Whirling simulator
It may not look like a human hip, but it is doing the work of one - giving 'speed walking' a whole new meaning.
We're simulating a year's worth of walking in about, in about three days, three and a half days, we can do a year's walking.
Inside the container is a hip replacement part. It swirls around in fluid similar to what's in the body. While the simulator does its thing, A computer gathers data on the wear and tear of the joint.
The company we're working with now is testing this new material. They think it's better than what's available.
That company, 'Advanced Bio Implants', hopes the new material will last longer.
We're evaluating our materials. We are finding out what types of properties they need to have, and we're doing it in a systematic fashion now. That's going to help us get to that ultimate goal of a material that could last 30 to 40 years.
This simulation lab belongs to suburban Detroit's Beaumont (BO-mont) Hospital. It's one of the few test sites housed inside a medical center.
Working at a hospital setting actually gives us an unbiased, independent feedback.
It's also a good resource for surgeons on staff who do hip replacements - or 're'do them when they wear out.
When we have to redo those parts, we can bring those old parts to the lab and they can test them here, determine why they failed, how did they fail and use that information to determine how can we make new parts that can last longer and not fail in those same methods.
Stepping up the research to make hip replacements more durable. For WebMD, I'm Damon Meharg.
