Implant-derived metals found in cerebrospinal fluid

If going for an implant, remember this:

“No increase in cerebrospinal fluid metal levels was observed in patients with implants lacking cobalt-chromium-molybdenum components.”

I would find out the materials used to specifically make the wear surfaces. There are alternative now available. Zirconium is one.

Great.

they say that by the time you die, you have enough plastic in your brain to make a spork. We are all going to die of something - nobody gets out alive.

I always heard it as I like smoking lightning.

I’d imagine from tooth implants and whatnot as well?

"I’m screwed."

My too. Maybe my titanium hips will eventually kill me, but they will have been well worth the many years of quality life they've given me.

My hips were "installed" nine years ago. A few months ago I went in for a check-up, and the x-rays showed zero wear over all that time. Those things are truly a modern miracle.

I’m 74 - new knee 2 years ago.
miserable operation and rehab but 100% would do it again.

My first fake hip in 1985 was molybdenum, which is mentioned in the article. It was replaced in 2005. Other hip was replaced in 2020. Both current hips have titanium — and probably some other stuff. Cadaver, too, I’m told.

Definitely quality of life is the big thing. Not being able to walk for the last 40 years — can’t even imagine.

Spouse has 50 year old metal in one hip and 45 year in the other. Will be 98yo
next month and has no dementia, just usual slowing down walking with cane or walker

Thanks for this; my wife had one knee replacement surgery about 7 years ago. She needs the other replaced later this year. I’ll remember to ask the surgeon about the composition of the replacement, and if alternatives are available.

For whatever it’s worth- one of my uncles had a hip replacement surgery in his 80s. He recovered, went to therapy, drove a car well into his 90s, his mind was sharp until ha was almost 100, and he started having cognitive issues.

He was wounded at Guadalcanal in WWII, recovered, came home and had a successful life, raised a family, and live to 102. Now THAT was one tough guy!

The only thing….he was a strong democrat all the way to the end.

“THAT was one tough guy!”

That generation ... pretty impressive!

The day after Mom’s 98th birthday, she broke her hip and they did a replacement. Surprised me that they’d do it considering her age, but her heart was strong and she was spunky. She did fine, too. But she died last April 15, three months before 100th.

You are blessed to have had her so long. My Mom passed in ‘86 from stroke related complications. She was in her early sixties.
