Event or Problem Description
It was reported that, after a thr surgery, with dual mobility (or3o) implants, was performed on (b)(6) 2025, the patient came back for follow up with a head dislocation.This adverse event was treated with a revision surgery on (b)(6) 2025 in which the oxinium fem hd 12/14 22 mm +4 and the or3o dm xlpe insert 22/38 were exchanged.Also, when opening the wound it was found that there was corrosion on the oxinium fem hd 12/14 22 mm +4.The current health status of the patient is unknown.
Additional Manufacturer Narrative
The devices were not returned for evaluation.However, the photographs were reviewed, and revealed that the femoral head is deformed.The clinical/medical investigation concluded that imaging and surgical findings revealed corrosion and deformation of the oxinium femoral head, likely due to impingement, dislocation, or removal.While the exact cause remains unclear¿due to limited imaging and unknown patient adherence to post-op care¿a component malfunction was not confirmed.The patient underwent revision surgery, and although the full impact is unknown, a temporary recovery period is expected.A review of the production orders did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.For the femoral head, liner, acetabular shell and stem, a review of complaint history for the part number over the past 12 months and for the batch number based on historical data of the device did not reveal similar events for the listed device.For the insert, a review of complaint history revealed a similar event for the listed part number over the previous 12 months, but no similar events for the batch based on the historical data, this failure mode will be monitored for future complaints for any necessary corrective actions.A review of the instructions for use documents for total hip systems revealed that postoperative warnings and precautions highlight the need of warning patients against unassisted activity, particularly use of toilet facilities and other activities that require excessive motion of the hip, as they may result in subluxation or dislocation.Besides, for preoperative warnings and precautions oxinium oxidized zirconium femoral heads should never articulate against metal bearing surfaces because severe wear of the metal bearing surfaces may occur.A review of the risk management files revealed this failure mode was previously identified.The anticipated risk level is still adequate.A historical review concluded that there are no prior actions related to this products and event.At this time, we have no evidence to conclude that the products failed to meet any specifications at the time of manufacture.Factors that could contribute to the reported event include injury, patient condition, postoperative care, size selected or abnormal loading of limb.Based on this investigation, the need for corrective action is not indicated.Should the devices or additional information be received, the complaint will be reopened.No further investigation is warranted for this complaint; however, we will continue to monitor for future complaints and investigate as necessary.We consider this investigation closed.
