Manufacturer Narrative

Root cause: the blade is supplied to deroyal by (b)(6).Therefore, a supplier corrective action report (scar) was issued to (b)(6).In its response, (b)(6) stated it did not receive the affected blade or samples from the same lot to test; therefore, it is difficult to determine the root cause of the broken blade.With the information available, a potential root cause could be identified that, if the blade was used in or around the bone, any twisting or excessive lateral pressure could contribute toward the blade breaking.Corrective action: a corrective action was not taken.Investigation summary a medwatch notification was received indicating that a blade broke during a surgical procedure, which caused an injury to the patient requiring intervention.This was entered as an internal complaint (call 51612).A sample was not returned for evaluation.The end user was contacted as to which handle the blade was placed onto before usage.The user responded that the deroyal recommended handle was used for the blade.Five blades were removed from stock on hand for testing.Each blade was placed onto the required handle and used to cut across neoprene foam.The product was acceptable and showed no signs of breakage or damage.The blade is supplied to deroyal by (b)(6).A scar was issued to the supplier, and a response was received november 19 and accepted by deroyal personnel.Using the lot number provided, (b)(6) confirmed they have received no other complaints of this nature for the product.A total of 423,600 carbon sterile sm15 blades were produced and sold for the lot number.The purchase order was reviewed for discrepancies that may have contributed to the reported event.No discrepancies were identified.(b)(6) provides videos online demonstrating how to properly attach each blade to the handle and remove after usage.A total of 469 units have been sold since 2018, and there has been one complaint during that timeframe, yielding a complaint-to-sales ratio of 0.002132.There have been no other complaints similar to this one in nature.The investigation is complete at this time.If new and critical information is received, this report will be updated.
