Bone cutting system for alignment relative to a mechanical axis
First Claim
1. A bone cutting system for muscular-skeletal joint installation comprising:
- a bone cutting jig wherein the bone cutting jig is coupled to a bone;
a sensored insert configured to measure load and position of load when installed in a prosthetic joint wherein the sensored insert is a prosthetic component, wherein the sensored insert includes a position measurement system, and wherein measurement data is transmitted from the sensored insert;
a bone jig adapter shim configured to couple to the sensored insert where the bone jig adapter shim is configured to couple the sensing insert to the bone cutting jig; and
a remote system configured to receive the measurement data from the sensored insert wherein the measurement data from the sensored insert is used to align the bone cutting jig.

Abstract
A bone cutting system is disclosed that supports one or more bone cuts that are aligned relative to a mechanical axis. The system comprises a first bone cutting jig, a second bone cutting jig, a sensored insert, a bone jig adapter shim, and a device having at least two reference surfaces. The sensored insert includes a three-axis accelerometer to measure position, rotation, and tilt and includes a plurality of sensors to measure a parameter of the muscular-skeletal system. The reference surface device can be an operating table having a first reference surface and a second reference surface that is perpendicular to the first reference surface for referencing the three-axis accelerometer. The bone jig adapter shim can include a tab that fits into a slot of the first or second bone cutting jigs. A remote system receives accelerometer data to calculate offset relative to a mechanical axis.
