LATERAL PLATE AND SPINAL IMPLANT SYSTEM AND METHOD

摘要

A lateral plate assembly has an elongated lateral plate for attachment to adjacent vertebrae having a first end portion and a second end portion and a pair of apertures for receiving a first and a second bone screw. The pair of apertures includes a first aperture which is an opening positioned in the first end portion for receiving the first bone screw and a second aperture which is a slotted opening to receive the second bone screw. The second end portion of the lateral plate has an open end with channelled internal sides for receiving and holding a moveable washer on top of the slotted opening. The washer is configured to move along a length of the slotted aperture. The moveable washer has an opening for holding a head of the second bone screw. Movement of the washer relative to the slotted opening increases or decreases the distance between locations of the respective screw heads.
