Abstract: A titanium body (2) of a femoral nail incorporates an opening (3) leading into a hollow region (4) which defines a cavity in which electronics may be incorporated. A potting compound overlays the electronics, within the region (4). A 100 to 150 ?m thick cover (18) made from polyetheretherketone is arranged to overlay the opening (3) and close the hollow region (4). The cover (18) is made from flat polyetheretherketone film of suitable thickness which is heat shrunk onto a former and then machined to define the desired shape.

Abstract: Pellets or granules comprise polymeric material, for example polyetheretherketone and a fugitive material, for example sodium chloride. The granules may be used in injection moulding to produce shapes for use in medical implants and may conveniently be used to form parts which are partially porous, or to prepare porous films.
