New Body Parts

Hip Replacement

As I gear up for Hip Replacement #2, my sister sent this funny comic to me. 


I heard that something like a million joint replacements are now done in the U.S. every year. 


And these procedures are expected to increase precipitously with projections by 2030 of:


– 3.48 million knee replacements (a factor of almost 7 times)


– 572,000 hip replacements (an almost 2-fold increase)


This also means that revision surgeries will start to rise rapidly as replacements wear out or are in need of replacement themselves. 


Thank G-d that they have these procedures to help people–I don’t know how people lived with the incessant pain and degenerative mobility even a generation ago. 


What’s it like to have a body part inserted to augment your own?


Just ask this horse! 😉

Robot Man

Robot Man

Don’t know exactly what it is about this little robot guy, but I really liked it.

The simplicity of the body and limbs joined by the connector joints and the head as just a clear crown on the rest.

To me, it looked relatively realistic as how robots of the future might actually look.

Humanoid, but so sleek that they are us but in many ways a step up from our aging selves.

Perhaps, someday the brains of humans and the bodies of machines will really come together in a better alternative to ourselves.

Living (indefinitely) longer and even pain free in bodies that carry mind and soul into the future.

1St Day Post-Op

1St Day Post-Op

So surgery was yesterday around 11 am.

I was asleep under anesthesia before I ever even got to the operating room, so can’t remember a thing, which is probably good since I hear that a lot of power tools are involved.

Right before, my wife kissed me and told me that the female nurses were all flirting with me–ha!

After the surgery, I was groggy like crazy.

When the nurse asked me if I knew what year it was, I blurted out “1993!”

Aside from the general anesthesia, I had some sort of nerve block.

Thanks G-d that has made the pain minimal to zero even.

The nurse this morning gave me a percocet in anticipation of the pain with physical therapy today–so I apologize if this blog is a little loopy today.

So far, although very stiff around the surgical area, I have already sat up, got up, even walked a little down the hospital hallway.

Waiting for more PT and OT this afternoon.

I just want to say thank you to G-d, the surgeon, the anesthesiologist, all the nurses, and my wife and kids and other family and friends for taking such good care of and for all their thoughts and prayers.

One friend, even called me the bionic man this morning.

It’s been a really tough year with the loss of my mom in January and my dad not being well in the hospital and now in a facility to get him back on his feet again too.

And so far, my wife has been doing great keeping us going with only one big stress attack and trip to the ER to show for it. 😉

Restoring Hearing Using Bionics

Restoring Hearing Using Bionics

A mother wrote in the Wall Street Journal yesterday about the miracle of Cochlear Implants.

Lydia Denworth described when her 2-year old son, who is deaf, got these implants and how now he is now able to attend 5th grade in a “mainstream school” and is “nearly indistinguishable from the other children.”

These implants allow her son, Alex, to have a conversation with another child about the hearing device that “can open up the world of sound and spoken language.”

Denworth states at the end of the editorial, “Moments like that make me deeply grateful for the technology.”

For me, reading this was an opportunity to go learn about the amazing bionics that has already restored hearing to 320,000 people!

While hearing aids amplify sounds and make them louder, they don’t resolve permanent damage to the inner ear.

A cochlear implant bypasses the damage by receiving sounds in a microphone, digitizing them, and converting them to electrical impulses that are sent directly via implant to the auditory nerves– bypassing damaged or missing sensory cells in the ear–in a way that the brain can understand.

I am in awe of the inventors–Graeme Clark, Ingeborg Hochmair, and Blake Wilson–who are being recognized for their pioneering research leading to the development of Cochlear Implants.

Hopefully, soon we can do for sight, smell, taste, and touch what we can do for hearing and restore the impaired to fully functioning again.

We are living in a time of great miracles–thank you G-d!

Warrior Augmentation

Warrior Augmentation

I love the direction DARPA is going in with robotic exoskeletons for our warfighters.

Helping soldiers perform their jobs easier, more capably, and with less injury using human augmentation is good sense.

Military men and women often carry weight in excess of 100 pounds for long distances and perform other tasks that challenge human physical endurance.

Creating a durable “soft, lightweight under[or over]suit that would help reduce injuries and fatigue and improve soldiers ability to efficiently perform their missions” is an smart and achievable goal, and one that would give us great advantage in the battlefield.

The timeframe of 2012-2016 is an aggressive deadline to form the mix of core technologies, integrate them, and develop a wearable prototype.

I think the goal of having this be “potentially wearable by 90% of the U.S. Army population” is notable as not something that is for just special forces or unique missions, but rather something that can medically protect and make for a superior fighting force for all of our men and women.

This is really only the beginning of human augmentation with sensors, storage, processors, and robotics to make our warriors fight with the best that both man and machine has to offer. It’s not a fight of man versus machine, but of man and machine.

Seeing and hearing farther and with more clarity, connecting and communicating timely and under all conditions, processing loads of data into actionable information, fighting and performing mission with superior skills (strength, speed, dexterity, and endurance) and integrated weapon systems, guiding warriors to their targets and home safely–these are goals that man-machine augmentation can bring to reality.

And of course, the sheer medical and rehabilitative benefits of these technologies in caring for the sick and disabled in society is enough to “pedal to metal” drive these efforts alone.

Like on the prescient show from the 70’s, The Six Million Dollar Man, “We can rebuild him. We have the technology…Better than he was before. Better…stronger…faster.”

And I would add healthier and more deadly! 😉

Medical Hacks

Medical Hacks

Usually when we talk about the dangers of cyber attacks, we are concerned with the dangers of someone stealing, spying, or systematically corrupting our information systems.

But Barnaby Jack who died last week at age 35 brought us awareness of another, more personal and perhaps dangerous hack…that of hacking medical devices.

Barnaby, a director at computer security firm IOActive, became known first in 2010 for being able to hack at cash machine and have it dispense money.

In 2012, he drew attention to a flaw in insulin pumps whereby someone could cause it to administer a fatal dose to its unknowing victim.

This week, Barnaby was going to demonstrate how heart implants could be hacked, killing a man from 30 feet away.

With advances in the miniaturization and battery life of personal medical devices and implants for monitoring and managing patients health, more and more people could be exposed to malicious or murderous cyber attacks on their body.

With the potential for RFID embedded chips for managing our personal identities to bionics for replacing or enhancing human body parts with electronic and mechanical implants, the opportunity for someone seriously messing with our physical person grows each day.

If dangerous vulnerabilities are discovered and exploited in these devices, an enemy could go from the traditional attack on our information systems to potentially sickening, disabling, or even killing millions at the stroke of some keys.

Imagine people keeling over in the streets as if from a surprise attack by a superior alien race or the release of a deadly chemical weapon, only it’s not extraterrestrial or kinetic, but instead a malevolent cyber attack by a hostile nation or cyber terrorist group taking aim at us in a whole new and horrible way.

Those Are Some Prosthetics

Wow, prosthetics have come a long way–these are tough!

This video from Biodapt shows their high-performance Moto Knee being used in a variety of action sports including snowmobiling, motor biking, mountain biking, horseback riding, water skiing, snow boarding, and jet skiing.

Bloomberg BusinessWeek (11 July 2013) explains how the Moto Knee has hydraulic components that provide “tension and range of motion for intense physical activity.”

They cost around $6,000 and don’t replace the regular walking version, but Mike Schultz, the developer understands the need for these advanced prosthetics having lost a leg himself in a 2008 competitive snowmobiling accident.

I think it’s wonderful that these high-tech devices are being made available for disabled people to be able to do a wide range of exciting activities.

My hope is that as the technology continues to advance that we can have–like a person’s legs–one prosthetic device that is adaptive for use in every day use as well as more intense activities and sports.

It is hard to imagine people voluntarily trading their body parts for mechanical implants–but one day, in the not too distant future, these mechanical limbs will not only be a substitute for repair of real body parts, but will actually provide some superior capabilities–they will be used for body augmentation–and thus even be desirable by those who haven’t lost limbs.

What gives a leg up to prosthetics, as Hugh Herr in the Wall Street Journal (12 July 2013) put it is “that the designed parts of the body can improve in time, whereas the normal body, the biological body, degrades in time.”

With regenerative medicine and replacement parts by design, more than ever our physical bodies will be just the transient vessel that houses our heart, mind and soul–that which really makes us, us. 😉
