Manufacturer Narrative
|
Two locking caps along with related hardware were returned for evaluation.Imaging provided shows rod motion relative to the l5 screws bilaterally only.This may indicate the occurrence of rod slippage.Each interconnection at the l3 and l4 screws appears to remain fixed.There is no clear visual indicator that any locking cap has fully dislodged from a screw head, however observations of wear markings on the bottom of each locking cap indicate loading likely occurred primarily around the cap outer edge.This would indicate that those screw heads had not normalized to the rod which may have contributed to loosening.However the exact cause of the reported issue could not be determined.
