Abstract
A vertebral facet distractor includes an elongated generally cylindrical contour including a first end surface, a second end surface, an outer sidewall, an inner sidewall, and a central lumen having an opening in one of the first end surface and the second end surface. The outer sidewall may be provided with a surface irregularity, such as a screw thread. The vertebral facet distractor may further include a holder including an elongated body and a tip that extends through the opening and is engaged with the contour. The tip may be provided with a screw thread that is engaged with the contour or may engage the contour in an interference fit.
Claims8
A vertebral facet distractor intended to be positioned between first and second articular facets in an articular facet joint to provide distraction between the first and second articular facets, the vertebral facet distractor comprising:
- an elongated generally cylindrical contour including a first axial end surface, a second axial end surface, an outer cylindrical sidewall, an inner cylindrical sidewall, and a central lumen having an opening in one of the first axial end surface and the second axial end surface, wherein the central lumen extends at a non-perpendicular angle relative to the first axial end surface and the second axial end surface.
An assembly of a vertebral facet distractor intended to be positioned between first and second articular facets in an articular facet joint to provide distraction between the first and second articular facets and a holder, the assembly comprising:
- a vertebral facet distractor intended to be positioned between first and second articular facets in an articular facet joint to provide distraction between the first and second articular facets, the vertebral facet distractor including an elongated generally cylindrical contour including a first axial end surface, a second axial end surface, an outer cylindrical sidewall, an inner cylindrical sidewall, and a central lumen having an opening in one of the first axial end surface and the second axial end surface, wherein the central lumen extends at a perpendicular angle relative to the first axial end surface and the second axial end surface;
- and
- a holder including an elongated body and a tip that extends through the opening and is engaged with the contour.
