Event Description

Device report from malaysia reports an event as follows: it was reported that during the final step of a scoliosis surgery on (b)(6) 2023, the surgeon input the crosslinks.Upon the final tightening of the crosslinks nuts, the tip of the instrument shaft attached to the torque limiter handle broke off.The fragment of the instrument shaft was stuck inside the crosslink nut recess.As the implant would be very difficult to remove in any future surgery, the surgeon decided to change the crosslink for this patient.Before implanting it in, the surgeon tested the final tightening mechanism outside of the patient's body.The result was that the other instrument shaft also broke off at the tip.Procedure was completed successfully with a twenty minute delay.There was no patient consequence.This report is for a rod, 480 mm.This is report 4 of 7 for (b)(4).
