It was reported that a patient underwent a right shoulder arthroplasty.Subsequently, humeral component radiolucency was noted at varying times spanning from two (2) days to one (1) year post-operatively.Signs of humeral osteolysis were also noted.The initial surgeon noted there was a gap present between the humeral component and humeral head implant during the initial procedure, due to an issue with a discrepancy between the trial head representation and the definitive humeral head implant.The surgeon states this may be leading to the radiolucency.
