In one form, the fins have a curvature that extends away from the stem portion. In another form, the first arm defines an opening sized to receive an anchor wherein the anchor is configured to penetrate a portion of bone and the opening in the first arm. Optionally, the stem portion includes a first portion (1022) having a first cross sectional area and a second portion (1024) having a second cross sectional area wherein the first cross sectional area is larger than the second cross sectional area. The fins and arms can include rail protrusions (1186).
