Patient underwent revision surgery on (b)(6) 2021 for unspecified reasons at which time it was observed that the posterior fixation construct was loosening in 3-level construct from l4-s1, on both sides.The root cause of this event cannot be determined at this time as no implants were made available for analysis.The reason for the revision surgery is unknown currently.It was noted that dr.(b)(6) replaced all previous hardware and fused up to l3 using the mariner system.Review of labeling: possible adverse events: loosening of spinal fixation implants may occur due to, latent infection, and/or premature loading, possibly resulting in bone erosion, migration, or pain.

During a revision surgery, dr.(b)(6) observed that the posterior fixation construct was loosening in 3-level construct from l4-s1, on both sides.This occurred 6 months post-operatively.Loosening appears to be at the s1 spine level bilaterally based on ct imaging.The index surgery was performed in (b)(6) of 2020.The case was a previous fusion at l5-s1.Dr.(b)(6) replaced all previous hardware and fused up to l3 using the mariner system.
