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] .

2024年10月14日 · Ectrodactyly, also known as split hand/foot malformation (SHFM) of cleft hand, is a rare genetic condition in which one or more of your baby’s middle fingers or toes are missing or malformed. All four hands and feet may be affected. Treatment depends on the severity of your child’s condition and can be complex.

Lobster-claw deformity, also called ectrodactyly is an uncommon congenital presentation occurring in the hand due to longitudinal failure of development of second, third or fourth ray. It occurs in 1 to 4 newborns in 100,000 live births.

Split-hand/split-foot malformation (SHFM)/ectrodactyly, also known as “lobster claw hand,” is a limb malformation involving the central rays of the autopod and presenting with syndactyly, median clefts of the hands and feet and aplasia/or hypoplasia of …

2022年10月25日 · Ectrodactyly (also known as a split hand-split foot malformation, cleft hand or lobster claw hand) is a skeletal anomaly predominantly affecting the hands (although the feet can also be affected). The condition has a highly variable severity. The estimated incidence is at ~ 1 in 90,000-150,000 births.

Spectrum of hand and foot defects with missing digits, median cleft and fusion of the remaining digits resulting in clawlike extremities. Associated abnormalities: Chromosomal abnormalities: found in trisomy 18. High incidence of genetic syndromes. The most common are: Roberts syndrome: autosomal recessive; ectrodactyly, phocomelia, facial cleft.

Cleft hand, lobster claw hand and ectrodactyly are different names given to central deficiencies of the hand due to longitudinal failure of formation of 2 nd, 3 rd or 4 th ray. It has an incidence of 1 to 4 in 100000 live births 1. Associated anomalies include tibial aplasia, mental retardation, ectodermal defects, orofacial clefting and ...

Cleft hand, lobster claw hand and ectrodactyly are different names given to central deficiencies of the hand due to longitudinal failure of formation of 2 nd, 3 rd or 4 th ray. It has an incidence of 1 to 4 in 100000 live births 1.

Lobster Claw Hand Syndrome, also known as lobster syndrome or ectrodactyly, is a rare congenital hand anomaly that affects individuals from birth. It is characterized by a hand malformation that resembles the claw of a lobster. This condition presents as a split hand deformity, with the middle fingers missing or partially formed.

Ectrodactyly (absence of one or more digits) can be present with clefting in the proximal portion of hand or foot known as split hand foot malformation (SHFM) or lobster claw deformity. SHFM can be of four types depending upon the different responsible chromosomal loci.
