Abstract
Official abstract text for this publication.
A surgical implant comprising a screw element having a screw head, a first thread having a first thread pitch, a second thread having a second thread pitch and an intermediate portion coupling the first and second thread pitches with the first and second thread pitches being different. The implant has a buttressing head associated with the first thread, and it is dimensioned to be larger than a diameter of the first threads to provide external buttressing as the first and second threads compress a first bone and a second bone together.
