摘要

A device (10) for use in orthopaedic surgery includes a metallic central member (30). The device also includes an outer portion (20) comprising a polymer, which can be moulded around the metallic central member. The outer portion thus surrounds the metallic central member. The outer portion has a profiled outer surface (40), such as teeth, ribs or ridges for removing bone. Engagement features for resisting relative movement between the metallic central member and the outer portion can comprise ridges, grooves (34, 36) and apertures (32) of the metallic central member, filled with polymer. The device can be a broach or rasp. A surgical instrument kit includes a plurality of differently sized devices of the kind described herein.
