Hi

I'm a student product design engineer studying in Glasgow. For my fourth year project I have been researching Bone saws and plan to design one over the coming 7-8 months.

During a meeting with a consultant orthopaedic surgeon in the a local hospital I was told that there is often a problem with the bone burning and causing thermal injury during use of a power bone saw. For this reason he preferred to use a hand saw to cut through the bone.

I was wondering if this was a universal problem experienced by many surgeons or the view of just one man?

Please reply to this as any information from those who use these products will be invaluable to me.

Thank You

During the three months of ortho that I've done this year (all at major academic centers in the US), I?ve never heard of this. Sometimes we would squirt a bit of saline in there while we were sawing, but I don't think thermal injury was a major concern. In fact, I've never used a hand saw before. Every one that I've worked with has used the power saw for joint replacements, amputations, and all other cases where sawing was required. Might be different at some places though.

Yes, it can be a problem...and not just saws but any device with high rotational speed can cause thermal injury. This is one of the main reasons we irrigate the area inbetween rotations/sawing: to drop the elevated temp.

In continuation of my previous posting i was wondering on ways that orthopaedic saws could be improved.

I am assuming that the irrigation of the area between the blade and the bone is done by some liquid, (is it saline?).
How is this usually applied?
Would it be easier if it was in-built so that the power saw applied it to the blade area itself, allowing the surgeon/nurse to not have to apply it?
Does anyone know of any products on the market that do this?

Any replies to this would be much appreciated or e-mail me direct on nickmathers38@hotmail.com.

Cheers
