A facet joint distraction system, comprising:
- a facet joint delivery device comprising:
- a shaft;
- and
- a pair of tines extending from a portion of the shaft, each tine comprising a tapered end tip and serrations or teeth along at least a portion of a length of each tine and adapted to engage and anchor at a spinal facet joint;
- and
- a driver assembly comprising:
- an elongated shaft;
- and
- opposing first and second implant engagement portions each extending from a distal portion of the elongated shaft, the implant engagement portions both adapted to engage a proximal end surface of a spinal facet joint implant,
- wherein at least a portion of the driver assembly is adapted to be received by the shaft of the delivery device and the delivery device is adapted to deliver the spinal facet joint implant into the spinal facet joint to distract the spinal facet joint.
A kit comprising:
- a facet joint delivery device comprising:
- a shaft;
- and
- a pair of tines extending from a portion of the shaft, each tine comprising a tapered end tip and serrations or teeth along at least a portion of a length of each tine and adapted to engage and anchor at a spinal facet joint;
- and
- a driver assembly comprising:
- an elongated shaft;
- and
- opposing first and second implant engagement portions each extending from a distal portion of the elongated shaft, the implant engagement portions both adapted to engage a proximal end surface of a spinal facet joint implant,
