Head-to-neck screw fixation and radial head arthroplasty result in similar postoperative outcomes for low-comminuted radial head fractures with neck involvement.

Background: Fixation of radial head fractures with neck involvement presents challenges. It remains unclear whether the outcomes of head-to-neck screw fixation are similar to those of arthroplasty in this scenario. We conducted a retrospective cohort study to evaluate the clinical outcomes of these two methods for treating such fractures.
