    ICJR DEBATES: 1-Stage vs. 2-Stage Revision for an Infected Shoulder Arthroplasty

    When a shoulder arthroplasty patient is diagnosed with a periprosthetic joint infection (PJI), surgeons should strongly consider a 1-stage revision, April D. Armstrong, MD, MSc, FRCSC, told attendees at ICJR’s 8th Annual Shoulder Course.

    Compared with a 2-stage revision, a 1-stage revision is associated with reduced patient morbidity, including only 1 exposure to anesthesia, and lower costs for the patient, health system, and third-party payers, Dr. Armstrong said. What’s more, outcomes are similar, with Nelson et al [1] reporting 90% eradication of infection with 1- and 2-stage revisions.

    So, Dr. Armstrong asked, why would a surgeon want to do 2 surgeries when only 1 is needed?

    Because the answer may not be clear-cut, countered John M. Itamura, MD, with multiple factors determining the procedure chosen, such as:

    • Patient age and comorbidities
    • Acute versus chronic infection
    • Infecting organism(s)
    • Number of prior surgeries
    • Type of arthroplasty: anatomic versus reverse

    The indications for 1-stage versus 2-stage are unclear, Garrigues et al [2] concluded. Although data in their systematic review favored 1-stage revision, some selection bias may have occurred. [2] In a systematic review on reverse shoulder arthroplasty, Stone and Namdari [3] postulated that the infecting organism could be the determining factor in the chosen treatment, with 2-stage revision for virulent organisms and 1-stage revision for less-virulent organisms.
