Abstract:
1. A distal wrist implant comprising: a head for resurfacing a distal end of an ulna having a first coupling portion including opposing surfaces that define a slot, the head defining a passage that extends from an outer surface of the head to the slot, the head further defining a hole at a distal aspect thereof configured for receipt of one of a natural soft tissue replacement and an artificial soft tissue replacement; a stem adapted to be coupled to a prepared ulna, the stem having a second coupling portion extending upwardly from a surface of the stem, the second coupling portion including first and second sides extending substantially parallel to each other, the second coupling portion non-rotatably receivable within the first coupling portion to couple the head to the stem in a coupled position, wherein the second coupling portion has a third side, a fourth side opposite the third side, and a fifth side, the third, fourth and fifth sides all extending between the first and second sides, the second coupling portion further including an angled wall that non-orthogonally extends between the fourth side and the fifth side, the angled wall aligning with the hole in the head in the coupled position and accommodating receipt of one of the natural and artificial soft tissue replacements between the angled wall and the head, wherein the second coupling portion defines a bore that cooperatively aligns with the passage in the coupled position; and a fastener that selectively extends through the passage and the bore to secure the head to the stem.
