Additional Manufacturer Narrative
Product complaint # (b)(4).Investigation summary: attune distal femoral cutting block.The attune pin was cross threaded and snapped in the cutting block hole.The product was returned to depuy synthes for evaluation.The depuy synthes team conducted a visual inspection of the returned device.Visual analysis of the returned sample revealed that the attune distal fem cut block has a broken unknown fixation pin head lodged inside and cannot be removed.The observed damage is consistent with a combination of over-tightening the attune distal fem cut block while the unknown fixation pin is inserted off axis at the moment of cut.The overall complaint was confirmed as the observed condition of the attune distal fem cut block would contribute to the complained device issue.Based on the investigation findings, the potential cause is traced to unintended user error, and it has been determined that no corrective and/or preventative action is proposed.There is no indication that a design or manufacturing issue has caused the reported complaint condition.As part of depuy synthes quality process, all devices are manufactured, inspected, and released to approved specifications.Additional monitoring for any potential safety signals will be conducted through complaint trending and other post-market safety surveillance activities.Device history lot: the product investigation found no evidence suspecting an error in the manufacturing or material that would be a contributing factor in the reported allegation(s).A manufacturing records evaluation (mre) was not performed.
