Short summary
We retrospectively compared outcomes of two-stage revision with three common spacer types. No significant difference in failure rate was seen across groups, contributing evidence of similar efficacy. Articulating spacers showed a greater range of motion than static spacers, and static spacers were associated with a higher adverse event rate, directly showing potential advantages and disadvantages of each variant. A trend toward a longer interstage duration for prosthetic spacers may reflect greater functionality.
