I love our government!

So I'm checking the latest-and-greatest government-endorsed performance standards for medical implants. In particular, I'm looking for their requirements for screws used in human bone.

Know how you determine the torsional yield strength and breaking angles? Graphically... Yes, graphically. Remember in middle school when you would plot lines on graph paper and determine their "solutions"? That's the same method you use to determine whether your device can be safely implanted into another human being.

That's gotta make you feel safe.

Plus I love the part where it says: "The simultaneous use of two chart recorders may simplify the ability to measure torsional yield strength..."

So here's a quick test: Who here (other than DB) is old enough to have ever even seen a strip chart recorder???

This would be funny if it didn't involve humans.

Good times!

IAW teh ASTM F543 - 07e1

Considering the limitations on your intellectual capacity, yes. Yes it is about my hair. Don't try to think much deeper into it either -- you'll just give yourself a headache.

That's the one!

Dig those circa 1960-1970 drawings. Doesn't it make you want to have orthopedic surgery?

Sure.

Long as Barrycare is in place!

Hell when that thing was written, it was all done with brash bushings. O-rings would be part of that "new-fangled" plastic stuff.

I don't like Barry at all, but the piece of regulatory cluelessness predates Barry, GW, Clinton, Bush I and even Reagan. I'm guessing this is Nixon-era (or before) regulatory work.

I think I'm going to round up a vintage strip chart recorder:

and do the calculations with a cylindrical slide rule:

And put the whole thing in our design master file.

Do you want to know what I use such apparatus for?

My next orthopaedic surgery will be in plunkeys garage utilizing the 5-Axis processor for mazimum safety and results.

Hell no!
