PurposeThe objective was to assess the ability of the volar locking plate to maintain the radiographic parameters over the time in elderly patients with complex intra-articular distal radius fractures.MethodsProspective cohort of 66 consecutive patients with mean age of 68 (range 60-81) years and AO type C fractures treated with volar locking plate. Radiographic measurements were performed pre and post-operatively at each follow-up. Clinical assessment was made by Patient-Rated Wrist Evaluation scores, Disabilities of the Arm, Shoulder and Hand score, range of motion, and grip strength.ResultsThe mean post-operative follow-up was 31 (range, 24-47) months. The most difficult parameters to restore intra-operatively were volar tilt and radial height, while radial inclination and ulnar variance were restored in a high rate of patients. There was significant loss of reduction within four post-operative months in volar tilt (p = 0.001) and radial height (p = 0.029). Mean radiographic parameters had no changes from four months to final evaluation. At final follow-up, 50.1% of the patients had all radiographic parameters restored in comparison with the noninvolved wrist, but 83.3% had all radiographic parameters within a functional range (p = 0.001). No significant relationship between radiographic and functional outcomes was found (p = 0.474).ConclusionsThis study found that volar locking plate fixation for displaced intra-articular distal radius fractures in elderly patients was an effective procedure to obtain success functional outcomes. Although reduction loss in volar tilt and radial height occurred within four first months, volar plate was able to maintain fracture stabilization with radiographic parameters within functional range over the time in most patients of these elderly patients.
