Varalakshmi V, a girl from Bangalore with eight fingers on each hand and about four to five extra toes on each foot. [72] Volcacius Sedigitus, a Roman poet of the 1st century, probably received his epithet, signifying "Sixfinger", because he was born with six fingers on each hand, according to Pliny. [73]
Human hand anatomy (pentadactyl) In biology, dactyly is the arrangement of digits (fingers and toes) on the hands, feet, or sometimes wings of a tetrapod animal. The term is derived from the Greek word δακτυλος (dáktylos) meaning "finger." Sometimes the suffix "-dactylia" is used. The derived adjectives end with "-dactyl" or "-dactylous."
Polysyndactyly can be diagnosed in utero through sonographic and genetic testing, though sonography may be preferred due to the cost and risk associated with genetic testing. [19] Ultrasounds, typically done at the 14th to 16th week of pregnancy , can detect the presence of extra metacarpals , metatarsals , or phalanges .
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 ...
The hand of a person with Greig cephalopolysyndactyly with syndactyly of several digits. Syndactyly can be simple or complex. [2] In simple syndactyly, adjacent fingers or toes are joined by soft tissue. In complex syndactyly, the bones of adjacent digits are fused. The kangaroo exhibits complex syndactyly. Syndactyly can be complete or incomplete.
This condition can be a symptom of other genetic disorders, such as Holt–Oram syndrome and Fanconi anemia. This trait is autosomal dominant and often runs in families (hence "familial"). [ 1 ] Sometimes big toe duplication, post-axial polydactyly, and syndactyly of the hand and feet can occur alongside this malformation [ 2 ] [ 3 ...
Camptodactyly is a medical condition that causes one or more digits (fingers or toes) to be permanently bent. It involves fixed flexion deformity of the proximal interphalangeal joints. Camptodactyly can be caused by a genetic disorder. In that case, it is an autosomal dominant trait that is known for its incomplete genetic expressivity. This ...
Symbrachydactyly is a congenital abnormality, characterized by limb anomalies consisting of brachydactyly, cutaneous syndactyly and global hypoplasia of the hand or foot. [1] In many cases, bones will be missing from the fingers and some fingers or toes may be missing altogether.
