There are numerous metaphyseal-epiphyseal branches arise within the pronator quadratus and the anterior interosseous artery and course towards the distal radius. These branches may be fundamental to the healing of the distal radius fractures and make nonunion a rare complication. The aim of this study is the evaluation of the role of the pronator quadratus muscle and its repair in volar approach in distal radius fractures treated with plate fixation.
