An implantable device includes a polymeric body and a metallic first mounting strip connected to a trailing end portion of the body. The body has a leading end portion, a first side surface, a second side surface, an upper surface, a lower surface and a central opening extending through the upper and lower surfaces. The central opening has an internal surface with an internal leading surface, a first internal side surface and a second internal side surface. A first depth is defined between the leading end and the internal leading surface, a first spacing is defined between the first side surface and the first internal side surface and a second spacing is defined between the second side surface and the second internal side surface. The first spacing is substantially the same as the second spacing and the first depth is less than the first spacing. |

1. An implantable device for use in association with bones in a patient's body, the implantable device comprising:
a body constructed of a polymeric material including a trailing end portion, a leading end portion having a leading end, a first side portion having a first side surface, a second side portion having a second side surface, an upper surface and a lower surface, a central opening extending through the body, the central opening having an internal surface including an internal leading surface, a first internal side surface, an internal trailing surface, and a second internal side surface, a first depth defined between the leading end and the internal leading surface, a second depth defined between the internal trailing surface and a trailing end of the trailing end portion, a maximum central opening length defined between the internal trailing surface and the internal leading surface, the maximum central opening length being greater than a sum of the first and second depths, a first spacing defined between the first side surface and the first internal side surface and a second spacing defined between the second side surface and the second internal side surface, the first spacing being substantially the same as the second spacing and the first depth being less than the first spacing, the first side portion including a first opening extending substantially straight through the body, the second side portion including a second opening extending substantially straight through the body, the internal leading surface extending substantially parallel relative to the leading end, the internal leading surface being substantially flat; and a mounting strip constructed of a metallic material connected to the trailing end portion, a first screw hole and a second screw hole extending through the mounting strip. |
