Ektrodaktiliya
Description:
Ektrodaktiliya is a heterogeneous group of anomalies of brushes and feet. Clinical manifestations vary. Meet both partial, and total absence of one or several fingers, and sometimes and proximal departments of brushes and feet (metacarpal and plusnevy bones) formation of a crevice. Allocate typical and atypical forms of a cleft hand and foot.
Ektrodaktiliya symptoms:
The typiform of splitting is followed or an aplasia of the central beams and existence of the deep cone-shaped crevice dividing a brush into two parts (a kleshneobrazny brush) or an aplasia of radial beams and lack of a crevice (monodactylism).
The cleft hand can be combined with a syndactylia, a brachydactyly, a clinodactyly, an underdevelopment of fingers and a crevice of foot. The isolated lack of one finger of a brush more often happens unilateral and usually is not followed by defeat of feet.
Atypical splitting is characterized by an underdevelopment (more rare absence) average components of a brush and/or foot. The crevice in this case superficial, has an appearance of a wide interdigital interval.
Ektrodaktiliya
Ektrodaktiliya reason:
Population frequency — 1:90 000 (a typical cleft hand), 1:160000 (an atypical cleft hand).
Ratio of floors — M1:Zh1.
The mode of inheritance — cases of the isolated lack of one finger of a brush usually sporadic, a cleft hand, accompanying with similar deformation of foot, Is inherited on autosomal dominantly type with various expressivity and penetrance, cases of autosomal and recessive inheritance are described.
Treatment of an ektrodaktiliya:
Treatment of an ektrodaktiliya at early children's age is not carried out. Different plastic surgeries can be made at teenage age with the cosmetic purpose and for improvement of function of a brush or foot.
