APPARATUS AND METHODS FOR INSERTING FACET SCREWS

摘要

A method includes inserting a bone fixation device into a patient's body. The bone fixation device includes a first member and a second member movably coupled to the first member. A passageway is defined within a bone tissue after the bone fixation device is inserted and while the bone fixation device is disposed within the patient's body. At least a portion of the first member of the bone fixation device is disposed within the bone tissue along the passageway. The second member of the bone fixation device is moved relative to the first member of the bone fixation device.
