Additional information: d6b (explanted date), h6 (component code, type of investigation, investigation findings, investigation conclusions).Results of investigation: the associated device was returned and evaluated.The visual inspection revealed the implant fractured into two pieces.The visual also reveals the ceramic head is still attached to the implant.The clinical/medical investigation concluded that, the provided photos of the explants and x-ray image dated (b)(6) 2023 validates the reported stem breakage.The acetabular cup remains in situ as well as the cemented non s+n insert.The fracture of the stem is likely related to the patient¿s fall as reported.Based on the information provided, there is no evidence of a malperformance of the implant.The impact to the patient is limited to the revision surgery and the associated recovery period.A review of complaint history for the part number over the past 12 months and for the batch number based on historical data of the device did not reveal similar events for the listed device.A review of the instructions for use documents for total hip systems revealed that fracture of the implant can occur as a result of trauma, strenuous activity, improper alignment, or duration of service.A review of the risk management file revealed this failure mode was previously identified.The anticipated risk level is still adequate.A historical review concluded that there are no prior actions related to this product and event.According with inspection procedure, the part configuration should be verified per print.At this time, we have no evidence to conclude that the product failed to meet any specifications at the time of manufacture.Factors that could contribute to the reported event include surgical technique, patient anatomy, abnormal loading of limb, excessive forces and/or traumatic injury.Based on this investigation, the need for corrective action is not indicated.Should additional information be received, the complaint will be reopened.No further investigation is warranted for this complaint; however, we will continue to monitor for future complaints and investigate as necessary.We consider this investigation closed.Corrected data: b5 (narrative), d9&h3 (sample returned for analysis), e4 (reporter did not submit a report to fda), h6 (health effect - clinical code).
