Abstract
A jig for trialing a head and conjoining portion of a humeral (shoulder) prosthesis and transferring the spatial positioning to a final implant allows a surgeon to adjust humeral head position thereof in three-dimensional space with respect to a humeral component of the humeral prosthesis that has been either previously implanted into a humerus of a patient or not. The jig utilizes a rotatable body such as a sphere that is non-translatable relative to a jig body. A trial implant construct, having a head and neck that is fixed relative to one another (is spatially positioned), is placed in the jig with the neck thereof in contact with the rotatable sphere. As the head is caused to align with markings on the jig and situated flush with the jig, the rotatable sphere replicates the angular position of the neck with respect to a fixed position head. A final implant construct whose components are not fixed relative to one another, is placed in the jig which automatically transfers the spatial positioning of the trial implant construct to the final implant construct.
