An instrument for use in implanting a joint prosthesis into a bone includes a rod (12) having a proximal end and a distal end, the proximal end includes a visual indicator (16). The instrument also includes a housing (11), such that the rod is moveable in a longitudinal direction relative to the housing. The visual indicator is capable of emitting light when the instrument is in use. As the rod moves in the longitudinal direction, the visual indicator enters into the housing, causing the light emitted to disappear. |
