SPINAL FIXATION DEVICE WITH LATERALLY ATTACHABLE CONNECTORS |
摘要 |
A spinal fixation device (10) includes a threaded stud (24) having an open- ended axial slot (30) to straddle a rod (14) of a vertebral support (12), an d a bracket (22) which is rotatable on the stud (24). A vertebra bone screw (5 0) passes through an opening (48) in a distal end of the bracket (22). The stud (24) and bracket (22) are locked in position relative to the rod (14) by a n ut (34). An insert (32) within the slot (30) bears against the rod (14) and prevents the stud (24) from being deformed by the force of the nut (34) on t he stud segments. The bracket (22) can be be rotated around the stud (24); and the stud (24) can be rotated around and slid along the rod (14), to afford great adjustability and ease of attachment.
