Abstract
A first member (10,10′,10″) has a bore formed with a self holding taper which receives the post of a second member (14,14′,14″) formed with a matching self holding taper. A bacterial/endotoxin-seal is provided by having a portion of either the bore, contiguous to its mouth, or the post, at a location which corresponds to the location of the mouth of the bore when in the locked position, provided with a sealing taper (10c,16c) with a different angle selected to form an interference fit. The sealing taper (10c,16c) extends only along a minor portion of the longitudinal axis of the respective bore and post. The first member (10,10′,10″) is provided with an outer surface to promote osseointegration when used in bony sites.
