INTRODUCTION: Displaced scaphoid fractures warrant surgical fixation to mitigate the risk of nonunion or malunion. We hypothesized that two-screw fixation would result in higher rates of union at shorter times. METHODS: We retrospectively reviewed data of patients who presented with scaphoid fractures and underwent surgical fixation between 1 January 2013 and 30 November 2024. Patients were propensity score matched using demographics and Herbert classification as covariates. RESULTS: < 0.001 for both). Patients in the one-screw cohort showed significant improvements in Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference (PI) and Physical Function scores after surgery as compared with before surgery. The PROMIS PI scores in the two-screw cohort also showed significant differences after and before surgery. Rates of nonunion, time to union and hardware complications did not show statistically significant differences between the one- and two-screw cohorts. CONCLUSION: In this study, we reject our hypothesis as two screws were similar to one-screw fixation for rates of healing and outcomes. LEVEL OF EVIDENCE: III, case-control study.
