A connection for components in a medical implant assembly utilizes a tapered mating surface on each component with cylindrical splines and flutes formed on each mating surface such that the surfaces are complementary to the extent that the splines of one surface are received in the flutes of the adjacent surface. Each surface is continuous with no discontinuity which would act as a stress raiser or enhance concentration of stress in one locale. The complementary surfaces are urged into registry by a screw connection coaxially through the surfaces.

An improvement in the connection between mating components in medical implants wherein said components are subjected to torsional loads, comprising an interface defining a mating relationship between adjacent surfaces of said components wherein one of said surfaces defines a splined truncated cone tapering from a major diameter to a minor diameter and an annular shoulder circumscribing said major diameter, wherein said cone circumscribes an opening for a threaded receptacle for a threaded fastener.
