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."
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 ...
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 .
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 ...
The inheritance of cleft hand is autosomal dominant and has a variable penetrance of 70%. [6] Cleft hand can be a spontaneous mutation during pregnancy (de novo mutation). The exact chromosomal defect in isolated cleft hand is not yet defined. However, the genetic causes of cleft hand related to syndromes have more clarity. [13]

Acrocephalosyndactyly presents in numerous different subtypes, however, considerable overlap in symptoms occurs. Generally, all forms of acrocephalosyndactyly are characterized by atypical craniofacial, hand, and foot characteristics, such as premature closure of the fibrous joints in between certain bones of the skull, [16] [17] fusion of certain fingers or toes, [16] [18] and/or more than ...
