Bone cutting system for alignment relative to a mechanical axis

A bone cutting system for muscular-skeletal joint installation comprising:

• a first bone cutting jig having a slot;
• a sensored insert configured to measure load and position of load;
• a bone jig adapter shim configured to couple to the sensing insert where the bone jig adapter shim includes a tab configured to couple to the slot of the first bone cutting jig;
• and
• a remote system configured to receive data from the sensored insert.

A bone cutting system comprising:

• a first bone cutting jig configured to couple to a first bone;
• a sensored module configured to measure a parameter of the muscular-skeletal system where the sensored module includes at least one three-axis accelerometer configured to measure position, rotation, and tilt;
• an adapter configured to couple to the sensored module to the first bone cutting jig;
• and
• a remote system configured to receive data from the at least one three-axis accelerometer to support alignment of the cutting jig to a mechanical axis.
