Claims20
An implantable device comprising:
- a spacer comprising a superior surface, an inferior surface, a side extending therebetween, and a passage extending through the side, the passage having a groove comprising a generally helical shape, the passage having a substantially straight longitudinal axis through its entire length;
- and
- a fixation device consisting of a helically-shaped body of a single wire,
- wherein the groove comprising the generally helical shape is configured to guide and house the single wire when the single wire extends through the passage and into a bony structure to secure the spacer to a bone.

A method for treating a spine, comprising:
- Inserting a spacer between two vertebral bodies, the spacer comprising a superior surface, an inferior surface, a side extending therebetween, and a passage extending through the side, the passage having a groove comprising a generally helical shape, the passage having a substantially straight longitudinal axis through its entire length;
- and
- Inserting a fixation device consisting of a helically-shaped body of a single wire through the passage to secure the spacer to a vertebral body, wherein the groove comprising the generally helical shape guides and houses the single wire.
An implantable device comprising:
- a spacer comprising a superior surface, an inferior surface, a side extending therebetween, and a passage extending through the side, the passage having a generally helical-shaped groove;
- and
- a fixation device consisting of a helically-shaped body of a single wire having an outer surface,
- wherein the generally helical-shaped groove is configured to engage the outer surface of the single wire when the single wire extends through the passage, the fixation device having a substantially straight longitudinal axis when extending through the passage.
