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 μm 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. |
