Event Description

No further event information at time of this report.

Event Description

It was reported that during an initial left hip arthroplasty, a screw slipped through the hole and emerged past the cage.The screw was able to be removed without incident and was replaced with a competitor's screw which also slipped and remains implanted.Operative notes indicated that the reported device did not cause or contribute to the previously reported patient impact and serious injury.Due diligence is complete as multiple attempts have been made however it was reported that no further information is available.

Manufacturer Narrative

This follow-up report is being submitted to relay additional information.Visual and dimensional evaluations of the product could not be performed as no product was returned nor were pictures provided.Device history record was reviewed and no discrepancies related to the reported event were found.Medical records were provided and reviewed by a health care professional.Review of the available records identified the following: an initial left total hip arthroplasty was performed where 2 6.5mm screws were placed for fixation of a cage.One screw emerged past the cage, and thus was removed and replaced with a competitor's screw that slipped through the cage as well and remains implanted.Radiographs were provided and reviewed by a health care professional.Review of the available records identified the following: left total hip arthroplasty, also with acetabular reconstruction.Lateral most screw along the superior acetabular component may have slipped through the hole but difficult to evaluate on these images.This is likely of no clinical significance.This is likely related to the 8mm competitor's screw that slipped through the hole and remains implanted.This complaint has been confirmed based on the provided medical records.The root cause of the reported issue is attributed to user error, as the screw and cage used together are not compatible.A summary of the investigation was sent to the complainant regarding proper use of the device and authorized combinations.If any further information is found which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.
