Ortho/Trauma implant and metalwork discussion

[skylung]

Hello, I qualified 9 months ago and started to work in orthopaedic trauma theatres for a trauma center in th UK. I would like to think I have come a long way in terms of my knowldege on implants and metalwork but there are days where looking at optechs is not enough especially in hips where heads and cups can come in various combinations. Ours is a teaching hospital so sometimes the surgeons will quiz us on how well we know the implants and sometimes i just stare back, like a paralyzed owl. Hahaha

So i am starting this thread in hopes that this will be a sharing ground between us. Any info under the sun is welcome may it be strategies, tips, mnemonics etc as long as it is about orthopedic metalwork. I'll make a post as soon as I can organize my ideas haha. BTW, if we are a house in game of thrones, i think our banner would say "steel and bones".. Dunno bout our sygil though

We always have reps available for total joints. Our doctors use numerous different companies and styles of implants...there's not way I could ever keep them straight! I mean, I know for example that they need the different parts of a certain joint, but as far as which ones are or are not compatible, I'd be in trouble.

As far as hips go, the general rule i have in my mind is if it is an uncemented cup, the last reaming size will directly translate to the size of the actual cup to be used. If it is cemented, it is important that the actual cup is one size down from the last ream. In terms of material, im still unsure which ones are not compatible between plastics ceramics and metal.

in cementing, the general rule is AFAIK, the max time to mix is 45secs regardless of the setting time of the cement.

I wonder if anyone here is knowledgable on the stryker hip system like the alumina, v40, etc
