Inadequate fixation of bicolumn distal humeral fractures can result in postoperative complications, including nonunion and contracture. Fixation using medial-lateral parallel plating provides stable fixation and permits an early and intensive program of elbow motion that is associated with a high rate of union. Parallel plate fixation locks the two columns of the distal humerus together and provides the features and stability of an arch. This construct applies an architectural concept and engineering principles to orthopaedicsurgery.
