The device was not available for evaluation.The imaging provided shows the separation of locking caps from the screw head on the left side at l3 and l5 and on the right side at l5.In addition, the rod on the left side of the construct had bilateral screws at l3 and l5 of a l3-l5 fusion.It is possible that excessive cantilever force was placed on the l3 and l5 screws due to a lack of fixation point at l4 where no screws were placed; however, an exact cause to the reported issue could not be determined.
