Ectrodactyly, split hand, or cleft hand [1] (from Ancient Greek ἔκτρωμα (ektroma) 'miscarriage' and δάκτυλος (daktylos) 'finger') [2] involves the deficiency or absence of one or more central digits of the hand or foot and is also known as split hand/split foot malformation (SHFM). [3]
Thumb hypoplasia is a spectrum of congenital abnormalities of the thumb varying from small defects to complete absence of the thumb. [1] It can be isolated, when only the thumb is affected, and in 60% of the cases [2] it is associated with radial dysplasia [1] (or radial club, radius dysplasia, longitudinal radial deficiency). Radial dysplasia ...
The technique contains a composite wedge resection of the central bone and soft-tissue. This will be achieved with approach of the lateral tissue of each thumb. The goal is to achieve a normal thumb, what concerns the size, which is possible. [12] If the width of the nail bed is greater than 70% of the contralateral thumb, it may be split. [44 ...
Hand and foot defects seen in Saethre-Chotzen syndrome. Webbing between the second and third finger and between the second and third toes [2] Short fingers and toes (brachydactyly) [4] Broad thumb and/or a broad hallux (big toe) with a valgus deformity (outward angulation of the distal segment of a bone/joint) [6]
a short thumb with radial deviation; complex syndactyly of the index, long and ring finger; symbrachyphalangism; simple syndactyly of the fourth webspace; The deformity of the space between the index finger and the thumb may be variable. Based on this first webspace, three different types of hand deformation can be diffentiated:
Rubinstein–Taybi syndrome presents itself from birth, and is usually hallmarked by delayed physical and cognitive growth. [citation needed] Typical features of the disorder include: Broad thumbs and broad first toes and clinodactyly of the 5th finger [4] Mental disability; Small height, low bone growth, small head; Cryptorchidism in males
Adducted thumb syndrome recessive form is a rare disease affecting multiple systems causing malformations of the palate, thumbs, and upper limbs.The name Christian syndrome derives from Joe. C. Christian, the first person to describe the condition.
Phocomelia is a congenital condition that involves malformations of human arms and legs which result in a flipper-like appendage. [1] [2] A prominent cause of phocomelia is the mother being prescribed the use of the drug thalidomide during pregnancy; however, the causes of most cases are to be determined.
