Event Description

A patient underwent a posterior lumbar fusion surgery at l3, l4, and l5 in (b)(6) 2017.An extension surgery took place in (b)(6) 2019 at t11-l5 and in (b)(6) 2020 at t11-s2a1 both using another manufacturers product.On (b)(6) 2021, a revision surgery was conducted to replace the implant.The surgeon used the head positioner to remove the screw because the screw head was locked.Once the screw was removed, it was found to have fractured, and the tip remained in the patient's vertebral body.The surgeon suggested the screw shank may have fractured prior to the revision surgery since there was no over-load during the removal process.The tip will be removed during a future revision surgery.No patient injury reported.
