Manufacturer Narrative

This follow-up report is being submitted to relay additional information.No product was returned or pictures provided; visual and dimensional evaluations could not be performed.Medical records and radiographs were provided and reviewed by a health care professional.Review of the available records identified the following: abnormal alignment (posterior subluxation) of the humeral head with respect to the glenoid.There is suggestion that this could be present on the frontal view as there is possible slightly increased spacing of the glenonhumeral joint without overlapping of the humerus with the acetabulum; however, this can also be technical in nature.Overall fit and bone quality likely normal with exception of periprosthetic lucency surrounding the glenoid screw.The screw may be slightly subluxed deep to the articular surface of the glenoid.No instability found besides the abnormal alignment which could cause the hardware to come into contact and cause noise.Evaluation of rotator cuff arthropathy and rotator cuff tear cannot be performed radiographically; only by mri or ct arthrogram can this be done.In a situation of a massive full thickness rotator cuff tear, there is often loss of the subacromial space; however, this is not seen on this radiograph.Assessment for degenerative joint disease is not an assessment to be made with an arthroplasty, as the joint space has been replaced by hardware.Dhr was reviewed and no discrepancies relevant to the reported event were found.A definitive root cause cannot be determined.If any further information which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.
