Abstract
A threaded implant can be provided with an elongated main body having external threads configured to thread into bone, and an internal support structure located within the external threads. The internal support structure has a helical arrangement that extends in an opposite direction to the external threads. Other threaded implants and methods are also disclosed.
Claims17
A threaded implant, comprising:
- an internal support extending axially along at least a portion of the implant;
- an external thread extending radially outward relative to the internal support;
- and
- a helically configured porous infill extending radially outward relative to the internal support and disposed helically between the external thread,
- the helically configured porous infill comprising a plurality of pores sized to provide for one or more of bony on-growth, ingrowth or through-growth.

A threaded implant, comprising:
- an internal support extending axially along at least a portion of the implant;
- an external thread extending radially outward relative to the internal support;
- and
- a helically configured scaffolding extending radially outward relative to the internal support and disposed helically between the external thread,
- the helically configured scaffolding comprising a plurality of pores sized to provide for one or more of bony on-growth, ingrowth or through-growth.
2 more elements
A threaded implant, comprising:
- an external thread extending along at least a portion of a length of the implant;
- and
- a helically configured porous infill disposed helically between the external thread, the helically configured porous infill comprising a plurality of pores sized to provide for one or more of bony on-growth, ingrowth or through-growth, the external thread and the helically configured porous infill manufactured from the same material and manufactured together during the same additive manufacturing process.
