Polydactyly is one of the most common congenital deformities with an incidence of between 5 and 17 per 10,000 live births. Super-numerary digits of the foot present most commonly at the fibular border. A super-numerary digit arising from the dorsum of the foot has only been described on two occasions. In one case, the digit was thought to be a skin appendage. In the other, the digit shared morphological features with its neighbours but was relatively hypo-plastic and was incapable of active movement. The child was non-syndromic. We present a case of a mobile, active super-numerary digit arising from the dorsum of the foot, the first of its kind to be described in the literature. The child had the rare congenital disorder Kabuki syndrome.
