Kohler gives photographs of quite a remarkable case of
suppression and deformity of the digits of both the fingers and
toes.
Figure 123 shows a man who was recently exhibited in
Philadelphia. He had but two fingers on each hand and two toes on
each foot, and resembles Kohler's case in the anomalous digital
conformation.
Figure 124 represents an exhibitionist with congenital
suppression of four digits on each hand.
Tubby has seen a boy of three in whom the first, second, and
third toes of each foot were suppressed, the great toe and the
little toe being so overgrown that they could be opposed. In this
family for four generations 15 individuals out of 22 presented
this defect of the lower extremity. The patient's brothers and a
sister had exactly the same deformity, which has been called
"lobster-claw foot."
Falla of Jedburgh speaks of an infant who was born without
forearms or hands; at the elbow there was a single finger
attached by a thin string of tissue. This was the sixth child,
and it presented no other deformity. Falla also says that
instances of intrauterine digital amputation are occasionally
seen.
According to Annandale, supernumerary digits may be classified as
follows:--
(1) A deficient organ, loosely attached by a narrow pedicle to
the hand or foot (or to another digit).
