, deteriorating vertebrae with custom-shaped artificial ones. I don't know if it's because the surgery would be too complicated, or what.
But given all the problems for which 3D printing seems to be a solution, I'm hoping that it will hasten a fix for my back issues.

I think it would be possible to design a two-part artificial vertebrum (a doral part and a ventral part) that would press together and form a solid-enough substitute. But how would you get the old deteriorated vertebrum out without damaging the spine and spinal nerves?

Almost certainly.
Don't know, but I'll bet they'll be doing it within five years, and it'll be routine within ten years.

Leave it in place and have the replacement surround what is being replaced?
Not sure why the fascination with 3d printing here,
I don't imagine that the printer would be small enough to operate within the human body. ( someday... )
Otherwise, who cares how the replacement is formed

This is typically done by a large shaped autologous bone graft, although there are both Synex titanium expansion implants and artificial vertebral body of the biomimetic nano-hydroxyapatite/ polyamide 66 (n-HA/PA66) composites in use. Homologous attempt have frequently been unsuccessful due to immune rejection.
It's generally considered an experimental treatment in the U.S., which means that unless you get into a clinical trial, you are stuck paying out of pocket, since most insurance companies don't cover

The exoskeleton wasn't 3d printed. A liner for the exoskeleton was.
That's like getting 3d printed floor-mats in your car and saying "3d printed car!"
To obtain the perfect fit for Amanda, our designers used 3D scanning to digitize the contours of Amanda’s thighs, shins and spine and create a personalized three-dimensional base to inform the shape of the required assemblies. Sophisticated mechanical actuators and controls, manufactured and provided by Ekso Bionics, were then integrated with the more fluid components that were 3D printed from the customized scans to create the first ever bespoke suit.

I certainly agree that a custom fitted "suit" onto which the robotics attach is important.
Presumably it would have been done before with such arcane voodoo as plaster casts and latex molds.
This is undoubtedly an advance - but nobody 3D printed a robotic exoskeleton.

In the old days, they would have done that by molding and sculpting to her contours -- if they had the tech to make the exo suit respond to her commands. That's by far the hardest part.

If the answers to these questions are "yes", I think I might enjoy old age significantly more than I thought I would.

Hybrid in that the actuators and other mechanical parts are machined, and the "chassis" if you will, was printed. Basically, the parts that connect to her body are printed, and provide an interface to the machined bits that do the heavy lifting.
So I'm happy with calling it "hybrid". That just means it's not all machined/cast, and not all printed.
