Manufacturer Narrative

No device was returned and no radiographs could be provided confirming the alleged complaint.The patient post op activity levels are unknown and it is unknown whether the patient had achieved fusion.While the root cause of the issue is unknown though the patients post operative physical activity, implant selection and hole preparation are believed to be a possible contributing factor.No additional investigation can be completed.Label review: "potential adverse events and complications - as with any major surgical procedures, there are risks involved in orthopedic surgery.Infrequent operative and postoperative complications that may result in the need for additional surgeries." "potential risks identified with the use of this system, which may require additional surgery, include: bending, fracture or loosening of implant component(s)." "the potential for success is increased by the selection of the proper size of the implant.While proper selection can minimize risks, the size and shape of human bones present limitations on the size and strength of implants.Metallic internal fixation devices cannot withstand the activity levels and/or loads equal to those placed on normal, healthy bone.These devices are not designed to withstand the unsupported stress of full weight or load bearing alone." "these devices can break when subjected to the increased load associated with delayed union or nonunion.Internal fixation appliances are load-sharing devices that hold bony structures in alignment until healing occurs.If healing is delayed, or does not occur, the implant may eventually loosen, bend, or break.Loads on the device produced by load bearing and by the patient¿s activity level will dictate the longevity of the implant." "patient education: preoperative instructions to the patient are essential.The patient should be made aware of the limitations of the implant and potential risks of the surgery.The patient should be instructed to limit postoperative activity, as this will reduce the risk of bent, broken or loose implant components.The patient must be made aware that implant components may bend, break or loosen even though restrictions in activity are followed." (b)(4).

Event Description

On (b)(6) 2021 a patient underwent a posterior fixation procedure from t10 to s2ai where the surgery was completed without issue.On (b)(6) 2022 it was reported that the pedicle screw at t10 has backed out and the screw tip was found to be in cranial direction.On (b)(6) 2022 a revision procedure occurred where the screws at both sides t10 were removed and pedicle screws were added at t6-t9, and the rods at t6-t9 were connected to the caudal rods with inline connectors.The patient is doing well post revision.
