1. A bone implant comprising:
a body elongated along a longitudinal axis between a proximal end of the body and a distal end of the body, the body comprising a rounded exterior surface portion disposed proximal to the first end and having a rounded cross-section transverse to the longitudinal axis;
a head integrally formed on the proximal end of the body, the head including a major diameter larger than the rounded cross-section, the head having a peripheral lower surface that has a substantially spherical portion;
a bore extending through the entire body along the longitudinal axis and opening through both the proximal end and the distal end of the body;
a thread winding around at least a portion of the rounded exterior surface portion of the body; and
a plurality of windows disposed along a portion of the body and forming openings between adjacent portions of the thread winding extending from the bore and through the rounded exterior surface portion, each window of the plurality of windows incrementally changing in size from a proximal end to a distal end of the portion of the body, wherein a major axis of each window of the plurality of windows is increasingly greater than a minor axis of the window from the proximal end to the distal end of the body.
