Background: Revision rates following radial head arthroplasty (RHA) for unreconstructible fractures (RHFs) differ vastly in the literature, and little is known about risk factors that are associated with revision surgery. The purposes of this study were to assess rate RHA determine factors. Methods: A total 122 patients (mean age, 50.7 years; range, 18 79 years) 123 RHAs who underwent RHFs between 1994 2014 ≥3 years out from surgery included. Demographic variables, injury procedure-related characteristics, radiographic findings, complications, procedures assessed. Cox regression analysis was performed identify RHA. Results: median follow-up cohort 7.3 (interquartile range [IQR], 5.1 10.1 years). All had RHFs: Mason-Johnston type-IV injuries most prevalent (80 [65%]). One or more osseous ligamentous seen 89 elbows (72.4%). time 7 days (IQR, 3 11 days). Implanted prostheses categorized as rigidly fixed (65 [52.8%]) loosely (58 [47.2%]). 28 (22.8%) at a 1.1 0.3 3.8 years), majority (17 [60.7%]) undergoing within first 2 years. common reason painful implant loosening (14 [29.2% 48 complications]). Univariate suggested Workers’ Compensation claims (hazard ratio [HR], 5.48; p < 0.001) use an external fixator (HR, 4.67; = 0.007) significantly Conclusions: high; cause loosening. surgeries predominantly after implantation, surgeons should be aware management elbow Level Evidence: Therapeutic IV .
