Abstract
An orthopaedic surgical instrument comprising an orthopaedic cutting block includes a metallic bearing insert configured to support a bone cutting tool and a body molded to the bearing insert. The bearing insert includes a plurality of chemically etched holes, and the body is molded to the bearing insert such that each of the plurality of chemically etched holes is at least partially filled by a portion of the body. The body of the orthopaedic cutting block may include a bone-facing surface adapted to contact a portion of a patient's bone, and the bearing insert may be positioned to allow a surgeon to perform a cut on the patient's bone using the bearing insert for support. A method of manufacturing an orthopaedic surgical instrument is also disclosed.
