Aircraft technology helps diagnose artificial hip, knee problems

To assess the wear and tear on jet engine parts, mechanics used an old technology called ferrography to run the aircraft’s lubricating fluid through a magnetic device to separate out metal shavings and other ferrous engine debris. A University of Rhode Island researcher uses a similar process to assess the wear and tear on artificial hip and knee joints so patients can reduce the number of follow-up surgeries they must undergo or reduce the time spent in revision surgery.

Surgeons put themselves at risk, despite evidence

Exposure to blood and body fluids while operating places surgeons at risk, yet a large number of doctors continue to put themselves in danger despite knowing the evidence, according to a University of Alberta study. Double gloving is a safety measure, which decreases the risk of exposure. However, many surgeons do not incorporate this precaution into their personal practice. This study, which is published in the current edition of the American Journal of Surgery evaluates surgeons’ gloving practices and hepatitis status.
