Abstract
An implant includes an interbody device having a front, a rear, a first lateral side, a second lateral side, a central cavity, and a plurality of bores extending into the rear of the interbody device, each arced bore being configured to receive an arced anchoring member.
Claims20
An implant comprising:
- an interbody device having a front, a rear, a first lateral side, a second lateral side, a central cavity, and a plurality of angled bores extending into the rear of the interbody device;
- wherein each angled bore is configured to receive an arced anchoring member, and
- wherein each arced anchoring member comprises:
- a shaft having a first end and a second end;
- a tip at the first end of the shaft;
- and
- a head at the second end of the shaft, the head comprising a flat surface, a threaded bore extending into the flat surface, and a rounded shoulder, wherein the flat surface is configured to receive a force to move the arced anchoring member within the angled bore, the threaded bore is configured to receive a tool, and the rounded shoulder is configured to engage a surface of the angled bore to guide the arced anchoring member within the angled bore.

An implant comprising:
- a plurality of arced anchoring members;
- and
- an interbody device having a front, a rear, a first lateral side, a second lateral side, a central cavity, and a plurality of arced angled bores each configured to receive one of the plurality of arced anchoring members;
- wherein the interbody device includes a porous portion and a solid portion at least partially surrounding the porous portion proximate the rear, first lateral side, and second lateral side, the solid portion having a higher density than the porous portion, and
- wherein each arced anchoring member comprises:
- a shaft having a first end and a second end;
- a tip at the first end of the shaft;
- and
- a head at the second end of the shaft, the head comprising a flat surface, a threaded bore extending into the flat surface, and a rounded shoulder, wherein the flat surface is configured to receive a force to move the arced anchoring member within the angled bore, the threaded bore is configured to receive a tool, and the rounded shoulder is configured to engage a surface of the angled bore to guide the arced anchoring member within the angled bore.
