This mdr report is based on the reclassification of a previously reviewed complaint.Followup information provided by the user: the user was treating a traumatic ulna fracture in a cancer patient.A small awl was used to create an entry hole for either a 9 or 11mm balloon.Then the 4.5mm burr was used to ream the canal and was broken during use.Then the 5.5mm burr was used to ream the canal and got temporarily stuck in the patient and was broken at the time of extraction.All pieces of both instruments were able to be removed from the patient.The user did not feel the burr guide was necessary for use during this case and did not use it.The user successfully implanted the illuminoss implant in the ulna with great cortical wall contact.The patient outcome was good.Records review: a review of manufacturing records was performed, and found that the devices met specification at the time of manufacture and release.Returned product evaluation: product was received on february 9, 2022.Device decontamination and photo-imaging was performed.The product evaluation performed identified that the break patterns observed are consistent with overtorquing of the device during use.Conclusion: existing evidence supports that over-torquing of the device is the probable cause of this event, although this cannot be definitely proven with the evidence available to the firm at this time.
