Reported event: an event regarding crack/fracture involving a dall miles cable was reported.The event was confirmed through material analysis evaluation of the returned device.Method & results: product evaluation and results: the dall miles cable was returned for evaluation.The strands of the cable appear fractured.Material evaluation was completed and indicated the following comments: the dall miles cable was returned with fractured strands, the cable was examined with the aid of a scanning electron microscope.The fracture is consistent with an overload fracture as indicated by the dimple fracture morphology.Energy dispersive spectroscopy was performed on the fractured component and confirmed it was consistent with a astm f90 alloy (co-cr-w-ni-mn), which is consistent with the drawing.Based on the given information no materials or manufacturing discrepancies were observed on the surfaces examined.Medical records received and evaluation: no medical records were received for review with a clinical consultant.Product history review: a review of the device manufacturing records indicate that all devices accepted into final stock were free from discrepancies.Complaint history review: there have been no other similar events for the lot referenced.Conclusion: the dall miles cable was returned for evaluation.The strands of the cable appear fractured.Material evaluation was completed and indicated the following comments: the dall miles cable was returned with fractured strands, the cable was examined with the aid of a scanning electron microscope.The fracture is consistent with an overload fracture as indicated by the dimple fracture morphology.Energy dispersive spectroscopy was performed on the fractured component and confirmed it was consistent with a astm f90 alloy (co-cr-w-ni-mn), which is consistent with the drawing.Based on the given information no materials or manufacturing discrepancies were observed on the surfaces examined.No further investigation for this event is required at this time.If additional information becomes available to indicate further evaluation is warranted, this record will be reopened.
