Event Description

It was reported that during an arthroplasty procedure, when the surgeon was attempting to screw the spacer (ar-9555-06) into the suturecup, ar-9502f-36cpc, the screw would not advance fully.It would go in for about 3 full screw driver twists, then squeak loudly and seemingly bottom out but remain a few millimeters proud.It was so proud that the surgeon could not fit the poly liner (ar-9503s-03c) in to the spacer.After many tries, different screw drivers and angles the surgeon decided to try a +6 (ar-9503s-06c) liner in fear that the cup was stripped and unable to accept a spacer.Once the +6 was put in and initial reduction and range of motion was carried out the surgeon was not at all satisfied with the fit.The surgeon then decided to try the spacer again, this time a +9 spacer (ar-9555-09).This spacer screwed in properly and perfectly on the first try without resistance.The surgeon used the original +3 poly in the spacer and reduced the shoulder.Further information requested.Additional information provided 02/18/2020: procedure being performed was a revision reverse total shoulder for an original proximal humerus fracture.Specifically a humeral stem change and addition of a spacer.The humeral stem loosened and subsequent dislocation of shoulder.Patient's quality of bone was described as medium to soft.Nothing broke from the implant, the screw just wouldn't fully seat into the cup.The rep ended up opening a +9 spacer that threaded into the cup right away as it was intended to and the surgeon implanted the poly liner and reduced and closed the shoulder.Additional information provided 03/09/2020: the original date of surgery was (b)(6) 2019.The original stem that was implanted was ar-9501-05p lot # 18.01631.
