Patent ID: 7338532

Claim:
An alignment assembly for a modular orthopedic prosthesis, the alignment assembly comprising: a substantially planar base component connectable to a first prosthetic component, the base component defining first and second external dovetail recesses and first and second externally open channels on opposite first and second outer surfaces of the base component, the first dovetail recess oriented along a first axis and having a first recess length, the second dovetail recess oriented along a second axis nonparallel relative to the fist axis and having a second recess length, the first channel substantially parallel to the first dovetail recess and separated from the first dovetail recess by a first deformable locking bar, the second channel substantially parallel to the second dovetail recess and separated from the second dovetail recess by a second deformable locking bar; a connecting first component slidably couplable with the base component, the first component having a dovetail projection with a solid dovetail cross-section extending from a first outer surface of the first component, the dovetail projection slidably receivable in and mateable to one of the first and second dovetail recesses of the base, the dovetail projection having a length that is less than any one of the first or second recess lengths, such that when the first component is coupled to the base component, a first portion of the corresponding dovetail recess is engaged with the dovetail projection and a remaining portion of the corresponding dovetail recess is open; a substantially planar slider plate having a solid dovetail cross-section, the slider plate slidably receivable in and mateable to any one of the first or second of the dovetail recesses and having length substantially equal to the remaining portion of the corresponding recess when the first component is coupled to the base, the slider plate operable to stabilize the remaining portion of the recess; and at least one set screw transversely insertable through one of the first or second channels and operable to deform the corresponding locking bar and lock the first component to the base component.
