    Abstract: An orthopedic implant having a three-axis accelerometer is disclosed. The three-axis accelerometer is used to detect micro-motion in the implant. The micro-motion can be due to loosening of the implant. The implant is configured to couple to the muscular-skeletal system. In one embodiment, the implant is configured to couple to bone. An impact force is imparted to the bone or implant. The impact force can be provided via a transducer coupled to the implant. In the example, the impact force is imparted along a single axis. The three-axis accelerometer measures the impact force along each axis. Resultant peaks of the quantitative measurement and the frequencies at which they occur are measured. The peaks and frequencies of the measurements correspond to micro-motion. Typically, the frequency of interest is less than 1 KHz to determine if micro-motion is occurring.

    Abstract: An orthopedic system to monitor a parameter related to the muscular-skeletal system is disclosed. The orthopedic system includes electronic circuitry, a sensor, and a remote system to monitor and measure. The sensor is configured to measure color or turbidity. The electronic circuitry is coupled to and interfaces with the sensor. The electronic circuit includes a transmitter to transmit measurement data from the sensor to the remote system. The orthopedic system is configured to monitor color or turbidity of a fluid in proximity to the muscular-skeletal system. The orthopedic system can transmit a signal when a predetermined color is detected or when the turbidity of the fluid exceeds a predetermined value. Alternatively, the remote system includes a processor and software configured to analyze the measurement data from the sensor and transmit a signal when a predetermined color is detected or when the turbidity of the fluid exceeds a predetermined value.

    Abstract: A system is disclosed herein for providing a kinetic assessment and preparation of a prosthetic joint comprising one or more prosthetic components. The system comprises a prosthetic component including sensors and circuitry configured to measure load, position of load, and joint alignment. The system further includes a remote system for receiving, processing, and displaying quantitative measurements from the sensors. The kinetic assessment measures joint alignment under loading that will be similar to that of a final joint installation. The kinetic assessment can use trial or permanent prosthetic components. Furthermore, adjustments can be made to the applied load magnitude, position of load, and joint alignment by various means to fine-tune an installation. The kinetic assessment increases both performance and reliability of the installed joint by reducing error that is introduced by elements that load or modify the joint dynamics not taken into account by prior assessment methods.
