Manufacturer Narrative

B5: describe event or problem, d10: device available for evaluation? and h6: medical device problem code.Section h3, h6: the associated device was returned and evaluated.Visual examination confirmed that the silicone pip implant was torn near the flexible hinge and was missing the other half of the implant.The implant was worn.The clinical/medical investigation concluded that, per complaint details, a revision was performed approximately 1 year post implantation due to the silicone pip (ring finger) and mcp (middle and index finger) implant breakages in the left hand.Reportedly, the patient current health status is good; however, it was communicated that the requested clinical documentation was not available.Reportedly, the revision was due to the implant breakages.The patient impact included the reported silicone pip and mcp implant breakages and the revision, but due to the limited information, no further assessment can be rendered.A review of the production order did not reveal a manufacturing abnormality that could have caused or contributed to the reported incident.A review of complaint history for the part number over 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 ascension¿ silicone mcp & pip revealed in warnings that excessive activity of the affected joint, uncorrected or recurrent deformity, incorrect sizing of the implant, inadequate soft tissue or bony support and/or implant malposition may damage the structural integrity of the device and could result in implant fracture.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 the implant and instrumentation manufacturing specification, all implants and instrumentation will be 100% visually inspected.At this time, we have no evidence to conclude that the product failed to meet any specifications at the time of manufacture.Potential root causes or contributing factors include failure of the joint due to hinge fatigue, trauma, incorrect sizing, or improper seating resulting in additional stress on the hinge/implant.The silicone pip implant features a flexible hinge made of molded silicone.Fatigue and eventual failure of the silicone hinge is a known failure mode of the spip device.To mitigate this risk, the hinge is molded to rest at a pre-flexed angle which results in less strain on the implant and can extend fatigue life.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.
