Event Description

On the pmcf titled dca-1000 accord ss clinical dataset, it was reported that, after undergoing right tha, one (1) patient experienced unspecified events that led to a subsequent revision surgery combined with internal fixation on (b)(6) 2021, in which an accord cable system was implanted.The patient suffered an intraoperative acute periprosthetic fracture involving the medial femoral component.The fracture fragment was displaced medially approximately 7 mm.On the lateral view, it was observed that the fracture may extend to the greater trochanteric region.A post-operative follow-up determined a well-healed wound with no evidence of subsidence, loosening, or complicating features.

Manufacturer Narrative

Given the nature of the alleged incident, the devices, could not be returned for evaluation.The clinical/medical investigation concluded that, the provided clinical dataset was reviewed; however, as of the date of this medical investigation, patient-specific supporting clinical documentation has not been provided; therefore, there were no clinical factors found which would have contributed to the event.The patient impact beyond the reported events cannot be determined with the information provided.No further clinical assessment is warranted at this time.A review of the production orders did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.For the oxinium modular head, a review of complaint history revealed a similar event for the listed device over the previous 12 months, but no similar events for the batch based on the historical data, this failure mode will be monitored for future complaints for any necessary corrective actions.For the titanium modular head and the redapt stem, a review of complaint history for the part numbers over the past 12 months and for the batch numbers based on historical data of the device did not reveal similar events for the listed devices.A review of the instructions for use documents for total hip systems revealed in warnings and precautions that congenital deformity, improper implant selection, improper broaching or reaming, osteoporosis, bone defects due to misdirected reaming, trauma, improper implant alignment or placement can increase the risk of femoral or pelvic fractures.Also, failure to use the optimum-sized component may result in fracture of the bone.A review of the risk management files 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 these products and event.At this time, we have no reason to suspect that the products failed to meet any specifications at the time of manufacture.Factors that could contribute to the reported event include patient bone quality, patient condition and/or surgical technique.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.
