Additional Manufacturer Narrative
Product complaint # (b)(4).Investigation summary: according with information received, it was reported that liner was impacted then dislodged during trailing.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 device found that the altrx +4 neut 36idx52od has the rim and two of the anti-rotation device (ard) tabs deformed.Additionally, the liner presents slightly scratches which are consistent with implantation attempts.Based on the damage observed on two of the ard tabs, it is reasonable to confirm the reported event, as damage in the locking system may prevent the device to be assembled/function as intended.Potential cause can be traced to a component failure caused by assembling the device in a misaligned position or by impacting the implant before it was fully seated.Properly handling and attention to the approved use of the device diminishes the risk of failure.As per pinnacle surgical technique depuy synthes joint reconstruction, page 17 and 18, the following precautions need to be followed: 1) prior to inserting the final acetabular liner, thoroughly irrigate and clean the cup to ensure the locking groove it is clear of any debris; 2) remove all soft tissue from the face of the cup so as not to impede liner seating; 3) an apex hole plug may be used prior to liner insertion; 4) prior to insertion/impaction, mate the liner anti-rotational device (ard) tabs with the ard scallops on the cup; 5) seat the liner using the id impactor that corresponds to the selected implant; 6) because the locking mechanism is tapered, it is important to impact the liner directly into the cup with multiple medium blows, as impacting the liner in a tilted position may prevent complete seating; 7) seating of the liner is visually confirmed when the liner ards are flush with the face of the acetabular cup; however, the liner face will remain proud in relation to the cup face by approximately 1 mm for a neutral liner to 4 mm for a lateralized liner.A dimensional inspection was unable to be performed due to the post-manufacturing damage.A functional test was unable to be performed due to the post-manufacturing damage and as mating component was not returned for the appropriate testing.The overall complaint was confirmed as the observed condition of the altrx +4 neut 36idx52od would have contributed to the complained device issue.Based on the investigation findings, it has been determined that no corrective and/or preventative action is required.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: a manufacturing record evaluation was performed for the finished device product description: altrx +4 neut 36idx52od product code: 122136452 lot number: m51n24, and no non-conformances nor manufacturing irregularities were identified.Corrected: h3.
