APPARATUS AND METHODS FOR INSERTING FACET SCREWS
First Claim
1. An apparatus, comprising:
- an insertion tool having a proximal end portion and a distal end portion, the distal end portion of the insertion tool configured to retain a bone fixation device, the proximal end portion of the insertion tool defining a threaded opening; and
a guide wire having a proximal end portion and a distal end portion, at least a portion of the guide wire configured to be disposed within the insertion tool such that the distal end portion of the guide wire is disposed outside of and spaced apart from the distal end portion of the insertion tool, the proximal end portion of the guide wire including a threaded portion configured to be disposed within and engage the threaded opening of the insertion tool.

Abstract
An apparatus includes an insertion tool and a guide wire. The insertion tool has a proximal end portion and a distal end portion. The distal end portion of the insertion tool is configured to retain a bone fixation device. The proximal end portion of the insertion tool defines a threaded opening. The guide wire has a proximal end portion and a distal end portion. At least a portion of the guide wire is configured to be disposed within the insertion tool such that the distal end portion of the guide wire is disposed outside of and spaced apart from the distal end portion of the insertion tool. The proximal end portion of the guide wire includes a threaded portion configured to be disposed within and engage the threaded opening of the insertion tool.

8. An apparatus, comprising:
-
a first shaft having a proximal end portion and a distal end portion, the distal end portion of the first shaft configured to engage a nut; a second shaft having a proximal end portion and a distal end portion, the distal end portion of the second shaft configured to engage a screw, at least a portion of the distal end portion of the second shaft disposed within the first shaft, the first shaft configured to rotate about the second shaft to rotate the nut about the screw; and a guide wire having a proximal end portion and a distal end portion, at least a portion of the guide wire disposed within the second shaft such that the distal end portion of the guide wire is disposed outside of and is spaced apart from the distal end portion of the second shaft. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method, comprising:
-
inserting percutaneously a distal end portion of an insertion tool and a bone fixation device, the bone fixation device having a proximal end portion and a distal end portion, the proximal end portion of the bone fixation device removably coupled to the distal end portion of the insertion tool, the insertion tool including a guide member disposed within the bone fixation device such that a distal end portion of the guide member is spaced distally from the distal end portion of the bone fixation device by a first distance; advancing the guide member into a bone tissue by a second distance; and moving, after the advancing, the guide member relative to the insertion tool and the bone fixation device such that the distal end portion of the guide member is spaced distally from the distal end portion of the bone fixation device by a third distance greater than the first distance. - View Dependent Claims (15, 16, 17, 18, 19, 20)
