X-rays at first visit. A Bado type III Monteggia fracture and fractures of the distal radius and ulna were observed on the same side. (a) AP view of the elbow joint. (b) Oblique view of the elbow joint.

In addition, fractures of the distal radius and ulna, as well as dorsal displacement of the distal fragment, were seen (Figure 1).
X-rays images after manual reduction. (a) AP view of the elbow joint showing subluxation of the radial head. (b) Lateral view of the elbow joint. (c) Front view of the wrist joint showing dislocation of the distal radius. (d) Lateral view of the wrist joint showing dislocation of the distal radius.

However, because it was difficult to maintain the reduction of the radial head, as shown in Figure 2, open reduction and percutaneous procedures were performed under general anesthesia.

Further, open reduction and fixation of the fractured distal radius and ulna were performed with Kirschner wires (Figure 3).
X-rays 3 months after surgery. (a) Front view of the elbow joint. (b) Lateral view of the elbow joint. (c) Front view of the wrist joint. (d) Lateral view of the wrist joint.

Additionally, plain radiographs taken at the same time showed a radially convex curvature at the proximal portion of the ulna and lateral subluxation of the radial head (Figure 4).
Twenty-one years after surgery. (a) Extended elbow. (b) Flexed elbow. (c) Forearm supination. (d) Forearm pronation.

Neither spontaneous pain, pain during exercise, tenderness, nor ROM asymmetry were observed (Figure 5).
X-rays 21 years after surgery. (a) Front view. (b) Lateral view. The compatibility of the radiocapitellar joint was good, and no malunion was observed.

The biocompatibility of the radiocapitellar joint was good, and no malunion was found in the distal radius and ulna (Figure 6).
