Muscular-Skeletal Joint Stability Detection And Method Therefor
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 impla...

| description | 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. |
