Additional Manufacturer Narrative
Product complaint # (b)(4).Investigation summary: according to the information received, ¿attune balancing sizer is faulty.The sizing guide is not sliding over the distractor.It is very tight and will not function properly to allow for sizing and balancing¿.The attune bal sizer distractor (lot.Abc25151) returned to depuy synthes for evaluation.The depuy synthes team conducted a visual inspection of the returned device.Visual analysis revealed that only the the bal sizer distractor handle was returned for evaluation.The subassembly was received disassembled from the mating devices and exhibits an overall worn appearance consistent with heavy and constant usage.Functional testing was performed with the returned mating instruments.The assessment revealed that the bal sizer distractor handle was able to properly assemble within the bal sizer distractor column (lot abb16658r).Once the instrument was fully assembled, it was difficult to slide it into the attune balanced femoral sizer; most likely due to the observed condition of the prongs on the mating instrument.The overall complaint was confirmed.However, there is no indication that a design or manufacturing issue with the bal sizer distractor handle (lot.Abc25151) has caused or contributed to the reported complaint condition.Based on the investigation findings, it has been determined that no corrective and/or preventative action is proposed.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.H11 additional narrative: corrected: h3.
