VERTEBRAL FIXING SYSTEM

摘要

Embodiments disclosed herein provide a method of placing a vertebral fixing system on a vertebra. The vertebral fixing system comprises a connecting part with members forming a space into which a rod may be inserted. The members are moveable relative to each other. A portion of a ligature may be passed through the connecting part to form a loop extending from the connecting part. When the rod is inserted in the space between the members, the ligature may be tensioned against the rod. The members of the connecting part may be driven together to hold the ligature in place. An adjustable locking means may be utilized to fix simultaneously in position the connecting part relative to the rod and at least one portion of the ligature relative to the connecting part, so as to prevent relative displacement of the rod and the vertebra in opposite directions.

主权项

1. A vertebral fixation system comprising:
a spinal rod; a connecting part including a transverse passage sized to receive the spinal rod therethrough; a flexible ligature having a first end region extending to a first end of the flexible ligature, a second end region extending to a second end of the flexible ligature, and an intermediate region extending between the first end region and the second end region; wherein at least one of the first end region and the second end region extends from a first opening of the connecting part, and the intermediate region forms a loop extending from a second opening of the connecting part; and an adjustable locking screw threadably engaged in a threaded bore hole of the connecting part; wherein tightening the adjustable locking screw in the threaded bore hole causes the spinal rod to press against the flexible ligature.
