Abstract
A compression screw comprising a threaded shaft and a head associated with the proximal end of the shaft. The head has a plurality of outwardly extending projections spaced from one another so as to define a plurality of recesses there between for receiving a screw drive in such a way that rotational force may be transferred from the screw drive to the screw. The projections of the head may be provided with suture fixation holes or a suture coupling may be positioned over the shaft so as to extend between the projections of the head.
