Volar Locking Plate Fixations for Displaced Distal Radius Fractures: An Evaluation of Functional and Radiographic Outcomes

Abstract

Objectives: In this study, our aim was to evaluate the functional, radiological and clinical results of the patients which treated with a volar anatomical locking plate due to distal radius fractures retrospectively. Methods: Patients operated with distal radius fracture between 2014-2016 were screened retrospectively. Fractures were classified according to the AO classification. Radiological values for radial height, radial inclination, radial volar tilt and ulnar variance were measured according to the radiological key points described by Medoff. The Stewart scoring form was used to evaluate the radiological results. Flexion-extension, pronation-supination was measured using with a goniometer. Grip strength was measured using a hand dynamometer. Clinical results were evaluated according to the Mayo wrist system. Results: The average age of 60 patients included in this study was 45 and average follow-up period was 13 month. Mean grip strength value was 18.33, the contralateral side was 25.33. The distribution of the Stewart radiological assessment score were 16 (27%) patients excellent, 36 (60%) good, and 8 (13%) moderate results. When evaluated clinically with the Mayo wrist score, the results were excellent in 20 (33%) patients, good in 35 (58%) patients, and moderate in 5 (9%) patients. Statistically significant differences were found in all radiological parameters. (p < 0.05) Conclusion: Surgery using a volar anatomical locking plate is an effective treatment method for distal radius fractures. Joint range of motion can be achieved early with correct fixation of the plate and by beginning joint movement as soon as possible.
