[5930594]
Device report from synthes (b)(4) reported an event in denmark as follows: it was reported that the patient was implanted with six bone anchor plates and an unknown quantity of 6 mm self-drilling matrix midface screws on (b)(6) 2014. On an unknown date one of the plates, located in the mandible, broke. It was reported that the head of the plate had broken off. Elastic had been used only for a few days. On (b)(6) 2014, a revision procedure was performed to address the broken plate head so treatment could be continued without removing the plate. The surgeon created a temporary solution by milling the plate to make a hook and attached etched plastic dental material to the broken end of the plate. This enabled treatment, which involves pulling/drawing the plate by elastic, to continue. The plastic attachment had been changed twice during (b)(6) 2014 due to failure. During a follow up exam on (b)(6) 2014, the provisional attachment was determined to be working fine. The other five bone anchor plates are reported to be working correctly with no breakage reported. A related complaint ((b)(4)? Reported separately) addresses the broken plate and the initial procedures performed to address it. A revision/explant surgery was performed on april 30, 2015 to remove the broken anchor plate and associated screws. A new anchor plate was implanted during this surgery. The revision/explant surgery is addressed in this complaint. This report is 1 of 2 for (b)(4)
