Abstract: An orthopedic measurement system is disclosed to measure leg alignment. The measurement system includes a tri-axial gyroscope configured to measure movement of a leg. The gyroscope is coupled to a tibia of the leg. For example, the gyroscope can be placed in an insert or tibial prosthetic component that couples to the tibia. The gyroscope is used to measure alignment relative to the mechanical axis of the leg. The leg alignment measurement is performed by putting the leg through a first leg movement and a second leg movement. The gyroscope outputs angular velocities on the axes the sensor is rotated about. The gyroscope is coupled to a computer that calculates the alignment of the leg relative to the mechanical axis from the gyroscope measurement data.

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 system and method is disclosed herein for measuring alignment of the muscular-skeletal system. The system comprises a sensored module that can be placed within a prosthetic component 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. Alignment relative to a mechanical axis is measured. In a two bone system with a joint therebetween the total alignment measured comprises offsets measured for each bone. The joint is placed in a predetermined flexion that supports measurement of the joint as it is moved. The joint pivots on a point that is along the mechanical axis. Points along the arc made by the joint rotating between a first and second point are measured. An arc maximum is determined. The arc maximum is then converted to varus or valgus offset relative to the mechanical axis.

Abstract: A sensor system uses positive closed-loop feedback to provide energy waves into a medium. The medium can be coupled to the muscular-skeletal system or be part of the muscular-skeletal system. A sensor comprises one or more transducers, an edge detect circuit or a reflecting surface. A parameter is applied to the medium and the parameter affects the medium. A transducer receives an energy wave that has traversed the medium and generates an energy wave signal. The edge-detect receiver receives the energy wave signal signal from the transducer and generates a pulse upon sensing a leading edge corresponding to a wave front of the energy wave. The edge-detect receiver comprises a preamplifier, a differentiator, a digital pulse circuit, and a deblank circuit. The transit time, phase, or frequency is measured of the propagating energy waves and correlated to the parameter being measured.
