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: 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: 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 distractor suitable for measuring a force, pressure, or load applied by the muscular-skeletal system is disclosed. An insert couples to the distractor. The insert has at least one articular surface allowing movement of the muscular-skeletal system when the distractor is inserted thereto. The insert can be a passive insert having no measurement devices. A sensor array and electronics are housed within the distractor. The distractor can dynamically distract the muscular-skeletal system. A handle of the distractor can be rotated to increase or decrease the spacing between support structures. The measurement system comprises a sensor array and electronic circuitry. In one embodiment, the electronic circuitry is coupled to the sensor array by a unitary circuit board or substrate. The sensors can be integrated into the unitary circuit board. For example, the sensors can comprise elastically compressible capacitors or piezo-resistive devices. The distractor wirelessly couples to a remote system for providing position and magnitude measurement data of the force, pressure, or load being measured.

Abstract: A medical device used for measuring loads at joints. The device may have a stem coupled to bone, a neck, and a ball joint coupled to the neck. The ball joint may be a femoral trial head. The ball joint may be an upper and lower housing coupled together. The ball joint houses a central column that may be a part of the lower housing, a circuit board on the column, and sensors. The sensors may be radially arrange around the circuit board at equal distances from the circuit board and equal angular distances from each other. The sensors may be impacted by features on the inner surface of the upper housing so that they may together measure the force on the upper housing. The force magnitude and location at the joint may be determined from the forces measured at the sensors.
