摘要
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.
