Duplicated Thumb – Extra Thumb

Special efforts and skill are necessary to reconstruct double thumbs or duplicated thumbs. Though the child may have two thumbs, but each component will be smaller than the normal single thumb. The plan is to create as normal and a stable thumb as possible. The bigger of the two thumbs is usually retained as the main thumb and tissues from the other thumb can be utilized to augment the retained thumb or provide stability.

If the two components are linked at the joint level, then reconstruction of the joint after removal of the extra thumb is a must.
