Toddler Gets Telescopic, Prosthetic Arm Bone

In a strange meeting of James Cameron and feel-good medical magic, a young boy who was diagnosed with a rare form of bone cancer a year ago is now cancer free, thanks to an experimental prosthetic replacement.

Mark Blinder was three years old when doctors determined he had Ewing's sarcoma, a rare form of bone cancer, in his arm's humerus bone. The Los Angeles Times reports that doctors initially tried chemotherapy, which alleviated the pain without reducing the size of the tumor. The only other option, it seemed, was amputation. Stanford University doctor Lawrence Rinsky, though, convinced the Blinders to try a less conventional option: a telescoping, artificial bone replacement from Biomet, Inc. Unlike most artificial bones, which tend to be only "partial" replacements, this particular procedure required the total removal of the cancer-ridden bone.

Scientists Rethink Just How Fingerprint Friction Works

The line between science and science-fiction continues to blur. When we were young, functional prosthetic limbs blew our minds. Now, college students can build them. Not only do these devices allow amputees more independence, but some promise to restore the sense of touch, at that. While these developments are amazing enough, a couple of British biomechanicists (that's right; it's a word) might have discovered a secret that could lead to even more advances, including allowing prosthetic hands to feel as well as natural hands do.

Roland Ennos and Peter Warman told ABC News their study shows that fingerprints reduce friction, which is a departure from the common belief that they increase grip. In their study, Ennos and Warman measured friction by sliding a weighted plastic sheet across the finger. The results showed that, as it does with most any substance, friction increased as more of the fingerprint's ridges of skin touched the plastic sheet. Accordingly, though, Ennos told ABC News that ink measurements taken during the study showed that fingerprints actually "reduce the contact area with the surface," and therefore actually reduce friction.

While this study does reveal a new truth about fingerprints, it does not limit or define the exact use of the creases and ridges on our fingers. To that end, Ennos did posit that fingerprints could decrease the likelihood of blisters by decreasing stress between the finger and rough surfaces. [From: ABC News]

Nifty Body Implants Give You Quasi-Super-Powers


With the imminent release of 'X-Men Origins: Wolverine,' everyone is getting a little super-hero envy (especially the guy in the video above). And who can blame them. There are certainly days when we wish we could heal our wounds and sprout indestructible metal claws from our hands, especially when some jackass with a Hummer parks across two spaces in the super market parking lot. Sadly, we're only human, and no amount of genetic engineering is going to let us shoot laser beams from our eyes.

Instead, we have to take what we can get from some advanced (if not quite Bionic Man level) implants and prosthetics. Science has given us prosthetic arms that are stronger and faster than our own, cochlear implants that are essentially hearing aides on steroids, and computers that read our brain waves allowing us to control robots and synthetic limbs (and Star Wars toys). But doctors and scientists aren't the only ones getting in on the action...

Students Create $20 Prosthetic Leg -- and It Works!


Now that the technology for advanced prosthetic limbs is achievable, students at Stanford University are trying to make it actually attainable for the average person around the globe.

Students in the school's Biomedical Device Design and Evaluation program started the JaipurKnee Project, and challenged themselves to create a fully-functioning prosthetic leg that could be manufactured for a very low price. Clearly, they were successful, creating the above, fully-functioning appendage for just $20 in parts and production costs.

In order to improve upon the sorts of limbs currently used in developing countries, the team first studied high-end titanium knee joints, which cost anywhere from $10,000 to $100,000. It then explored standard materials found in cheap prosthetics around the globe, and, eventually, came up with the design for a self-lubricating knee joint made from an oil-filled nylon polymer, significantly cutting production costs.

Prosthetic Finger Features Built-In USB Drive


Yanko Design is certainly home to many far-fetched, never-to-be-realized gadgets, but this so-called You-SB finger drive isn't one of them. In fact, it's already a bit behind the curve. Apparently, after losing a finger in a motorcycle accident last year, Jerry Jalava took advantage of the situation to get a 2GB USB drive installed in his new prosthetic finger, which he's happy to inform us stores the Billy Linux distribution and the movie 'Freddy Got Fingered.' The drive is even removable to allow for upgrades or different drives for different tasks. Can a pico-projector finger be far behind?

Man Well on Way to Having Video-Cam Eyeball


One Canadian filmmaker is striving to transform his false eye into a working video camera, according to a Reuters report at FoxNews.com.

Having lost an eye in a childhood shotgun accident, Rob Spence, 36, has called upon the kindness, and ingenuity, of strangers to help him in his self-proclaimed EyeBorg Project. With the help of engineering wunderkind Kosta Grammatis, inventor Dr. Steve Mann, and ocularist Phil Bowen, Spence seems to be well on his way to a functioning, wireless eyeball-cam.

That all depends of course, judging from the above video, on whether or not Grammatis can calm himself enough to solder correctly. [From: Fox News And: The EyeBorg Project]

Man Refuses to Give Up, Builds Own Prosthetic Arm

Man Refuses to Give Up, Builds Own Prosthetic Arm
Now just to be clear, we're not suggesting you ignore your doctor's advice, but we've got to admire Mark Lesek who refused to accept that he was unsuitable to receive a prosthetic arm.

Lesek lost his arm in a car accident five years ago but was told the amputation was too high for him to receive a usable prosthetic. He decided to ignore his Australian doctors and went to a different doctor who specially ordered an $80,000 prosthetic from Germany. However that arm broke down and proved to be unusable. To make matters worse, it cost $6,000 to send back to Germany for repairs.

Then he heard about osseointegration, a medical field involving implanting metal into bone. The doctors in Melbourne, Australia refused to perform the procedure, so Lesek flew to Sweden and went to the Branemark Osseointegration Centre where he was fitted with an $80,000 bolt that acts as a sort of artificial shoulder.

Immaculate Prosthetic Arm Makes Prosthetics... Sexy?


We never thought it would it come to this, but damn if that image above doesn't make the idea of having a prosthetic limb attractive. A pang first felt at the sight of Oscar Pistorius' Cheetah prosthetics is now fully engorged with visions of reckless play around farm equipment. The concept "immaculate" from Hans Alexander Huseklepp explores the idea of turning a handicap into a high-performance, cybernetic fashion statement. The neurological prosthetic is clad in technology-packed corian plates with dome-joints that offer a larger degree of freedom than that motherly-issued arm of yours. So enough with the flesh-colored plastics already, this is the biomechatronic future of the proud naturoid we'd like to see. Hell, we have to do something now that tattoos and piercings have gone mainstream.

Video: Teen Shows Off i-LIMB Prosthetic Hand


We've seen the i-LIMB plenty in the past, but we have to say that seeing it in action -- newly installed on teenager Evan Reynolds -- is pretty impressive. The prosthetic is so sensitive that Reynolds can grip a small bottle of water, no problem. We assure you: it's pretty cool.

Dog Gets $18K Bionic Leg

Dog Gets $10,000 Bionic Leg
We understand that dog is supposed to man's best friend, but we couldn't possibly imagine dropping nearly 20 grand on a bionic leg for one of our beloved pups. Don't get us wrong, we love our canine companions, but we could buy a pretty nice car or dig ourselves out of credit card debt with that kinda cash.

We assume that Reg Walker has money to spare since he spent £10,000 (a little more than $18,000) to fit his eight-and-a-half-year-old American Bulldog, Coal, with a specially-designed prosthetic limb. What makes the implant unique is that the titanium alloy used mimics animal hide, so the skin and bone will grow and seal the prosthetic to Coal's body.

The successful surgery means that Coal can return to his normal place by his owners side. "He goes everywhere with me - he goes on tour, he's the only dog to have allowed into Live 8 and the only dog that has ever been backstage at the Royal Albert Hall," Walker said.

That's one lucky dog! [From: Daily Mail]

Researchers Devise Neural Implant That Learns Over Time


Brain-machine interfaces have done quite a bit in helping handicapped individuals interact with prosthetic limbs, computers and other humans, but a new neural implant concocted at the University of Florida could make all those past devices look archaic.

Put simply, researchers have discovered a method that would enable brain-machine interfaces to "adapt to a person's behavior over time and use the knowledge to help complete a task more efficiently." Until now, the brain was the instrument doing all the talking while the computer simply accepted commands; with this method, "the computer could have a say in that conversation, too."

In all seriousness, this type of learning mechanism could be game-changing in the world of physical therapy, but we hesitate to give something mechanical inside of our body too much free will, ya dig? [Source: University of Florida News via Physorg]

Knee Brace Captures Energy, Powers Mobile Devices

Energy-capturing knee brace.

Every step you take could soon be the power source for your mobile phone, MP3 player or portable GPS device. A group of university researchers from the United States and Canada have developed a prototype knee brace that captures energy in a way that's similar to how some hybrid cars charge their batteries by converting energy while they brake.

"There is power to be harvested from various places in the body, and you can use that to generate electricity. The knee is probably the best place," said Arthur Kuo, an associate professor of mechanical engineering at the University of Michigan, in a statement released yesterday.

Kou and colleagues determined that when a person stops his or her lower leg from swinging forward into a step, the majority of the energy expended is just lost. The new prototype knee brace is built to capture and store that energy more efficiently than other human powered electricity generators. For example, a hand-crank generator requires 6.4 watts of metabolic power from a person to generate one watt of electricity because of inefficiencies -- but the knee brace requires less than one watt of metabolic power to produce one watt of electricity.

The challenge for the team of researchers, which also includes staff from Simon Fraser University in Canada and the University of Pittsburgh, is to make the device lighter so it doesn't tire the wearer. For now it is too bulky and heavy to be practical.

Kuo says that in the future, a light device could be very useful to hikers or soldiers who don't have quick access to an energy source. For people with a prosthetic limb, the energy capture device could be on one knee while a battery is implanted within the fake limb.

One Step Closer to the Bionic Man

bionic eyeThe 'Six MillionDollar Man' may be ready sooner than you think.

U.S. Scientists are conducting research that may one day lead to the creation of a bionic eye. This optical prosthetic could one day restore vision to those who suffer from glaucoma and other vision-inhibiting diseases.

After training monkeys to look at points of light, researchers inserted ultra-thin electrodes into their brains to stimulate the areas that process visual information. The scientists were able to cause the monkeys to move their eyes the same way they would when following the points of light.

Plenty of hurdles must be overcome, however. In order to create a high enough resolution image for humans to recognize patterns in the real world, the number of electrodes implanted will have to be increased by a factor of at least 100.

Eventually, the patient would wear a pair of glasses with a built-in digital camera that would wirelessly transmit data to a device inside the brain. This device would stimulate the electrodes implanted in the visual cortex to -- finally -- create images that represent what's going on in the real world.

Not quite Steve Austin's X-ray-like vision, but a mind-blowing possibility nontheless.
