Additional Manufacturer Narrative
The reported event could not be confirmed since no functional issue could be detected with the returned reamers.The device inspection revealed the following: one 20mm and one 22mm convex surfacing reamer were returned for evaluation.Both items are in a used condition with slight signs of wear, at first glance the cutting edges of both items are fine.Both devices do not have the color coding (orange for 20mm and red for 22mm) which is part of the design since the year 2011, which shows that both devices are older than 14 years.The inspection of the 22mm reamer has shown that there is a damage visible at the upper part of all four cutting edges.The microscopic inspection has shown that the cutting edges are slightly flattened and discolored in this area, this damage is an indication for a potential metallic contact with higher heat generation, which explains the discoloration.The cutting performance of the 22mm compared with the 20mm reamer was reduced but still acceptable.The reduced cutting performance is also indicated by the different shape of the shavings and can be traced back to the observed damage at the cutting edges.However, all in all it can be stated that the reamer is still functional.The complaint history was reviewed for the reported catalog numbers of the returned parts and apart from pi (b)(4) are no other complaints in relation to worn/blunt devices registered for the affected catalog numbers.Pi (b)(4) was the follow up complaint from the same hospital, where their remaining reamers were returned as they were potentially blunt, the complaint was rated as unconfirmed.A review of the labeling did not indicate any abnormalities.No indications of material, manufacturing or design related problems were found during the investigation.No product related issue could be detected, the root cause of the reported event could not be defined as the returned 22mm reamer is functional as required.The observed damage at the cutting edges is an indication for a contact with a hard object during use but based on the provided information it cannot be defined if this damage is related to the reported event or a previous procedure.If more information is provided, the case will be reassessed.
