Sequential Radiographic Evaluation During Closed Treatment of Distal Radius Fracture
OBJECTIVES: To test the null hypothesis that there is no significant change in radiographic parameters, which determines an acceptable reduction, beyond 3 weeks in distal radius fractures with closed treatment. DESIGN: Retrospective review of a prospectively gathered registry of distal radius fractu...

Strauch Melvin P. Rosenwasser Columbia University Irving Medical Center Mahidol University Medicine OBJECTIVES: To test the null hypothesis that there is no significant change in radiographic parameters, which determines an acceptable reduction, beyond 3 weeks in distal radius fractures with closed treatment. DESIGN: Retrospective review of a prospectively gathered registry of distal radius fractures. SETTING: Academic medical center. PATIENTS: Patients who underwent closed treatment of distal radius fracture. INTERVENTION: Sequential radiographic evaluation. MAIN OUTCOME MEASUREMENTS: Change of radiographic measurement including radial inclination, radial height, ulnar variance, articular tilt, teardrop angle, anteroposterior distance, intra-articular gap, and step-off. We compared postreduction radiographic parameters once within 2 weeks, at the third week, at cessation of immobilization, and analyzed the interobserver reliability test. RESULTS: There was a statistically significant difference between radiographic measurements, which determined an acceptable reduction between radiographs performed within 2 weeks versus the third week. Radial inclination and ulnar variance were statistically different at the third week compared with the time of cessation of immobilization. Seventy-seven percent of patients who had an acceptable reduction after 2 weeks maintained acceptable alignment at cessation of immobilization. Eighty-five percent of patients with acceptable reduction after 3 weeks maintained acceptable alignment at cessation of immobilization. Radial shortening >1.8 mm at the third week predicts an unacceptable radiographic outcome at cessation of immobilization (sensitivity 94.5% and specificity 90%). CONCLUSION: Radiographic parameters that determine acceptable reduction for closed treatment of distal radius fractures change minimally after 3-week postacceptable closed reduction. Radial shortening at the third week can be used to predict an unacceptable radiographic outcome. LEVEL OF EVIDENCE: Prognostic Level IV.
