What is mirror hand?

Also known as: mirror hand deformity, mirror hand syndrome, ulnar dimelia.

Mirror hand is a very rare congenital difference. In most cases, there is mirrored symmetry of the hand with a central digit and 3 digits on either side and no thumb. There are usually 7 or 8 digits, with middle, ring and small fingers seen on either side of the central digit.

Differences are often seen in the forearm and elbow as well. Movement in the fingers, forearm and elbow may be limited.
