    Purpose of the Study:

    • To introduce a new, high-fidelity miniature transducer for direct intraosseous pressure measurement.
    • To evaluate the transducer's suitability for dynamic pressure studies.
    • To explore its potential application in diagnosing bone diseases.

    Main Methods:

    • Development of a miniature, high-performance pressure transducer.
    • Direct insertion of the transducer into the intraosseous space.
    • Utilizing the transducer for dynamic intraosseous pressure measurements during gait.

    Main Results:

    • The transducer is easy to assemble and insert.
    • It successfully captures dynamic intraosseous pressure variations.
    • Demonstrates feasibility for detecting pressure changes associated with bone pathologies.

    Conclusions:

    • The miniature transducer offers a promising new tool for intraosseous pressure assessment.
    • It facilitates dynamic studies, crucial for understanding bone biomechanics.
    • Potential diagnostic applications in osteoarthritis and osteonecrosis are highlighted.
