Manufacturer Narrative

Manufacturing records were checked confirming the batch number involved was manufactured correctly up to specification and in-line with the relevant checks and tests.No manufacturing deviations were reported.No other complaints received on a total of (b)(4) hybrid glenoid manufactured with the same lot#.Available explants pictures + pre-op revision x-rays (no exact date) were received by limacorporate.Following, the medical consultant's opinion on the case, based on the info received: "the preop radiographs show a superiorly decentered humeral head as it might indicate rotator cuff failure which is one of the most common reasons for failure of tsa.The explant shows severe pe wear at the edges which underlines the problem with a decentered head.This can be due to imperfect positioning during the primary implantation, which we don't know for sure and it can be a fateful event as named before.Nevertheless in my opinion this is the reason for the failure and it is not implant related".We will send a final investigation report once the explants (available) will be received.
