Posterior cervical fusion system and techniques

摘要

A posterior cervical fusion surgery assembly and method. The assembly includes a sled adapted to be positioned in a facet joint and two receivers slidably mounted on the sled. The receivers are adapted to support surgical instruments such as a drill, a tap, and a screw. The sled assists in orienting the instruments at a desired angle with respect to the spine.

主权项

1. A posterior cervical fusion surgery assembly comprising:
a facet sled including a sled end having an anterior side, a posterior side opposite the anterior side and first and second lateral sides, said sled end being adapted to be inserted into a vertebral facet joint between a superior facet and inferior facet of a patient, the posterior side of the sled end including a guide having a height that is greater than the maximum height of the anterior side and configured to engage the posterior aspects of the superior and inferior facets and the first lateral side including a guide having a height that is greater than the maximum height of the second lateral side and configured to engage the lateral aspects of the superior and inferior facets; and an elongated handle extending from the posterior side of the sled end, the sled defining a longitudinal direction; a first extension slidably coupled to the elongated handle of the facet sled and configured for placement adjacent the superior facet; and a second extension slidably coupled coupled to the elongated handle of the facet sled and configured for placement adjacent the inferior facet; the first and second extensions adapted to support surgical instruments.
