The returned product was confirmed to be fractured.The cable is frayed and fractured completely in two.The product was measured against the print specifications at several dimensions and it was confirmed that all measurements taken were within specification.The device history records were reviewed and the records indicated that the parts met specifications at the time of manufacture.A complaint history search found that this is the first report of any nature for this lot number.The cable is used for treatment.There is a package insert included with this instrument which has instructions for use.Some of the relevant instructions included in this insert are "the amount of tension placed on the cable surgically depends upon the clinical situation and requires judgment by the surgeon.Utmost care should be taken to prevent excessive tensioning of the cable around the bone because overtensioning may damage the bone.And, breakage of the cable may occur by overtensioning when the scale blade reaches full travel, leaving bundles of frayed cable inside the tensioner." due to the condition of the returned cable being frayed and fractured, the most likely cause of the cable breaking is overtensioning.
