Print Yourself a Femur

Scrooge919 writes "Newscientist is running an article about a new 'bone printer' that can be used to replace segments of broken bones. A large segment could be fabricated in about an hour and would be able to support the person's weight. Over the course of about 18 months, the section is absorbed by the body and replaced with real bone."

      As someone with about 6-7 years (I hope) left in my current hip replacement and with the possibility of facing (hopefully) 3-4 more (1 per 10-15 years; based on todays technology and my activity level) I also can wait.

      But unfortunately the article does not talk about the possibility of replacing joints or large parts of missing bone (ie. the top of my femur and the part of my socket that was grinded out). Hopefully this technology will progress to the point of providing full joint replacements by the time I am due for my third replacement.

      Full joint replacement will be a huge benefit to many of us as we grow older and for those that are not as lucky as I am and can not simply get a replacement but instead face the choice of fusion instead.

      I understand from the article how they can use it to replace shattered or destroyed sections but I am not sure that a) whole bones, or b) extensions to existing bones (post joint replacement or trauma) is possible with this procedure. So maybe "Print Yourself a Femur" is going a little far but I hope not.

      Without reading the article I can tell you that this "printed bone" can't be used to replace joints.

      The technology is producing a bone matrix replacement, which is nauturally transformed into bone by the body. (due to the nature of the way bone is contsantly being broken down and rebuilt.) The problem is that joint tissue is a whole other ball game. You need cartilage, and a nice joint sinovioum, and neither of these will just form being using a matrix.
      This mostly for better union of broken bones.

    Here is an example use of this technology. The piece needed was to strengthen the jawbone of an elderly lady. We actually printed it out (plastic, not bone, but you get the idea), and it was shown to fit quite nicely during an operation.

    The problem? FDA won't let the doctors leave it in there. They just got to put it in place and take a few pics before removing it again. So the woman still has a weakened jawbone, despite the fact that the technology exists to help her.

      Well, I think these guys can probably help.

      I recommend getting two; lemur production doesn't work so well with only one lemur machine. Make sure they are compatible; there are two types and you need one of each.

      By the way, it's quite likely that local laws will prevent you from owning a lemur-producing machine. Many types of lemur-producing machines are very rare and once they break, they can't be fixed, so if they all break that's it for lemur-machines. As a result many governments are quite protective of them.

      Also, operation of the lemur machines in such a manner that they will actually produce lemurs and not just consume resources may be very, very tricky; I'm not certain but I do know a lot of other, similar machines often take many skilled experts to cause to produce.

      Anyhow, they're not as user-friendly as you'd like and you can't just pick them up at Best Buy, but you can probably get some lemur machines if you really put your mind to it. Best part of all is there are billions of years behind their development, so they are pretty sophisticated.

    Somehow, in 37 years out of the 227 years this country has existed, the nation now thinks that medical advances can only exist after a lengthy approval process, complete with beurocratic red tape, medicare approval, and gov overhead.

      Doesn't that beg the question: How do you tell the "life-altering discoveries that work" from those that don't?

      The only way to be sure, is to test them and have someone stand over them to make sure that the tests are done in a reasonable manner. No amount infomercial airtime, anecdotal testimonials nor authoritative claims by actors dressed up in white lab coats, will answer that question. Just ask those people who drank radium laced water, becuase they were told it would cure their diseases and make them healthy and vigorous. Oh wait! You can't! They died horrible deaths from it's toxic effects. Quite a life-altering discovery for them, wasn't it?

      I doubt this would work well with teeth, since by design the "printed" bones are only temporary, intended to be replaced by real, growing bone. Teeth don't grow like other types of bones, so this would most likely not work.

Why wasn't it allowed in the US, because no studies had been performed which measured its affect on the pregnancy. Thank you FDA!

    Thanks, Eric. I had to deal with someone close to me who was essentially addicted to ephedrine through daily use of "Mah Huang" aka ephedra sinica, a natural herbal supplement, the active ingredient of which is ephedrine -- which is no less harmful than crank. It can be just as deadly, too -- an overdose can be fatal. Way, Way bad!

    pseudephedrine is the manufactured ingredient, the main ingredient in Sudafed, a leading decongestant. The same people that wouldn't take a handful of Sudafed will go ahead and take the equivalent dose of mah huang, because it's natural and organic. So is deadly nightshade. Not a great idea.

    While it would be a shame if every herbal tea company were regulated into oblivion, its also clear that some "natural organics" can be quite dangerous (tobacco, psilocybin mushrooms, peyote buttons...)-- not to mention all kinds of unnatural inorganic treatments people try. Prior to the founding of the FDA there were some truly dangerous quack treatments -- electrical shocks to the nads for STD's for example. Unscientific, dangerous and quite scary stuff!

    Uh, ephedrine is much weaker than methamphetamine. That's why people go through the trouble of making meth - often using ephedrine as a base. (Which is a large part of the reason the Drug Warriors get so bent out of shape about ephedrine.)

    Exactly. Taking a little Mah Huang tea or a little Sudafed to clear your sinuses is generally safe. I prefer the tea, since you're also getting soothing warm liquids and herbs usually contain secondary substances that help balance out the action; I also find the use of herbs more aesthetically appealing.

    Taking large doses of either to get "high", or taking it constantly as a weight loss drug, is stupid. But it's your body and none of the government's business.

    some "natural organics" can be quite dangerous (tobacco, psilocybin mushrooms, peyote buttons...)

    Psilocybin is quite safe, it's estimated that it would take several pounds of mushrooms to cause an overdose. Peyote is pretty safe, though I did read one account of a fatality from vomiting-related bleeding in an alcoholic man. (By "safety", I refer to the pharmacological actions of the drugs. Taking a psychdelic drug can result in a very intense experience, for which one should be psychologically prepared - treat all drugs, from chocolate to morphine, with respect. And don't do stupid things like drive while under the influence of any drug.)
