Abstract
A method of forming a composite titanium body for use in forming spinal implant interbodies includes selecting a metal alloy body, carving out a top portion and a bottom portion from the metal alloy body, and bonding a porous material to the carved-out top and bottom portions. Multiple pieces may be cut from the composite titanium body, each having a front face formed of the metal alloy, top and bottom portions formed of the porous material, and with a medial portion of the metal alloy extending from the front face to the back. Methods and devices for spinal interbodies having locking mechanisms to prevent bone screw back-out are also described.
Claims20
A method of manufacturing a composite interbody, the method comprising:
- selecting a solid titanium body having a top side and a bottom side;
- carving out a portion of the top side of the solid titanium body to form a top portion void;
- carving out a portion of the bottom side of the solid titanium body to form a bottom portion void;
- diffusion bonding porous titanium to the top portion void;
- diffusion bonding porous titanium to the bottom portion void, the steps of diffusion bonding porous titanium to the top portion void and bottom portion void forming a composite titanium block;
- and
- cutting out a composite interbody from the composite titanium block.
