Ct confirming the event was received.Dhr review and product investigation cannot be completed as the product has not been returned because the device was discarded by the hospital.It is unknown if the patient complied with post-op care instructions.There was no report that the patient sustained an impact/trauma of some sort.Patient was refixated to correct the problem.Review of labeling notes: "intraoperative warnings.If the construct contains screws, prior to soft tissue closure, recheck all screws to ensure they are tightened.Failure to do so may cause loosening of the other components.Postoperative warnings: the patient should be advised to limit and restrict physical activities, especially lifting and twisting motions and any type of sport participation.The patient should be advised that implants may bend, break or loosen despite restriction in activity.Possible adverse events: bending, disassembly or fracture of implant and components.Loosening of spinal fixation implants may occur due to inadequate initial fixation, latent infection, and/or premature loading, possibly resulting in bone erosion, migration or pain.Postoperative fracture due to trauma, defects or poor bone stock." the root cause of this event cannot be determined.No conclusions can be drawn.
