椎間関節治療のためのシステム

摘要

A method of treating a facet joint of a patient. The facet joint includes a superior articular face and an inferior articular face. An implant is secured to an implant insertion tool by mating a first engagement feature on the implant with a second engagement feature on the implant insertion tool. A distal end of a guide cannula is positioned proximate the facet joint. The guide cannula has an internal passage extending therethrough. The implant slides through the guide cannula passage until the implant passes through a distal end of the guide cannula passage and is at least partially between the superior articular face and the inferior articular face. A force of at least 1 Newton is exerted on the implant insertion tool to separate the first engagement feature and the second engagement feature.
