Abstract
According to an aspect of some embodiments there is provided a bone anchor including an elongated core having a tip at a distal end and coupled to a head at a proximal end, and a segmented helical thread defining one or more gaps therein, each gap defining at least a trailing wall, the trailing wall having a cutting surface including at least one cutting edge. The bone cutting surface and the cutting edge configured to cut bone and guide bone fragments radially inwards. According to an aspect of some embodiments there is further provided a bone anchor kit and a method for implanting the bone anchor in bone.

A bone anchor kit comprising
- at least one bone anchor comprising
- a head;
- a core;
- and
- a segment helical thread defining one or more gaps therein, each gap defining at least a trailing wall said trailing wall having a cutting surface including at least one cutting edge;
- said bone cutting surface and said cutting edge configured to cut bone and guide bone fragments radially inwards;
- at least one bone anchor driving tool;
- and
- at least one bone anchor dedicated drill guide.
A method for implanting a bone anchor in bone comprising
- drilling a bore in a cortical layer of said bone;
- forming a notch in a surface of said bone;
- placing in said bore a bone anchor comprising a core and a segment helical thread defining one or more gaps therein, each gap defining at least a trailing wall said trailing wall having a cutting surface including at least one cutting edge such that at least a portion of said cutting edge is positioned inside said slot;
- rotating and driving said anchor into said bone;
- and
- cutting bone and guiding bone fragments radially inwards.
