Radial Head Replacement for Acute Radial Head Fractures: Outcome and Survival of Three Implant Designs With and Without Cement Fixation.

Although there was a clear trend for worse long-term survivorship with a grit-blasted curved stem, with a HR of 4.6 in reference to the Anatomic Acumed implant, with the numbers available, differences in survivorship did not reach statistical significance based on either implant design or cemented versus cementless fixation.

The differences in survivorship between the 3 implants did not reach statistical significance, but the nonanatomic design with a grit-blasted ingrowth curved stem had a hazard ratio of 4.6 (95% CI = 0.9%–23%) for failure.
