Mycobacterium tuberculosis infection of a reverse total shoulder arthroplasty: a case report.

We describe the case of a 78-years-old male with dyspnea, inappetence and weight loss over a period of two weeks. The CT scan suggested disseminated tuberculosis and T5-T6 spondylodiscitis. During hospitalization, he developed a left shoulder pain where a reverse total shoulder arthroplasty was implanted 11 years ago. Open debridement and lavage with retention of the implant was performed first and intraveinous antibiotics were administered. 3 months after surgery the patient developed a painful sinus track at the incision site. Resection of the fistula tract, soft tissue debridement and removal of the implants were performed before restarting chemotherapy. As the incidence of reverse total shoulder arthroplasty continues to increase throughout the world, periprosthetic joint infection (PJI) will probably raise as well. Diagnosing and treatment of shoulder PJI with atypical germs remains a challenge and explantation seems to be the safer surgical option to avoid recurrent surgeries on patient with increasing comorbidities.
