Abstract
A system and method for further improving upon an ability of a surgeon to reduce or eliminate impaction forces when installing or assembling a prosthesis. An implant includes a surface treatment for aiding operations with the implant. For example, some surface treatments provide an asymmetry in installation versus removal to bias the associated implant deeper into an installation site.
Claims5
A method for producing a prosthesis for an installation of the prosthesis into a relatively undersized cavity, the relatively undersized cavity providing a resistive force for installation of the prosthesis into the relatively undersized cavity, comprising:
- a) manufacturing additively a structure for the prosthesis, said structure including a foundation and a surface;
- and
- b) during said manufacturing step a) establishing one or more portions of said structure configured to produce an increased propensity for insertion of the prosthesis into the relatively undersized cavity during the installation, said propensity for insertion responsive to a set of exterior surface structures that extend, relative to an insertion path, that include a pitch having a monotonic varying spacing over said surface parallel to said insertion path, said pitch providing for a set of asymmetric relative installation forces.
