Early Radiographic Union Score for Hip Is Predictive of Femoral Neck Fracture Complications Within 2 Years
Objectives:
To determine if the Radiographic Union Score for Hip (RUSH) measured at 3 and 6 months after femoral neck fracture were predictive of reoperation for infection, nonunion, delayed union, avascular necrosis, or implant failure within 24 months of initial surgery.
Design:
Secondary analysis of a randomized controlled trial. Logistic regression was performed to investigate associations between lower RUSH and reoperation. Results were reported as odds ratios (OR), 95% confidence intervals (CIs), and associated P values. All tests were 2 tailed with alpha = 0.05.
Setting:
Eighty-one clinical sites across 8 countries.
Patients/Participants:
Data from 734 of the clinical trial participants with radiographs at 3 and 6 months after fracture fixation were included.
Intervention:
A reviewer blinded to patients' outcomes independently assigned a RUSH at each follow-up time point.
Main Outcome Measures:
Revision surgery rate related to intervention.
Results:
Lower RUSH at 3 and 6 months were associated with increased odds of reoperation within 24 months of fracture fixation. For every 2-point decrease in RUSH at 3 months, there was a 16% increase in the odds of a patient experiencing a re-operation (OR, 1.16; 95% CI, 1.10–1.22; P
