The hands and feet of people with ectrodactyly are often described as "claw-like" and may include only the thumb and one finger (usually either the little finger, ring finger, or a syndactyly of the two) with similar abnormalities of the feet. [7] People with oligodactyly often have full use of the remaining digits and adapt well to their ...
In clubfoot, feet are rotated inward and downward. [1] [2] The affected foot and leg may be smaller than the other, while in about half of cases, clubfoot affects both feet. [1] [6] [7] Most of the time clubfoot is not associated with other problems. [1] Clubfoot can be diagnosed by ultrasound of the fetus in more than 60% of cases.
Mostly one neurovascular bundle can be identified, with no tendons present in the extra digit. In case of a fully developed extra finger, the duplication usually presents itself at the level of the metacarpophalangeal joint. A triplication of the little finger is very rare. Ulnar polydactyly occurs ten times more often in African populations. [11]
The digits at the borders of the cleft might be syndactilyzed, and one or more digits can be absent. In most types, the thumb, ring finger and little finger are the less affected parts of the hand. [7] The incidence of cleft hand varies from 1 in 90,000 to 1 in 10,000 births depending on the used classification.
This condition has been called zygodactyly or didactyly, but the specific arrangement in chameleons does not fit either definition. The feet of the front limbs in chameleons, for instance, are organized into a medial bundle of digits 1, 2 and 3, and a lateral bundle of digits 4 and 5, while the feet of the hind limbs are organized into a medial ...
Malformation associated with constriction ring syndrome. The percentage of associated anomalies varies from 40% to as high as 80% [16] [17] [19] Constriction ring deformities are as common on the lower extremity as on the upper, almost all of these involve the musculoskeletal system, with clubbed feet being the most common in up to 30% of ...
Medical genetics Brachydactyly type D , also known as short thumb , [ 3 ] [ 1 ] stub thumb , [ 5 ] [ 6 ] or clubbed thumb , [ 5 ] [ 6 ] is a genetic trait recognised by a thumb being relatively short and round with an accompanying wider nail bed.
Brachydactyly (from Greek βραχύς (brachus) 'short' and δάκτυλος (daktulos) 'finger') is a medical term denoting the presence of abnormally short digits (fingers or toes) at birth. The shortness is relative to the length of other long bones and other parts of the body. Brachydactyly is an inherited, dominant trait.
