About

The purpose of this study is to evaluate the functional and aesthetic outcomes in children with Wassel IV thumb duplication

Full description

Wassel IV thumb duplication is a congenital hand anomaly characterized by the presence of two adjacent thumbs. This condition has significant functional and aesthetic implications.

Previous studies have highlighted the complexity of the surgical management of Wassel IV thumb duplication, underscoring the need for an individualized approach for each case. Early interventions are often recommended to optimize long-term functional and aesthetic outcomes.

The field of study for evaluating these outcomes focuses on the analysis of the medium and long-term consequences of surgical interventions in children with this malformation. Evaluation criteria may include hand functionality, thumb mobility, overall aesthetics, and other aspects relevant to the quality of life of the affected pediatric patients. This medium and long-term approach offers crucial insights for refining treatment protocols and improving the overall management of this condition.

Wassel IV Thumb Duplication Cases

Description:

This group consists of pediatric patients who have undergone surgical correction for Wassel IV thumb duplication. All participants have had a minimum of one year post-operative follow-up. This cohort will be assessed for functional and aesthetic outcomes using the Japanese Society for Surgery of the Hand (JSSH) scoring method. This includes evaluating thumb mobility, functionality, global aesthetics, and other quality of life aspects for each patient using their contralateral healthy thumb as a control. Data will be collected on preoperative metacarpophalangeal angle, type of skin flap used, surgical reconstruction technique, immobilization method, postoperative complications, and patient satisfaction with surgery and daily pain levels.
