Abstract
A bone incision block includes an incision guide, a localization reference adjustably attached to the incision guide, a fastener for fastening to a bone, and an adjustment device. The incision guide defines an incision plane, and the localization reference enables the incision plane to be spatially determined. The adjustment device is operatively coupled between the fastener and the incision guide, wherein the incision plane can be set relative to the bone via the adjustment device, and a spatial position of the adjustment device can be determined via a registration element.

A bone incision block, comprising:
- an incision guide that defines an incision plane;
- a localization reference rotatably attached to the incision guide, said localization reference enabling the incision plane to be spatially determined;
- a fastener for fastening to a bone;
- an adjustment device operatively coupled between the fastener and the incision guide, wherein the incision plane can be set relative to the bone via the adjustment device, and wherein adjusting movement of the incision guide relative to the fastener results in a corresponding movement of the localization reference;
- and
- a registration element for determining a spatial position of the adjustment device, said registration element independent from said localization reference.
