Abstract
A surgical screw according to an exemplary aspect of the present disclosure includes, among other things, a shaft portion that extends between a proximal end and a distal end, the shaft portion including a first thread having a variable pitch and a head portion extending from the proximal end of the shaft portion. The head portion includes a second thread having a pitch that is equal to a pitch of at least a portion of the variable pitch.
Claims1
A surgical method, comprising:
- positioning a bone plate against a fractured bone such that the bone plate is generally parallel to a fracture line of the fractured bone;
- inserting a surgical screw through an opening of the bone plate such that the surgical screw extends across the fracture line between a first fragment and a second fragment of the fractured bone;
- during insertion of the surgical screw, imparting compression across the fracture line to draw the first fragment and the second fragment closer together with a shaft portion of the surgical screw that includes a thread having a variable pitch;
- and
- engaging the opening of the bone plate with a head portion of the surgical screw to substantially lock the bone plate to the fractured bone.
