Cuti- bacterium infection TSR

Hello,
Writing for my husband. He had a TSR in March of 2021 which post operative was never out of pain and it only worsening. Finally in November of 2024 surgeon removed the prostheses and put in a Reverse Shoulder. The biopsy and pathology reports came back showing chronic end stage inflammation in the joint, osteomyelitis of the bone, and this Cuti- bacterium. If anyone out there has dealt with this I would love to hear about the pain you may have had. My husband pain is worsening again to the point where he can’t even use his arm to wipe the kitchen counter. His pain is in the anterior shoulder with severe tenderness/ pain around the incision. Seems so odd to be caused from the infection. Please share any info you may have. We are so beside ourselves here has lost his quality of life at 63 yrs old. Thank you
