Background: Scapholunate (SL) ligament injuries can occur concomitantly with distal radius fractures (DRFs), and the management of acute SL injury in the setting of DRFs remains controversial. The purpose of the study is to identify the radiographic incidence of SL widening in DRF treated with volar plate fixation and to determine the functional outcomes of DRF with concomitant radiographic SL-widening. Methods: One hundred and seventeen patients with DRFs, with and without radiographic SL-widening, and treated with volar locked plating, were prospectively enrolled. No SL ligament repairs or reconstructions were performed in any cases. Patients with DRFs with radiographic criteria for SL widening were compared to those without. Patients were evaluated at 3 months and 1 year postoperatively with Quick Disabilities of the Arm, Shoulder, and Hand and Patient-Rated Wrist Evaluation (PRWE) questionnaires. Results: Thirty-one patients (26.5%) were found to have radiographic evidence of SL widening. Patients with concomitant SL widening had less wrist extension at 3 months (52.4 degrees vs 60.8, P = .034) and at 1 year (64.5 degrees vs 71.8, P = .023). The group with SL widening had greater articular step off at 3 months (0.33 vs 0.06, P = .042), but no difference at 1 year (0.11 vs 0.05, P = .348). There were no differences in wrist flexion, supination, pronation, volar tilt, radial inclination, radial height, ulnar variance, PRWE scores, and Quick Dash scores at 3 months and 1 year. Conclusions: Radiographic SL-widening is a common finding associated with DRFs undergoing surgical repair. There are similar clinical outcomes between those with untreated SL widening compared to those without an SL widening at 1-year postoperatively.
