In the end, I think bone will be the "new bone." As awesome as cyborgs sound, we've yet to get to the point that our artificial replacement parts do better than a healthy version of the desired organ.
Bone itself tends to adapt to implants, so sometimes, implanting bone-replacement materials that are stronger/stiffer/less breakable than bone can cause problems in surrounding bones or joints.
"Coming up next on 'This Old Hip Replacement', we get to work on a new Femur for this 1953 Rancher. Now, the original was primarily made of Calcium, and we could go with a Titanium replacement, but we want to maintain the rustic structure and feel. And if you're anything like us, that means working with wood. Personally, I prefer Red Oak, but the Rattan or Sipo both work just as well."

It takes some creative reading to say that this material "handles natural impact better". Personally, I didn't see that claim in the article, and would not believe it if I did (I am working on my second degree in the field of biomaterials research at the moment).
While their claims of better oseointegration seem reasonable (I would have to see their actual experiments to be sure) I can't help but have some doubts over this gem:
'"When implanted into the body, it is encapsulated by fibrous tissue. But if you introduce pores into the titanium. the mechanical properties can be compromised." If the titanium is weakened, it may break, leading to further damage to the bone.'
There are a number of production and surgical techniques to limit fibrous encapsulation of a Ti implant. Suggesting that porous charcoal will not have the same strength drops as porous Ti is very misleading; introducing voids into any material will cause a drop in strength.
Still, these could be points of bad reporting, not bad science. It is an interesting research direction in the field.
@kyre: In case anyone is interested, I turned up this paper (from the author in question, not sure if it is the article in question): [www.rsc.org]
The Discovery article is misleading, if this is what they reference. They are talking about using wood to make hydroxyapatite(HA), a very commonly accepted bone material. The important point is the type of porosity they managed to create by using wood as their starting material.
There is brief mention of HA, but it should be a bit more apparent, the bone substitute in the final product bears no resemblance to wood besides the internal microstructure.
Will they make the screws out of wood as well? Is it pressure treated for internal parasites? Will I have to give up my Ti ring in place of something from Lumber Liquidators?
And finally, if BlLam has his Ti rod replaced with this, does that mean he will have a part wooden leg, and be more pirate than ninja? Although, "Blam Beard" does have a nice ring to it.
@Curves: B&B have many fond memories for me. I remember watching the series finale with this cute girl from my Psych class named Danielle. I'm pretty sure she's in therapy from that night.
@GitEmSteveDave_HasAList: I never, ever go to first day movie releases, but I did for B&B Do America, a matinee no less. I was the only one in the theater over 16 years old and had so much fun that I saw it twice.
Interesting. And only 99¢. Still, having just read John Mahoney's incredible Giz article, Wy We Need Audiophiles, I'm now a true-believer and will wait for this app to be released in a $10,000 audiophile version. I'm sure I'll hear a difference in my iPhone's output.
@bosskev: the article actually inspired me to only eat rice krispies. for the snap, crackle, and pop. i now need to find a place that sells it for $5,300 a box.
It wont be long till someone hacks it and then everyone will have the perfect body again. (Thank goodness, I was afraid I was going to have to do a sit up or something.....)

Should be easier to get through airport security.
