Introduction: Objectives: 1) to evaluate the subjective outcomes in skeletally immature patients undergoing surgical treatment of displaced radial neck fractures, 2) to compare the performance between PROMIS and QuickDash, 3) to evaluate the floor/ceiling effects of the outcome measurements. We hypothesized that the PROMIS scale would correlate favorably with QuickDash and would demonstrate lower floor or ceiling effects. Materials and Methods: Demographic data, associated lesions, fracture type, surgical technique, and complications were evaluated. QuickDash and PROMIS scales (PROMIS Upper Extremity (UE), PROMIS Strength and PROMIS Pain interference) were used for functional assessment. The Shapiro-Wilk test was used to analyze the normal distribution of the data. Metrics correlations were made with Spearman's rho coefficient. Ceiling and floor effects were further assessed. The alpha value was set at 0.05. Results: 26 patients were evaluated. Average age: 7.5 years; average follow-up: 31 months. There were significant correlations between the postoperative QuickDash and PROMIS UE metrics (rs = -0.64, p = 0.003). We found no correlation between PROMIS Pain and PROMIS Strength with QuickDash (rs = 0.001, p = 0.966 and rs = -0.39, p = 0.101 respectively). Ceiling or floor effects were observed at all scales. Conclusion: We observed a strong correlation between PROMIS UE and QuickDash assessing the results after surgical treatment of radial neck fractures in children. However, all the measures had evident floor/ceiling effects, probably due to the size of the cohort and the fact that a high percentage of these fractures usually present favorable clinical outcomes.
