Failed total shoulder revised to a ream and run

Sixteen years ago an active man in his 70s presented with right shoulder arthritis


He had a total shoulder with a Hylamer glenoid (now discontinued because of degradation when radiated in air)


This total shoulder served him well for seven years at which time he had some increasing discomfort in his arm and these x-rays showing humeral subsidence and glenoid component wear.



He chose not to have additional surgery until 13 years after his index procedure at which time there was additional subsidence and glenoid deterioration.





He had a single stage revision to a ream and run with exchange of the humeral component. His cultures from surgery were strongly positive for Cutibacterium. He was placed on the red protocol with 6 weeks of IV antibiotics and 6 months of orals. 

His immediate postoperative films are shown below


Three years after his revision he returned for surgery on his opposite shoulder. He scored his right shoulder as 10 out of 12 on the Simple Shoulder Test. His three year post revision x-rays are shown below.



Comment: This is an instructive case illustrating delayed presentation of loosening associated with glenoid component failure and large amounts of Cutibacterium. A single stage revision without reimplantation of a glenoid component has served him well.
