    THE INCIDENT REPORTED UNDER MDR 3005977257-2016-00005, STATED A FOLLOW UP X-RAY FOR AN L5-S1 FUSION SHOWED THAT THE Ø5-7MM SET SCREW (01-80101, LOT# BE08) HAD BACKED OUT OF THE RIGHT INFERIOR (S1) PEDICLE SCREW TULIP (PART#: 02-80081-02 LOT# 8603), A SUB-COMPONENT OF THE PEDICLE SCREW ASSEMBLY (PART#: 01-80169-45R LOT#: 273M) AND WAS FREE FLOATING IN THE SOFT TISSUE. AS A SECOND NOTE THE P-LIFT CAGE HAD MIGRATED POSTERIORLY. THIS IS THE FIRST OF 2 OCCURRENCES INVOLVING A SET SCREW BACKING OUT OF A PEDICLE SCREW ASSEMBLY IN THE SAME PATIENT, THE OTHER OCCURRENCE WAS REPORTED UNDER MDR #: 3005977257-2016-00006. BASED ON THE KNOWN FACTORS OF THE SURGICAL EVENT, THE SURGERY WAS PERFORMED IN COMPLIANCE WITH SPINEFRONTIER'S SURGICAL TECHNIQUES AND IFU. THE SHE Ø5-7MM SET SCREW PART #: 01-80101, LOT #: BE08A INSPECTION DATA SHOWS THAT THE SET SCREW CONFORMS TO THE DRAWING AND ALL PARTS FROM THE CONSTRUCT PASSED FUNCTIONAL FIT CHECKS. THE RISK MANAGEMENT FILES ASSOCIATED WITH THE DEVICE HAD SHOWN THAT THIS FAILURE MODE HAD BEEN ANALYZED AND WAS RATED ALARP WITH AN OCCASIONAL OCCURRENCE, WHICH IS IN LINE WITH WHAT HAS OCCURRED. SPINEFRONTIER MITIGATED THE RISK AS LOW AS REASONABLY POSSIBLE AND ALL SUPPORTING MITIGATIONS WERE IN PLACE AND SUFFICIENT. IN CONCLUSION, THIS IS AN EVENT THAT MAY HAPPEN WITH AN OCCASIONAL OCCURRENCE AND DOES NOT WARRANT ANY FURTHER ACTION. THE OTHER COMPONENT ASSOCIATED WITH THIS EVENT (PEDICLE SCREW TULIP ASSEMBLY PART#: 01-80169-45R LOT#: 273M) WAS REPORTED UNDER MDR #: 3005977257-2016-00003.
