WHEN IT CAME OUT THE INNER PIECE WAS BENT AT APPROXIMATELY A 45 DEGREE ANGLE. HE CORRECTED IT WITH THE RATCHETING CLAMP FROM THE EXTRACTION SET. HE THEN ASKED IF WE HAD ANOTHER DEVICE, AFTER WHICH HE TRIED USING THE MWB216 AND MWD148 COMBINATION. THE GLENOSPHERE DISASSOCIATED, BUT AFTER THE PROCEDURE THOSE TWO PIECES WERE STUCK TOGETHER AND THE MWJ130 INNER PORTION WAS NO LONGER TRACKING PROPERLY.

• MalfunctionAug 19, 2021Material Twisted/Bent; Material Twisted/Bent

  IT WAS REPORTED THAT THE SURGEON WAS ATTEMPTING TO TAKE THE SIZE 36 GLENOSPHERE OFF AND UPSIZE DUE TO STABILITY ISSUES THE PATIENT WAS HAVING. AFTER BACKING THE SET SCREW OUT AS FAR AS POSSIBLE THE SCREW CAME TO A POSITIVE STOP AND WOULD NO LONGER SPIN. THE SURGEON USED BOTH THE REVERSE II AND PERFORM REVERSE EXTRACTORS TO ATTEMPT TO REMOVE THE SPHERE BUT HE ENDED UP BREAKING THE FEET OF THE PERFORM REVERSE EXTRACTOR AND BENDING THE REVERSE II EXTRACTOR ATTEMPTING TO REMOVE THE SPHERE. THE SURGEON TRIED TO RE-ADVANCE THE SCREW DOWN JUST TO RESET EVERYTHING BUT WAS UNABLE TO DO SO AS THE SPHERE SCREW WAS STUCK AND WOULD NOT ADVANCE CLOCKWISE NOR COUNTERCLOCKWISE. WE NEEDED TO GO TO A 42 SPHERE TO LATERALIZE THE PATIENT FOR STABILITY BUT WE WERE UNABLE TO DO SO. THE 36 SPHERE IS STILL IN THE PATIENT.

  Patient problems: Failure of Implant

• InjurySep 27, 2016Material Fragmentation; Material Deformation; Material Fragmentation; Material Deformation

  THE TIP OF THE SCREW BROKE OFF AND THEN WAS NOT USED TO REMOVE THE SPHERE. WHEN THE SPHERE WAS EXTRACTED FROM THE PATIENT WE LOOKED INSIDE THE SPHERE FOR THE TIP AND COULD NOT FIND IT. THE SPHERE DID "FLY" OUT OF THE PATIENT, SO THE TIP COULD HAVE FLOWN AND LANDED SOMEWHERE IN THE ROOM. WE DID LOOK ON THE FLOOR AS WELL. GIVEN THIS, THERE IS STILL A CHANCE THAT THE TIP IS INSIDE THE PATIENT.
