Event Description

It was reported during a procedure on (b)(6) 2020 the tip of a ar-8737-37 (lot: 1391933) broke off in the head of the ar-8730-30h (lot: 10668937) screw.When the breakage occurred, the screw was unable to be fully seated and was left proud.The surgeon removed the screw on (b)(6) 2021 using another manufacturer's removal system.The rep reported there were no arthrex products implanted during the revision surgery.

Manufacturer Narrative

Complaint confirmed.One unpackaged ar-8730-30h screw (no batch indicator provided) was received for investigation.Visual inspection using micro-vu id: 654 identified that the tip of a driver was indeed lodged within the hex of the returned ar-8730-30h.Due to the location of the driver fragment, as well as the warped condition of the hex, the dimensions of the screw hex could not be accurately measured.The threading surrounding the hex was severely stripped and warped.Material analysis testing identified that the screw met design specifications for the material composition.The root cause of the event remains undetermined.However, the most probable cause can be linked to over-engaging the driver within the screw head, alongside the application of excessive force during insertion.
