The invention comprises a system for securing an implant to a bone comprising an implant which is affixed to the bone, a grout or bone cement comprising a composition that cures in an exothermic reaction and which is capable of securing the implant to the bone in a cured state, a device which provides access to the grout or bone cement in position on the bone and a tester which measures temperature over time to detect the exothermic reaction so as to determine when the composition reaches cure. The tester comprises a sensor joined to a circuit and to an indicator that emits a signal in response to a current emitted to the circuit by the sensor.

A surgical sensor system for collecting internal patient data comprises a sensor module comprising a housing and a sensor disposed within the housing, and an attachment device comprising a socket for receiving the housing and an exterior anchor feature for attaching the attachment device to biological matter. A method of implanting a sensor module for use with an orthopedic implant device comprises making an insertion portal in anatomy of a patient, positioning a sensor module in the anatomy in a first position relative to the insertion portal, and positioning an orthopedic implant in the anatomy in a second position relative to the insertion portal such that the orthopedic implant is separate from the sensor module.

The invention comprises a system which determines the cure status of bone cement which is then used in making surgical decisions on the cement use and further comprises a system for aiding in securing an implant to a bone using a cured grout or bone cement. The system includes a device which comprises a frequency sensor joined to a circuit to monitor one or more frequency signals, and to an indicator that emits a signal in response to a current emitted to the circuit by the system while monitoring the state of cure. The invention also relates to surgical methods using the system.
