Event Description

Device report from synthes reports an event in (b)(6) as follows: it was reported that on (b)(6) 2020, the surgeons were revising a previous surgery that had developed pjk and showed signs of iliac screw failure.The patient's initial fusion (performed on (b)(6) 2019) was from t11-ilium, with expedium 5.5 and cortical fix implants placed from t11-l5, and nuvasive reline iliac bolts placed for the s2 sai screws (8.5 x 80mm screws).On (b)(6) 2020, the surgeon removed the nuvasive iliac bolts (from the patient's right side) and intended to implant dss viper sai iliac screws (1797-04-xxx).He used a viper 9.0 tap (2797-04-900) and the surgeon proceeded to pass a 10mm sai tap (2797-04-100) down through the prepared pathway, and he requested a 11x80mm iliac screw and proceeded to implant the 1797-12-280 screw.As the screw advanced through the prior pathway, he felt the screw was not advancing through the bone.At this time, he attempted to remove the iliac bolt from the bone but was unable to advance the screw in either direction (clockwise or counterclockwise).In this process, the polyaxial screw head broke from the iliac bolt and was removed from the patient.Attempted to remove the broken screw from the pelvis with the reverse conical extraction drivers from the universal removal set (srb) but could not fit the largest extraction driver over the 11mm screw.The surgeons were satisfied that the implant was not causing additional harm and elected not to continue to attempt to remove the broken screw.The shaft of the screw remains implanted in the patient.They continued with the procedure and placed new sai screws (medtronic) adjacent to the broken screw on the patient's right side.Fragments were generated and easily removed.There was a surgical delay of 60 minutes.Patient status is unknown.The procedure was successfully completed.This complaint involves four (4) devices.This is report 1 of 3 for (b)(4).Related product complaint: (b)(4).
