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 and/or foundational structural regions for aiding operations with the implant. For example, some surface treatments and foundational structural regions provide an asymmetry in installation versus removal to bias the associated implant deeper into an installation site.
Claims7
A method for producing a prosthesis for installation into a medullary cavity of a bone, the cavity providing a resistive force for installation, comprising:
- a) manufacturing additively an elongate structure for the prosthesis, said elongate 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;
- wherein a first portion of said one or more portions includes a first region of said foundation, wherein a second portion of said one or more portions includes a second region of said foundation, and wherein said first portion and said second portion are cooperatively configured to produce a two-dimensional asymmetric stiffness implementing said bias for insertion into the medullary cavity.
An implant for insertion into a medullary cavity of a bone, the cavity providing a resistive force for installation, comprising:
- an elongate structure including a proximal end, a distal end spaced apart from said proximal end, a longitudinal axis extending between said ends, and a portion having a foundational bias for installation into the cavity;
- and
- a first set of regions of said elongate structure and a second set of regions of said elongate structure;
- wherein said regions are cooperatively configured to produce a two-dimensional asymmetric stiffness implementing said foundational bias for insertion into the medullary cavity.
