Abstract: A single use cutting jig for use in cutting a bone in orthopaedic surgery, the cutting jig having: a first face shaped to receive the end of the bone to be cut, a second face provided with one or more cutting slot, the or each slot extending through the cutting jig from the second face to the first face and being shaped for receiving a cutting device, wherein the cutting jig is molded from plastic, and wherein the interior surface of the or each cutting slot is provided with a metal coating.

Abstract: A surgical device for holding and rotating an acetabular reaming head is provided, comprising a shaft having a length which runs from a first end adapted for holding an acetabular reaming head to a second end. At least part of the shaft is divergent from the axis defined by the first and second ends of the shaft, for example the shaft may include a C-shaped divergent portion. A head held by the device can therefore access the acetabular in its true anatomical position while avoiding encroachment of the shaft on surrounding body parts.
