Thumb duplication is a rare anomaly. Here we describe two neonatal cases of thumb duplications, one type II and the other IV. Seven types have been described in medical literature. Radiological assessment important differentiating between these types.

Polydactyly being most common congenital digital anomaly of the hand and needs special consideration. Surgical treatment is warranted in most of the cases because of cosmetic and functional reasons. In this article, we describe a 5-year-old female child who was having bilateral thumb duplication. The diagnosis was clinical, and it does not fit into any mentioned classification systems in litera...

Within the Oberg, Manske, Tonkin (OMT) classification, thumb duplications are a failure of formation and/or differentiation affecting the radial-ulnar axis of the hand plate. The Wassel description of seven types of thumb duplication provides a good structure from which an approach to management is based. The aim of surgical reconstruction is to obtain a stable, mobile thumb of adequate size an...

Congenital duplication of the thumb is usually reconstructed by 18 months of age. This paper reports satisfactory outcome following reconstruction of two Wassel Type IV duplicate thumbs in adults aged over 40. Both achieved a good outcome based on Tada's criteria and a subjective Visual analogue score 8.
