The purpose of this investigation is to evaluate the reported issue of tip fracture.Visual inspection of the imaging provided supports the reported issue that the tip of the k-wire fractured in the patient.Functional inspection was unable to be completed because the part was not returned.Based on the details provided, a l4-5 mis tlif was completed on (b)(6) 2025.Screws were placed at l4 and l5, and an interbody cage was placed in the l4-5 disc space.During the surgery, the tip of the left l5 k-wire broke in the vertebral body and was left in the patient.Due to the inability to replicate surgical conditions and forces experienced by the patient post-op, the exact cause of the failure cannot be determined.The calculated observed risk level matches the expected risk level; therefore, the overall risk of the system has been maintained and there is no further investigation required.
