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.

A structural joint comprising: a female member having an elongated generally right circular cone shaped bore therein with a mouth defining entry into the bore; and an elongated male member matingly engageable with said female member having a contoured outer surface extending between a terminal end and an inboard region, said male member including: a generally right circular cone shaped coupling element adjacent said terminal end congruently sized and shaped relative to the bore in said female member for mating engagement with the bore and, when joined with said female member, extends to a location within the bore spaced from the mouth thereof; a transitional element having a transverse dimension substantially smaller than the mouth of the bore extending longitudinally of said male member from a location within the bore spaced from the mouth thereof to a location beyond the mouth of the bore when said male member is joined with said female member; and an intermediate element having a smooth convex shaped outer surface of continuous curvature interconnecting said coupling element and said transitional element such that upon the application of bending stresses on said male member, said convex shaped outer surface of said intermediate element is caused to rollingly engage the bore of said female member.
