Claims8
A bone fusion device, comprising:
- a shaft including a porous section and a threaded proximal section configured for facilitating a compression;
- and
- a head threadably connected to the threaded proximal section, the head including a driving feature configured to be engaged by a tool to rotate the head and a plurality of teeth configured for engaging with a bone, at least one of the plurality of teeth being directly threadably engaged with the threaded proximal section, the bone fusion device being formed as a fastener, the head extending from a first longitudinal end to a second longitudinal end and comprising an unthreaded external surface that extends from the first longitudinal end to the second longitudinal end, wherein the plurality of teeth are formed in the second longitudinal end and the driving feature is located at the first longitudinal end, wherein the head is a monolithic structure and a diameter of the head taken at the external surface at the plurality of teeth is the greatest diameter of the head, and the shaft has an externally threaded distal section.
