Core Tip
Core Tip: This retrospective cohort study compares two consecutive treatment protocols for two-stage hip revision in periprosthetic joint infection: One using only Girdlestone and another incorporating custom-made articulating spacers (CUMARS) whenever possible, or a Girdlestone when necessary. While infection eradication rates were similar, the introduction of CUMARS was associated with shorter hospital stays, earlier mobilization, and more frequent discharge to home. These results suggest that CUMARS facilitates a faster recovery for suitable patients and reduce healthcare burden without compromising infection control, making them a valuable addition to the treatment algorithm. For patients with contraindications, a Girdlestone remains a viable option.
