Lateral radiographic images of the right and left distal radius fractures, respectively. Red arrows indicate the dorsal metaphyseal spikes caused by the dorsally displaced distal radius fractures.

On plain radiographs, we observed bilateral extra-articular and dorsally displaced distal radius fractures with moderate dorsal angulation and mild radial shortening (Figure 1).
Intraoperative images of the extensor pollicis tendon ruptures. The red arrows indicate the tendon rupture at the musculotendinous junction of the EPL tendon with irregular tendon edges.

No pathological finding that may predispose to rupture was detected in ruptured EPL tendons (Figure 2).
Clinical picture of the patient at 8 weeks after surgical intervention. The patient was nearly pain-free, and the full range of motion was achieved at this time point.

The patient achieved a full range of motion for both wrists and fingers at 8 weeks (Figure 3).
Postoperative radiographs of the left and right wrist of the patient, respectively. The red arrows indicate the mild dorsal cortical spikes on the dorsal cortices of both distal radii. However, the patient had no signs or symptoms related to these spikes since the EIP tendons were transferred through a subcutaneous tunnel.

Hand scores were 10.8 and 11.7 for the right and left hands, respectively. At this time, the dorsal cortical spikes on the distal radius dorsal cortex can still be seen on both wrists via lateral X-ray (Figure 4). However, since the EIP tendons were transferred through a subcutaneous tunnel, and the EPL tendon sheaths were covered with extensor retinaculum flaps, there were no signs or symptoms of irritation on the transferred EIP tendons.
