Manufacturer Narrative

(b)(4).This final report is being submitted to relay additional information.Product has been returned to biomet uk ltd for evaluation and forwarded to the complaints processing unit for investigation.It was reported that during surgery, the oxford femoral drill was found not to be in working order.Visual inspection shows some wear/damage to the distal end of the drill and the cutting edges are showing signs of wear.The oxford quick release drill bit 6.35mm (32-422845) is used in conjunction with the femoral drill guide to drill into the femoral condyle bone, this along with the frictional contact with the drill guide will cause wear on the cutting edges, this in turn will cause the drill bit to lose its cutting effectiveness in time.Ref: 1219.3-glbl-en-reusable-instrument-lifespan-manual-digital (page 38).The oxford quick release drill bit 6.35mm (32-422845) was manufactured march 2016 and has most likely been used in many operations.A review of the complaints database shows that we have received 1 reported events for cutting surfaces not sharp for the same item number 32-422845 prior to the reported event.Risk assessment: the severity associated with the above line is 1.This gives a severity score of 1, no patient user or other stakeholder harm as the incident did not delay surgery.The actual severity score is in line with the risk file.Occurrence rate assessment 29 july 2017 to aug 2020.(b)(4) items sold the given period.Complaints history search criteria.Number identified: (b)(4) occurrence ratio: (b)(4) risk score: (b)(4).The severity of the reported event and calculated occurrence for similar complaints are in line with the risk file.The overall score is low risk.No corrective or preventive actions are deemed necessary at this time.If any further information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.
