Quantitative assessment of prosthesis press-fit fixation
A system and method for quantitatively assessing a press fit value (and provide a mechanism to evaluate optimal quantitative values) of any implant/bone interface regardless the variables involved including bone site preparation, material properties of bone and implant, implant geometry and coefficient of friction of the implant-bone interface without requiring a visual positional assessment of a depth of insertion. The following description is presented to enable one of ordinary skill in the art to make and use the invention and is provided in the context of a patent application and its requirements.

Acetabular apparatus with dual mobility for hip revision surgery
Prostheses, acetabular apparatuses, and methods of use are disclosed. In some embodiments, an acetabular apparatus includes an acetabular cup, a pre-assembled liner and flange construct, and a dual mobility bearing (e.g., a dual articulating femoral head component and insert). In one embodiment, the pre-assembled liner and flange construct may be coupled together by a band coupled to the flanges, the band being arranged and configured to be pressed onto an outer surface of a liner. The pre-assembled liner and flange construct being arranged and configured to accept the dual mobility bearing so that it is freely rotatable relative thereto during use.

Laser-produced porous surface
The present invention disclosed a method of producing a three-dimensional porous tissue in-growth structure. The method includes the steps of depositing a first layer of metal powder and scanning the first layer of metal powder with a laser beam to form a portion of a plurality of predetermined unit cells. Depositing at least one additional layer of metal powder onto a previous layer and repeating the step of scanning a laser beam for at least one of the additional layers in order to continuing forming the predetermined unit cells. The method further includes continuing the depositing and scanning steps to form a medical implant.
Augments, systems and methods for acetabular implants
The augments, systems and methods for supporting acetabular implants described herein can include an augment (100) for supporting an acetabular shell (90) having a first portion (136) of a locking mechanism. The system can also include a shell having a second portion of a locking mechanism (96). The first portion of the locking mechanism and the second portion of the locking mechanism can be adapted to move relative to one another from an unlocked state to a locked state to fixedly couple the augment to the shell. In some examples, the augment can be contourable to match the shape of a bone.

Total joint replacement infection control devices and methods
An orthopedic system for delivery of a therapeutic agent to a bone includes an elongate stem adapted to be inserted into an intramedullary canal, an inlet configured to receive the therapeutic agent, and one or more outlets configured to deliver the therapeutic agent to the bone. The elongate stem may comprise one or more protrusions to engage the bone, and one or more channels extending longitudinally therein, fluidly coupled to the inlet. The therapeutic agent flows from the inlet through the one or more channels and exits into the intramedullary canal through the one or more outlets. The system may be configured to allow one or more dimensions of the system to be adjusted to accommodate the anatomy of a patient.
