Or can you be? Why would they not opt to use plastic?

Guess I wonder too if you are sensitive to things like microwaves or say...lightening! lol
My son is very sensitive to lightening. He feels it when it hits within a mile of him. He prefers to just stay indoors during thunderstorm, as it is very uncomfortable. Microwaves have not been mentioned, so they must not bother him.
That is very good to hear! Don't you wonder why they have to use metal? I mean there is some hard substances around not metal.
There are not many with the tensile strength of titanium though. Extremely strong and yet very hypo-allergenic. Some people are allergic to plastics also. I have a cousin that gets breakouts from plastics. That may be why.
The one I was shown was pretty much like the one above.
Those would be knee replacements Jackie. The ones in my sons leg are for the tibia and femur. He broke those and the titanium rods are inserted inside them. Those are the two weight bearing bones of the leg. He was 6'4" and weighed about 190 at 16.
I just wonder why a good grade of plastic wouldn't be better?
I'm not sure about that Jackie. Maybe it's due to how well the body accepts the material and durability, but they're making new discoveries all the time.
Plastics are not strong enough for some uses, such as legs. My sons are titanium, which is very strong. My husband has a Kevlar nose from Vietnam though, so they do use some plastics.
I knew about titanium, but not the kevlar. With the 3-D printing we may see some amazing stuff in time to come.
My mom got plastic knees and I saw them or samples and they were very strong and flexible.
Great; thank you, this is what I wanted to know. I guess you don't buss with the microwave either then? lol
Ah; well the way they always ask before they x-ray if you have any metal in you I always thought if you did it was bad news! lol
Perhaps it is simply so that they know what to expect from the outcome of the X-ray - or not to bother with that area. It may even be to recognize a certain sound the machine makes when it passes the metal.
Yes that was one of my thoughts too; glad you mentioned it. Hope someone answers that.
Yes; MRI is really what I had in mind. I do wonder too though about the knee surgeries; it seems most have gone to plastic (my mom had that) but they still put metal in some ppl. I just wonder why it isn't just one way; the best way.
