Abstract
A structural joint which may be for orthopedic use is effective to simultaneously resist bending and torsional loading. It includes a female member formed with a cone shaped bore and a mouth defining entry into the bore. A male member matingly engageable with the female member has a contoured outer surface which includes a coupling element sized and shaped for mating engagement with the bore. When the male and female members are joined, the coupling element extends to a location within the bore spaced from the mouth and joins, via a smooth surfaced intermediate element, to a transitional element whose transverse dimension is substantially smaller than the mouth of the bore as it extends through and beyond the mouth. The bore and the coupling element may be mutually tapered such that the male and female members become locked together when engaged.
