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 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 on a curved surface, joint stability, range of motion, and impingement. In one embodiment, the system is for a ball and socket joint of a musculoskeletal system. The system further includes a computer having a display configured to graphical display quantitative measurement data to support rapid assimilation of the information. 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.

Abstract: A medical device may include a lower housing, a printed circuit board (PCB) received within the lower housing, a top housing, two plungers received in gaps within the top housing, and strain gauges mounted to the PCB. The strain gauges may define two polygons aligned with the two plungers. The two plungers may be in contact with the strain gauges such that a force on a plunger is transferred to the strain gauges in contact with the respective plunger. The load magnitude and load location may be determined based on the measured strain of the strain gauges.

Abstract: A surgical apparatus is configured to support at least one bone cut for installation of a prosthetic component. The installed prosthetic component will have reduced alignment error. The surgical apparatus is configured to distract a first compartment to a first predetermined load value while allowing a moving support structure to pivot freely. A distraction lock mechanism is then engaged to prevent movement of a distraction mechanism that raises or lowers the moving support structure relative to a fixed support structure. The moving support structure has M-L tilt angle that is measured. A M-L tilt mechanism is engaged to forcibly equalize the first and second compartments. Engaging the M-L tilt mechanism prevents the moving support structure from freely pivoting. The at least one bone cut relates to the first and second compartments equalized and the M-L tilt angle.

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 system is disclosed to support installation of a prosthetic joint or a prosthetic component. The system includes at least one sensor to measure a parameter. The system uses one or more patient specific instruments in conjunction with a tensor to make one or more bone cuts. The patient specific instruments and tensor make the bone cuts such that an installed prosthetic joint is aligned, balanced, loaded correctly, and positioned optimally for performance and reliability. The use of the tensor simplifies the workflow required when using the patient specific instruments. In one embodiment, the patient specific instruments are bone cutting jigs configured for the patient anatomy.

Abstract: A surgical apparatus configured to be placed in the musculoskeletal system to precisely separate a first bone from a second bone. The surgical apparatus has one or more sensors to measure one or more parameters and supports one or more bone cuts for installing a prosthetic component. The surgical apparatus has at least one distraction mechanism configured to increase or decrease a height between a first support structure and a second support structure. A tilt mechanism comprises the at least one distraction mechanism. The tilt mechanism couples through a first pivot point and a second pivot point and adjusts a tilt of the second support structure relative to the first support structure. In one embodiment, loading applied to the second support structure is distributed between the first pivot point and the second pivot point during operation of the surgical apparatus.

Abstract: A spine measurement system comprising a camera, an encoded collar, and a remote station. A rod is shaped having one or more bends to modify a curvature of a spine. The encoded collar is coupled to the rod. The encoded collar includes a plurality of markings where each marking represents a rod position. The rod and encoded collar are in a field of view of the camera. The camera takes a number of images as the rod rotates at least 360 degrees. The remote station measures the 2D images to produce quantitative measurements that yield a 3D model of the rod shape. The remote station can use the 3D rod shape to determine metrics that relate to how the rod shapes the spine. For example, a Cobb angle can be calculated from the rod shape to determine if the rod yields the desired spine outcome.

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: A measurement device suitable to measure a force, pressure, or load applied by the muscular-skeletal system is disclosed. The measurement module includes a unitary circuit board that couples electronic circuitry to sensors. In one embodiment, the sensors are integrated in the unitary circuit board. Using more than one sensor allows the position of applied load by the muscular-skeletal system to be measured. In one embodiment, the sensors of a sensor array can be elastically compressible capacitors. A load plate can underlie the sensor array. Similarly, a load plate can overlie the load plate. Load plates are rigid structures for distributing a force, pressure, or load. The measurement device can include an articular surface for allowing movement of the muscular-skeletal system. A remote system can be in proximity to the measurement device. The remote system can receive, process, and display data from the measurement module in real-time.
