Revision surgery - due to the cemented modular reverse shoulder prosthesis (rsp) humeral components having aseptically loosened and were causing pain.The original components were removed without much difficulty and a cemented 8mm monoblock stem, +8mm spacer and a +4mm semi - constrained liner were then implanted to the surgeons satisfaction.All of the glenoid components were well fixed and remained.
Additional Manufacturer Narrative
The reason for this revision surgery was device loosening.The previous surgery and the revision detailed in this investigation occurred over 4 years and 9 months apart.The healthcare professional indicated there was no delay in surgery and another suitable device was available for use.The revision surgery was completed as intended.The device was disposed of at the hospital and not made available to djo surgical for examination.A review of the implant device history records (dhr) shows that the reported component used in the previous surgery met design and manufacturing requirements.There were no non-conforming material reports (ncmrs) associated with the suspect medical device that may have contributed to the event.The device was within its expiration date at the time of use during the previous surgery.Customer complaint history of the reported device showed no present trends or on-going issues that are in need of review.There were no findings during this investigation that indicate that the reported device was the source or had a direct connection with the loosening.Root cause of this complaint was a revision surgery due to the loosening.There are many factors that may contribute to the event that are outside the control of djo surgical are loose joints from degenerative tissues, patient bone deterioration, excessive range of motion or trauma.No additional information was submitted with the complaint regarding pre-existing conditions of the patient or any activities that may have contributed to the event and hence a definitive root cause cannot be determined.Inventory containment is not required as there are no indications of a product or process issue affecting implant safety or effectiveness.
