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 system and method for measuring medial-lateral tilt of a bone is disclosed. The bone is coupled to a joint of the muscular-skeletal system. The method comprises coupling a three-axis accelerometer to a prepared bone surface of a bone. The three-axis accelerometer is configured to measure position, rotation, and tilt. The joint is rotated between two points. The rotation between the two points traverses an arc having a maximum therebetween. The joint pivots off of a surface to which the bone is coupled. In one embodiment, a pivot point and joint rotation relates to a mechanical axis of the joint and bone. The three-axis accelerometer measures data points along the arc as it is rotated between the two points. Multiple passes along the arc generates sufficient data points to determine the maximum. The position of the maximum is used to calculate the medial-lateral tilt of the bone.

Abstract: A system and method for adjusting a contact point of a joint is disclosed.

Adjustment of the contact point of the prosthetic component can be performed by repositioning the prosthetic component relative to a bone to which it is coupled. For example, a prosthetic component can be pinned to the bone allowing rotation of the prosthetic component relative to the bone in-situ. A remote system receives sensor data from the prosthetic component allowing viewing of the load magnitude, position of load, and rotation of the prosthetic component.
