Revision surgery was performed on (b)(6) 2025 due to loosening.Patient received a reverse total should arthroplasty with smr stem, reverse humeral body (pn 1352.15.010), reverse liner std (pn 1360.50.810), 36mm glenosphere with connector (1374.09.105) and smr metal back baseplate (pn 1375.15.605) at an unknown date prior to 2020.Records could not be found of original implants.Due to osteolysis around the baseplate, possibly due to mal-positioned baseplate or notching, the glenoid construct was deemed unstable and loose.Upon revision, above mentioned components, with exception of the humeral stem, were easily removed.An anatomic humeral body trauma medium (pn 1350.15.010) and humeral head dia42mm (pn 1322.09.420) were implanted with eccentrical adaptor taper 2mm long (pn 1331.15.272), and the bone loss on glenoid was filled with bone graft for a potential second stage revision surgery to implant a reverse baseplate.Surgery was completed as intended.Patient is female, date of (b)(6) 1944.The event occurred in the united states.
