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 time was prolonged.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.Four needles were returned from lot 108328.Three needles were broken at the eye of the needle.One needle was intact.The broken needles have clamp marks around the needles closest to the eye and point.The unbroken needle does not have any marks on it.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.
