Event Description

An open surgery (on (b)(6) 2022 ) on the spine for c2-c4 fusion was performed with the aid of the display by the brainlab navigation software spine&trauma 3d 1. 5. 1. During the procedure the surgeon: with the patient in prone position, attached the navigation reference clamp and array at c2. Performed the image registration (surface matching) to match the pre-operative ct and display of the navigation to the current patient anatomy, verified the registration and considered it inaccurate. Performed a second image registration, verified and accepted the registration, considering it to be acceptable for the procedure. Placed four screws using aid of navigation. Acquired an x-ray for verification of screw position and detected that the screw(s) placed in c2 deviate from their intended position (by 3-4 mm). Removed the screw(s) from c2. -continued the surgery without aid of navigation (but using fluoroscopy). According to the hospital/surgeon: the pedicle screw(s) not placed as intended with aid of navigation were removed in the very same surgery. There was no actual harm nor negative effect to the patient reported due to the deviating placement no further remedial actions for the patient were reported that would have been done, necessary or planned, nor was prolongation of hospitalization reported.

Manufacturer Narrative

A risk to the patient's health could not be excluded for these specific circumstances, since pedicle screw(s) was/were positioned in the patient's spine in a different position than desired with brainlab navigation involved, although according to the hospital/surgeon: the pedicle screw(s) not placed as intended with aid of navigation were removed in the very same surgery. There was no actual harm nor negative effect to the patient reported due to the deviating placement. No further remedial actions for the patient were reported that would have been done, necessary or planned, nor was prolongation of hospitalization reported. A comprehensive investigation by brainlab regarding this specific event is currently ongoing and final conclusions are pending. Brainlab plans to issue a follow-up report to the fda upon completion of investigation.
