Fig. 6. Scatterplot shows the relationships between the method of surgical treatment, maximum ulnar bow (MUB), and the distance of the MUB from the distal end of the ulna. Open reduction alone was successful in four cases (solid circle) in which the MUB was less than 4 mm and the MUB was in the distal 40% of the ulna. Additionally, one case with isolated radial head dislocation was successfully treated with open reduction alone.
