Event Description

It was reported that, during a revision surgery performed due to the failure of competitor's devices, the screw that allows the swiveling of one (1) lgn offset coupler trial 6mm broke during impaction.This led to the stem being stuck in the femur; however, it was eventually removed after a few attempts.All the pieces were retrieved from the patient using a midas rex and an osteotome.The procedure was resumed, after a non-significant delay, by changing the surgical technique.No injury was reported as a consequence of this issue.

Manufacturer Narrative

H3, h6: the device was not returned for evaluation; therefore, a device analysis could not be performed.However, the photographs were reviewed and revealed that the connection screw is broken and a piece remained threaded inside the female connection component.A review of the production order did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.A review of complaint history based on the historical data revealed a similar event for the listed batch, this failure mode will be monitored for future complaints for any necessary corrective actions.A review of the risk management file 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 product and event.At this time, we have no evidence to conclude that the product failed to meet any specifications at the time of manufacture.This device is a reusable instrument that can be exposed to numerous surgeries.Damage from prolonged use, misuse or rough handling are likely potential factors that could contribute to the reported event.We recommend that all reusable instruments be routinely inspected for wear and damage and replaced as necessary.Based on this investigation, the need for corrective action is not indicated.Should the device 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.
