Abstract:
An apparatus for preventing osteopenia, promoting bone tissue growth, ingrowth, and healing of bone tissue includes at least one rigid plate (11, 12, 31, 40, 42, 47, 50, 53, 70, 71) to support the living body, a stiffly compliant structure (13, 14, 41, 48, 48', 51, 76) engaged to the at least one plate, a dynamic force transducer (15, 15', 38, 38', 44, 44', 54, 77) engaged to the plate to vertically drive the plate. The stiffly compliant structure having a spring constant such that, in the context of the total of the mass of the plate and the mass of the plated-supported body mass, the total mass and the compliant structure exhibit a naturally resonant frequency in the range of 10 Hz to 100 Hz.

Abstract:
A method and apparatus for preventing osteopenia, promoting bone tissue growth, ingrowth, and healing of bone tissue includes the step of and means for applying a mechanical load to the bone tissue at a relatively low level on the order of between about 50 and about 500 microstrain, peak-to-peak, and at a relatively high frequency in the range from about 10 and about 100 Hz. Mechanical loading at such strain levels and such frequencies has been found to prevent bone loss and enhance new bone formation.
