Additional Manufacturer Narrative
Additional information: h6 the reported event could be confirmed as post-op ct scans were provided for investigation.The implant was difficult to place due to a newly formed bone lamella that developed naturally in the two months between design and surgery.Despite the poor fit, the implant met all design standards, and no adverse outcomes occurred apart from a brief surgical delay.In conclusion, the root cause of fitting issue could be attributed to the presence of bone lamella during initial surgery.Based on the investigation, there is no indication for an incorrectly working product or any design, material, or manufacturing-related issue.Therefore, no corrective and/or preventive actions are deemed necessary at this time.
