Prosthesis installation and assembly

An assembly method for a multicomponent modular prosthesis including a first end component, a second end component, and a set of intermediate components configured to be joined collectively to both of the end components, each intermediate component including a pair of mechanical joinder interfaces and each end component including at least one mechanical joinder interface, with each mechanical joinder interface defining an assembly axis, comprising:

• defining a number N of assembly phases, each phase joining a series of aligned assembly axes of contiguous components, where N identifies a number of sets of non-aligned assembly axes;
• and
• compressing, for each phase, said series of aligned assembly axes of contiguous components, responsive to an application of an assembly force applied to an assembly structure configured to align series of aligned assembly axes of contiguous components and maintain said alignment, during said application of said assembly force;
• and
• wherein a set of grip structures are disposed on one or more of the components, at least one said grip structure for each aligned assembly axis;
• and
• wherein each said grip structure of said set of grip structures includes a self-centering apex;
• and
• wherein each of the assembly axes is aligned with at least one said self-centering apex of at least one of said grip structures of said set of grip structures during said application of said assembly force of each said phase, configured for a mechanical joining of a set of mechanical joinder interfaces with each said assembly axis of said mechanical joinder interfaces of said set of mechanical joinder axes aligned with each other.
