Anomalies and Curiosities of Medicine [159]
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).
(2) A more or less developed organ, free at its extremity, and articulating with the head or sides of a metacarpal, metatarsal, or phalangeal bone.
(3) A fully developed separate digit.
(4) A digit intimately united along its whole length with another digit, and having either an additional metacarpal or metatarsal bone of its own, or articulating with the head of one which is common to it and another digit.
Superstitions relative to supernumerary fingers have long been prevalent. In the days of the ancient Chaldeans it was for those of royal birth especially that divinations relative to extra digits were cast. Among the ancients we also occasionally see illustrations emblematic of wisdom in an individual with many fingers, or rather double hands, on each arm.
Hutchinson, in his comments on a short-limbed, polydactylous dwarf which was dissected by Ruysch, the celebrated Amsterdam anatomist, writes as follows.--
"This quaint figure is copied from Theodore Kerckring's 'Spicilegium Anatomicum,' published in Amsterdam in 1670. The description states that the body was that of an infant found drowned in the river on October 16, 1668. It was dissected by the renowned Ruysch. A detailed description of the skeleton is given. My reason for now reproducing the plate is that it offers an important item of evidence in reference to the development of short-limbed dwarfs. Although we must not place too much reliance on the accuracy of the draughtsman, since he has figured some superfluous lumbar vertebrae, yet there can be no doubt that the limbs are much too short for the trunk and head. This remark especially applies to the lower limbs and pelvis. These are exactly like those of the Norwich dwarf and of the skeleton in the Heidelberg Museum which I described in a recent number of the 'Archives.' The point of extreme interest in the present case is that this dwarfing of the limbs is associated with polydactylism. Both the hands have seven digits. The right foot has eight and the left nine. The conditions are not exactly symmetrical, since in some instances a metacarpal or metatarsal bone is wanting; or, to put it otherwise, two are welded together. It will be seen that the upper extremities are so short that the tips of the digits will only just touch the iliac crests.
"This occurrence of short limbs with polydactylism seems to prove conclusively that the condition may be due to a modification of development of a totally different nature from rickets. It is probable that the infant was not at full term. Among the points which the author has noticed in his description are that the fontanelle was double its usual size; that the orbits were somewhat deformed; that the two halves of the lower jaw were already united; and that the ribs were short and badly formed. He also, of course, draws attention to the shortness of the limbs, the stoutness of the long bones, and the supernumerary digits. I find no statement that the skeleton was deposited in any museum, but it is very possible that it is still in existence in Amsterdam, and if so it is very desirable that it should be more exactly described,"
