case_images: Intraoperative photograph after the excision of the proximal part of the proximal and extra phalanx of the ulnar thumb. The white arrow indicates the excised part of the radial thumb, including the distal part of the proximal and extra phalanx and the ulnar 2/3 of the distal phalanx.

case_images: Specifically, the proximal phalanx was osteotomized, and the proximal part of the proximal and extra phalanx of the ulnar thumb, the distal part of the distal and extra phalanx, and the ulnar 1/3 of the distal phalanx of the radial thumb were excised (Figures 5, 6).
case_images: Illustrated diagram showing the excised part and the preserved part. The excised part is colored orange, and the preserved part is colored blue. The red dotted lines indicate the osteotomy line.

case_images: The distal end of the proximal phalanx of the ulnar thumb was subsequently transferred to the proximal part of the proximal phalanx of the radial thumb, and the osteotomy site involving the distal phalanx and metacarpal was fixed longitudinally with a 1.0 mm Kirschner wire (Figure 7).
