Abstract
Abstract A bone resection guide for the resection of a bone of a patient. The bone resection guide comprises a body and a resection alignment guide. The body extends between a tool engaging surface and a bone-facing surface superposable to the bone of the patient and is removably securable to the bone of the patient with the bone facing surface superposed thereto. The resection alignment guide defines at least one resection plane and extends along a resection path. The resection alignment guide comprises a plurality of guiding bores extending from the tool engaging surface into at least a section of the body, along the resection path. A method for performing a resection of a portion of a bone of a patient is also provided.
