A new method to measure intraosseous pressures.

A new technique for measuring intraosseous pressures involves inserting a miniature transducer directly into the intraosseous space. A high-performance, high-fidelity pressure transducer is easy to assemble and insert. The transducer permits dynamic studies of intraosseous pressure during gait, and constitutes a promising tool for detecting changes in intraosseous pressure in osteoarthritis and osteonecrosis.
