Product was returned and examined and the root cause of the failure could not be established.Review of the device history record notes no material non-conformance¿s, no manufacturing errors, nor discrepancies with respect to material type, treatments, dimensions that may have caused or contributed to this mode of failure.Even though root cause could not be confirmed, the fracture of the tap driver was consistent with off-angled and/or excessive force possibly from sclerotic bone.Labeling review: ".Warnings, cautions and precautions: the implantation of pedicle screw spinal systems should be performed only by experienced spinal surgeons with specific training in the use of this pedicle screw spinal system because this is a technically demanding procedure presenting a risk of serious injury to the patient.".
