Abstract

Objective: To describe the clinical characteristics of pediatric patients with Wassel type IV thumb duplication who underwent surgery between 2022 and 2024, and to evaluate the surgical outcomes of reconstruction for Wassel type IV duplicated thumbs at the Vietnam National Children’s Hospital. Subjects and Methods: A cross-sectional descriptive study (combining retrospective and prospective data collection) was conducted on 38 patients diagnosed with Wassel type IV thumb duplication who underwent reconstructive surgery at the Vietnam National Children’s Hospital from November 2022 to December 2024. Postoperative outcomes were assessed using the modified Tada scoring system revised by Yin Chun Tien. Results: Among 38 patients, 65.8% underwent surgery between 6 and 24 months of age; 55% were male, and the left hand was more frequently affected (63.2%). The Wassel type IV-b deformity accounted for 60.5% and type IV-d for 10.5% of cases. Postoperatively, 89.5% achieved good results, 10.5% fair, and none poor. No major postoperative complications were recorded. Conclusion: Reconstructive surgery for Wassel type IV thumb duplication, when appropriately indicated and properly performed, yields favorable functional and aesthetic outcomes with a low complication rate.
