Product complaint #(b)(4).This report is being submitted pursuant to the provisions of 21 cfr, part 803 (and/or part 4, as applicable).This report may be based on information which has not been investigated or verified prior to the required reporting date.This report does not reflect a conclusion by depuy synthes, or its employees that the report constitutes an admission that the product, depuy synthes, or its employees caused or contributed to the potential event described in this report.Additional narrative: investigation summary the product was returned to depuy synthes for evaluation.Visual inspection of the returned device found the spring deformed.Device had signs of usage on its overall surface and no other anomaly was identified on its surface.The observed condition of the device was consistent with exposure to unintended forces, like usage of excessive force while trialing or by assembling the mating device in a misaligned position.Properly handling and¿attention to the approved use of the device diminishes the risk of failure.As per s-rom® modular hip system surgical technique, page 5 and 17, the next precautions need to be followed during the trial stem insertion using the neck trial: "assemble the trial implant by snapping the chosen neck onto the appropriate size distal stem trial.Align the lateral laser marks in neutral initially and introduce the trial neck and trial stem construct into the femoral canal.The trial neck can be adjusted in 10-degree increments or "clicks" until desired version is obtained.Tighten the trial neck to the trial stem using the nut tightener.Tip: the opposite end of the nut tightener will thread onto the stem trial for extraction, should that be necessary" and "introduce prior to trial reduction".A dimensional inspection was not performed since it was not applicable to the complaint condition.A functional test was unable to be performed due to the post-manufacturing damage and as mating component was not returned for evaluation.The overall complaint was confirmed as the observed condition of the srom neck trl 36 std 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 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 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.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
