Manufacturer Narrative

Visual, dimensional, material and functional analysis could not be performed as the device was not returned because it remains implanted in the patient.However, x rays provided show both tritanium cages migrated in the disc space.Device and complaint history records were reviewed and no relevant manufacturing issues or similar complaints were identified as all units met stryker specifications.From the tritanium pl surgical technique: the tritanium pl cages are to be used with supplemental fixation that is intended for use in the lumbosacral spine.If pedicle screws were not inserted earlier in the procedure, insert pedicle screws at this point or other appropriate supplemental fixation.Compression of the pedicle screws or interspinous device may be used to create segmental lordosis of the segment fused.Early loosening may result from inadequate initial fixation, latent infection, premature loading of the device or trauma.Contraindications: any abnormality present which affects the normal process of bone remodeling including, but not limited to, severe osteoporosis involving the spine, as the device was not returned, a definite root cause cannot be determined.Based on the information provided, the most likely cause is the patient's bone condition affected the supplemental fixation.Failure of the supplemental fixation could cause the cage to migrate out of position.

Event Description

It was reported that two tritanium pl cages migrated post-operatively.The patient is asymptomatic, therefore no revision surgery has been scheduled.This report represents the first of the two cages.
