New 3D project (only marginally related to HDTs)

Recommended Posts

Marginally related only that it will allow me again to climb into one.

 

I’m in a celebratory mood, brought upon by a change in venue. The trio of physicians, who have been ministering to this old carcass I’ve been carrying around for 74 years, came to a conclusion that the condition that postponed the February surgery has been sufficiently beaten down to try again on April 19th. Whenever I’m in celebratory mood I feel a need for literary output in the language of William Shakespeare and Ernest Hemmingway which I learned in my late youth. So here it goes.

 

I always thought that doctors were like engineers. Obstetricians are like manufacturing engineers making sure the “product” leaves the “factory” on time and meets the essential quality standards. Primary doctors are like product engineers keeping track of the product in use and in the field, informing the clients on the latest tweaks, pointing out things that could cause the product to fail because of misuse or abuse. Emergency room doctors are like service engineers sent out to make the product work again after abuse and failure. Surgeons are like the “super techs” usually involved when everything else fails and without their help the product will have to be junked. The equivalent of the design engineers would be the transplant guys, microsurgery guys, drug designers etc.

 

When I see 3D, I know that the essential work and repairs on the product at hand will be done well, accurately and with forethought. The subject at hand is a pair of diseased knees which reduced their owner to resort to an alternate form of locomotion instead of walking.

As some of you may know the owner of the aforementioned diseased clunkers is big into 3D,

and when he saw this

 

Screen%2BShot%2B03-24-16%2Bat%2B09.57%2B

 

he knew that he was in good hands. Why, because the trial and error, fitting and futzing, etc., would be done virtually and on a computer screen and not on the said diseased pair while their owner was in a la la land and in the hands of “another engineer”, this one capable of cranking over and re-starting products that lay dormant for a while.

 

So why am I so excited? The following is a perfect symbiotic example of medicine and engineering in perfect harmony.

First yours truly was subjected to an MRI-like x-rays from hips to toes, that info was sent to Massachusetts to create a 3D model of the existing skeletal model from hip to toes. Why hip to toes? The plan is not only to install new knees but to also realign things away from the old bowlegged cowboy look to the more youthful and straighter self. Once those parameters are set the computer goes to work again.

 

Screen%2BShot%2B03-24-16%2Bat%2B09.58%2B

 

It figures out how much stuff has gone missing and needs to be added to achieve straightness and full J curve motion from straight knee to bent knee (0 to 90 degrees). Current techniques only take into considerations those two extremes and one in five patients is not too happy with what happens in between those angles.

The computer then figures out the shape and size of the actual implant for each side.

 

Screen%2BShot%2B03-24-16%2Bat%2B09.59%2BScreen%2BShot%2B03-24-16%2Bat%2B09.36%2B

 

The next step is truly revolutionary and pure engineering. The computer is connected to a 3D printer to manufacture plastic templates to be used in surgery to precisely cut, bore and shape the bone to accommodate the new prosthesis.

 

Screen%2BShot%2B03-24-16%2Bat%2B08.08%2B

 

 

Once the bones are exposed the templates are placed in succession to drill (through holes) or cut (through slots) to shape the bone for the implant.

 

Screen%2BShot%2B03-24-16%2Bat%2B09.41%2B

 

Screen%2BShot%2B03-24-16%2Bat%2B09.39%2BScreen%2BShot%2B03-24-16%2Bat%2B09.40%2B

 

Screen%2BShot%2B03-24-16%2Bat%2B09.40%2BScreen%2BShot%2B03-24-16%2Bat%2B09.41%2B

 

Screen%2BShot%2B03-24-16%2Bat%2B10.01%2BScreen%2BShot%2B03-24-16%2Bat%2B10.02%2B

 

Once all that is done the surgeon reaches into the same kit to retrieve a pair of beautiful and new “spare parts”. Let the making of the new Borg begin.

 

Screen%2BShot%2B03-24-16%2Bat%2B09.44%2B

 

All kits are patient specific, clearly identified (the 3D printer makes kits for several patients on each run) and come pre-sterilized to the surgeon.

At the orthopedic doc recently with my wrist mishap, I saw the product models of this. Played with it for awhile waiting on the doc. They had the whole kit sitting in the exam room for demo purposes. According to this doc, hips, elbows, some shoulder joint parts, are all becoming available as well. Another avenue he mentioned was partial vertebrae replacement and disc replacement as well.

The 10 years of war in the middle east has pushed reconstruction surgery to new heights, with the general public getting the benefit of the advances.

The company is a medical startup in Bedford, Mass (they just went public), has been around for 8 years and this procedure and their kits have been in use for 4-5 years. The surgeon who will be working on me teaches other doctors how to perform the surgery. Warned me there might be others in the operating room.

Wait a minute; I don't see any Huck bolts.

 

Good luck with the joint jockeys.

Luckily, they stopped using Huck Bolts, just in time!

 

You will have an easy time of it, and it really will go by fast!! The drugs even help on that end also.

 

They ended up only having to do a partial replacement (resurfacing is actually what they do) instead of a TKR. I could have sworn it was going to be a Total based on how much pain I was in versus the surgery 10 years ago.

 

But no, when he opened it up, a partial was all that was required! Happy Camper here! Recovery is going to be short. Stopped using the walker during the 1st PT at the hospital, and stopped using the cane during the 1st outpatient PT.

 

I did find a few useful videos to know exactly what they were going to do to me before the surgery this time. 10 years ago, I believe they rated them ADULT ONLY, and the quality was on par with some of the early Adult Only films (so I've been told).

 

Or maybe you want to wait until it's all over to look and see how they did it?

 

I'm sure you're in good hands and will be looking for a great report after it's all done.

 

The super good news is that you will be able to play the piano after it's all done! I'm not able to, but of course I didn't play it before!

Phoenix,

That technology is truly amazing and I thank you for sharing all the images. Best of luck with the procedure and subsequent PT.

Rocky, I found a youtube video of this whole procedure (about and hour), which I opted not to watch. Of course, the DW, who is a veteran of ORs (including some of the first transplants ever performed) got right into it. "Reported" to me that it was "neat" and impressed with all the new instruments that did not exist in "her times".

We mentioned to my surgeon that we saw the video, he questioned me "why did i want to watch it". He seemed to be relieved that it wasn't me and only my RN wife.

Henry.......

 

I am a bit worried about your "NEW parts" Replacement.......

 

Look as hard as I can I can NOT see any zerk fitting and you sure don't want any of those "pre-lubed" joints with the high overloads that you encounter when you are running at Max-Geezer-Warp-7.634 Speed"...........

 

When you get the zerks installed I would suppose some of the "Food-Grade" Lubriplate might be nice but they also make "specialty-lubes" for "classic rigs" with SAE W250 being a big seller.......

 

If "Grumps" were still lurking around he might be one of those "other-folks" in the operating room.......he'd be the Geezer with the grease gun and a clean shop rag the clean the zerk before shooting the Lubriplate until it came out the..........seals??.....or......grease drain hole??

 

Remember Henry those regular knees are for "regular-duty-cycle-Geezers" you know like golfers, bass fishermen, casino-creeps, etc.......you see Henry your going to have to have the "Xtreeeem-duty" joints just to keep up with the "hitch-demand".........

 

Drive on..........(don't let your joints......skweeek)

Henry, If you find out where they put the zerk fittings I'd like to know. had both of my knees x-rayed last week and he told me not yet but it isn't far off. S I figure if I can get some grease to em maybe I can put the knife off untill they can do it all by CNC and maybe it will be cheaper because the more you do the cheaper it gets. Right? Any Way Take Care and God Bless. Pat

Pat, all kidding aside, they do have a "zerk fitting like" solution for knees to avoid surgery, Check this out http://www.synviscone.com/what-is-synvisc-one/synvisc-faqs.aspx My surgeon was pretty blunt that my suckers have no cartilage left, (one has some left) and are essentially bone on bone. They did try cortisone injection in both knees and the relief lasted about three weeks. I wasn't too keen on synviscone, it has some side effects, it has to be repeated every few months and I wondered what happens if this crap decides to leave the knees and start traveling to other corners of the body.

It's not uncommon for surgeons to feel that you are "too young" for the surgery. That's a legacy of the older types of prosthesis from years back and the surgical methods used then which on knees had a ceiling of about 10 years, or so. My surgeon tells me that Conformis knees could last upwards of 25 years. But as anything he qualifies that with all the other factors, activities level, general health any other chronic problems, etc.

 

Dolly, there will be a hiatus in hitch production after the 19th and bunch of them will leaving the premises before. I expect the nickel-chromium (or titanium, don't know which yet) and polyethylene parts to be functioning well and be fully engaged in hitch ministering soon. What's the sense of becoming a Borg if that doesn't contribute to the well being of the "collective", DW already carries spare parts.

Really cool Henry, thanks for sharing. The DW is after me to get an overhaul. I have a bad shoulder, 2 knees and one bad hip.

I have a hell of a pain tolerance (I pass kidney stones without drugs), but these knees had me few times at 10 on scale of 1-10, almost called 911. So I'll be gauging the surgical procedure and recovery of a that scale. I'll let you know.

I had a bad reaction to Synviscon. The right knee did ok thru the 3 injections and seemed to be better for 3-4 months. The left knee however blew up like a balloon within 3-4 hours and would bear no weight. Took 2- 14 day Prednisone dose packs and 2 week on crutches to get it back under control.

My current schedule to join the Borg collective is June 14th.

That is for the first limb. Second limb 3 days later. But that still depends if the three physicians are indeed plugged into the hive consciousness together, in the next two weeks. It has been a problem.

Read the fine print on the warranty. Make sure it's unlimited mileage, parts and labor! (I hear the shop rate isn't cheap.)

 

Hope it goes smoother than that ET install at the ECR last year! 5/16" air line....

Best wishes. Make sure everyone does hand washing every time they enter your room. Make sure you are ready for the second one and don't push it if you are not. Many people want them both done at the same time or very close together but I have yet to hear from someone who would do it again.
