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.
