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.
Claims17
A method for installing a prosthesis into an undersized cavity, the undersized cavity providing a resistive force for installation, comprising:
- a) preparing a surface treatment for the prosthesis in advance of an installation of the prosthesis into the undersized cavity defining a surface-treated prosthesis;
- and
- b) installing said surface-treated prosthesis into the undersized cavity using an installation force less than the resistive force responsive to said surface treatment.
5-6. (canceled)
A method for producing a prosthesis for installation into an undersized cavity, the undersized cavity providing a resistive force for installation, 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 with a bias for installation.
A prosthesis, comprising:
- a structure including a foundation and a surface treatment;
- wherein said surface treatment is configured for a first asymmetric installation bias favoring an installation over an extraction of said structure into a portion of prepared bone.
