    Abstract: A sensing assemblage for capturing a transit time, phase, or frequency of energy waves propagating through a medium is disclosed to measure a parameter of the muscular-skeletal system. The sensing assemblage comprises a transducer and a waveguide. The transducer is coupled to the waveguide at a first location. A reflective surface can be coupled to the waveguide at a second location. The reflective surface is configured to reflect energy waves away from the reflective surface. An interface material that is transmissive to acoustic energy waves can be placed between the transducer and a waveguide to improve transfer.

    Abstract: A knee bone cut system and method is disclosed. The knee bone cut system supports cutting an anterior portion of a distal end of a femur. The system comprises a sensored insert, a femoral rotation guide, and a remote system to receive and display sensor data. The sensored insert provide data related to load magnitude, position of load, and leg position. The femoral rotation guide has moveable condyles to adjust condyle position in a rapid manner. A pinch mechanism and lock mechanism respectively move the condyles into contact with the sensored insert. Moreover, the femoral rotation guide can be loaded similar to a final installed insert over a range of motion. For example, the patella can be placed on the femoral rotation guide allowing the patella to load the sensored insert. The femoral insert guide includes guide holes that are used in conjunction with a bone cutting jig.

    Abstract: A measurement system for measuring a parameter of the muscular-skeletal system is disclosed. The measurement system comprises a capacitor, a signal generator, a digital counter, counter register, a digital clock, a digital timer, and a data register. The sensor of the measurement system is the capacitor. The measurement system generates a repeating signal having a measurement cycle that corresponds to the capacitance of the capacitor. The capacitor comprises more than one capacitor mechanically in series. Electrically, the capacitor comprises more than one capacitor in parallel. In one embodiment, the capacitor includes a dielectric layer comprising polyimide. A force, pressure, or load is applied to the capacitor that elastically compresses the device. The capacitor is shielded from parasitic coupling and parasitic capacitance.

    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.

    Abstract: A measurement device suitable to measure a load applied by the muscular-skeletal system is disclosed. The measurement device can be a prosthetic component having an articular surface for measuring parameters of a joint in extension or flexion. A first and second support structure forms an enclosure having load-bearing surfaces. The first support structure includes at least one alignment feature extending from a surface. The second support structure includes a corresponding opening for receiving the alignment feature. The first and second support structures include a peripheral channel and corresponding flange to support sealing of the enclosure. Interior to the enclosure is the measurement system. The alignment feature couples through and aligns a first load plate, a sensor array, and a second load plate to surfaces of the first and second support structures. The sensor array is coupled to electronic circuitry in the enclosure via a unitary circuit board.

    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.
