Aspen surgical performed a follow-up with the customer.The actual device was determined to be available for evaluation.The manufacturing lot number was also provided for review.The end user indicated that during a shoulder surgery, the eye section of the needle separated from the needle.Using x-ray guidance the surgeon was able to located and retrieve the detached eye section of the needle.Surgery was prolonged to retrieve the broken section of needle.The patient tolerated well and follow up care was not required.Analysis result of the finished good lot number and incoming inspections of the raw material were reviewed.All samples passed acceptance criteria.No non-conformance's were noted in the dhr.Two needles were returned from lot 144680.One needle was broken at the tip of the eye.The other needle was intact.The unbroken needle had clamping marks around the needle towards the middle section of the needle and down towards the point.The broken needle had clamping marks that were very close to the point of the needle.According to aspen surgical's ifu, the needles should not be clamped directly on the eye of the needle to the point and should be applied to the flat portion of the needle about 1/4 of the needle length from the eye end.A review of the samples returned show that the needles were clamped improperly either not on the flat side or too close to the eye or point, which likely caused them to break.Based on this information, the root cause is attributed to customer misuse and no further action is required.
