An expandable implant for treating bone preferably in a minimally invasive manner includes a preferably cylindrical core element extending along a longitudinal axis and preferably a plurality of nestable, expandable sleeves extending along a longitudinal axis for placement radially about the core element. The plurality of nestable sleeves are sequentially insertable over the core element in such a manner that a first nestable sleeve is inserted over the core element and each subsequently inserted nestable sleeve is received between the core element and the previously inserted nestable sleeve such that the insertion of each additional sleeve causes each previously inserted sleeve to outwardly expand.

Nested expandable sleeve implant

A monitoring system includes: (1) an implant having at least one sensor and configured for at least partial insertion into a patient, a first one of sensors being in contact with a perimeter of a hole in a body portion of the implant for accepting a fastener; (2) a microchip associated with the implant and the sensor, the microchip configured to receive at least a first signal from the sensor; (3) a transmitter associated with the microchip for transmitting a second signal, representative of the first signal; (4) a receiver located outside of the patient, the receiver configured receive the transmitted second signal; and (5) a display device associated with the receiver, the display device configured to provide an audible or visual representation of the second signal to a user.
