Kinetic assessment and alignment of the muscular-skeletal system and method therefor
First Claim
1. An orthopedic measurement system for kinetic assessment comprising:
- a device having a surface configured to couple to a joint of a musculoskeletal system comprising at least one sensor configured to measure one or more parameters wherein the device includes a tracking system;
a computer configured to receive measurement data from the at least one sensor and the tracking system;
a display coupled to the computer, wherein the display includes a graphical user interface, wherein a memory and one or more processors are configured to execute one or more programs stored in the memory, wherein the computer is configured to receive measurement data from the at least one sensor of the device, wherein the graphical user interface includes a graphical depiction of a portion of a surface of the device that is configured to couple to the joint, wherein a contact point is displayed on the graphical depiction of the portion of the surface of the device, wherein the computer is configured to use the measurement data to calculate a contact point location on the graphical depiction of the portion of the surface of the device, and wherein the contact point is configured to move in real-time corresponding to movement of the joint.

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.
