Manufacturer Narrative

Reported event was confirmed by review of medical records noting liner fracture and dislodgment with some metallosis.Progressive worsening pain and difficulty walking.Mri noted moderate fluid posterior to the hip continuing around the lateral aspect of the greater trochanter.Aspiration of the hip joint showed dark blood negative on culture.Patient has severe pain with range of motion.Patient is experiencing shifting and has a popping sensation although no dislocation.Tissues were very poor quality and poor turgor.A lobulated mass of dark gray tissue was identified.A small amount of fluid in the joint space that was dark and slightly clotted with blood was removed.Cultures and heterotopic tissue were sent to the lab.Inside the capsule was multiple cartilage fragments.The locking mechanism of the shell was bend and flattened.The posterior superior aspect of the cup was somewhat flattened with a small notch in the neck below the trunnion.The stem was found to be well fixed.The gluteus medius and miniumus muscles were very thin but not eroded or damaged by the metallosis reaction.During removal of the cup, some posterior superior bone thinning was noted and a large amount of the anterior posterior column was preserved but there was somewhat of a deficiency posteriorly.Dhr was reviewed and no discrepancies were found.The root cause is unable to be determined.If any further information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.
