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.
Both are near SHFM1 ("split hand/foot malformation type 1"). Ectrodactyly is an inherited dysmelia, and often occurs in both the hands and the feet. Its inheritance pattern is autosomal dominant. It affects about 1 in 90,000 babies, with males and females equally likely to be affected.
SHFM is a rare congenital condition that features a range of presentations with varying degrees of digital hypoplasia and clefting of the hands/feet that gives a characteristic 'lobster claw' appearance.
Cleft hand occurs when a child's hand doesn't develop properly during pregnancy. The condition can sometimes be detected on a routine prenatal ultrasound. After the baby is born, the deformity is visible. Although cleft hand usually affects both hands, it can also occur in only one hand.
The causes of Claw Hand might include: Nerve damage in the arm e.g ulnar palsy, median palsy, ulnar tunnel syndrome, cubital tunnel syndrome. Congenital birth defect. Some genetic diseases such as Charcot-Marie-Tooth Disease.
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.
After two hours of work, the doctors were able to fix 80 per cent of the malformation. After recovering, the boy could move his hand like normal. Seeing the positive result, the doctors decided to conduct another surgery to fix the right hand and both feet. He is recovering well.
The ectrodactyly, ectodermal dysplasia, and clefting (EEC) syndrome is an autosomal dominant disorder characterized by a lobster-claw limb anomaly (ectrodactyly), which may be present in one or more limbs, cleft lip and palate, and ectodermal dysplasia.
Cleft hand refers to a group of congenital hand abnormalities in which the central bony elements are missing. It is the fifth most common congenital anomaly of the hand 1. The condition is known by different names like ectrodactyly, pincer split hand, lobster claw hand, crab claw hand and split hand complex.
Split hand/foot malformation (SHFM) is a limb abnormality that is present at birth. It is characterized by absence of certain fingers and toes (ectrodactyly) that suggest a claw-like appearance and webbing of fingers and toes may also be present.
Congenital anomalies of the hand very often have an autosomal dominant pattern of inheritance and most of them have a monogenic genetic basis with variable penetrance[1].
Claw hand can be a type of congenital hand difference that you're born with, or it can be caused later in your life by an injury or another health condition. Most cases of claw are caused by damage to your ulnar nerve, the nerve that controls some of the muscles that flex and extend your fingers.
What is Kabuki syndrome? Kabuki syndrome is a rare congenital disorder, meaning that a child is born with the condition. Children with Kabuki syndrome usually have distinctive facial features, mild to moderate mental impairment and growth problems.
Intellectual disability-spasticity-ectrodactyly syndrome is a rare intellectual disability syndrome characterized by severe intellectual disability, spastic paraplegia (with wasting of the lower limbs) and distal transverse defects of the limbs (e.g. ectrodactyly, syndactyly, clinodactyly of the hands and/or feet).
Individuals with Apert syndrome have syndactyly of the fingers and toes . The severity of the fusion varies, although the hands tend to be more severely affected than the feet. Most commonly, three digits on each hand and foot are fused together. In the most severe cases, all of the fingers and toes are fused.
Syndactyly is the medical definition for having webbed fingers or toes (digits). It's one of the most common birth defects that affect babies' hands and feet. Syndactyly in fingers is a form of congenital hand difference.
When an extra digit is located in the center of the hand, it is called central polydactyly. Polydactyly is the most common congenital hand deformity. It affects boys and girls equally. Black children are more likely to have ulnar polydactyly, and Asian and white children are more likely to have radial polydactyly.
From physical therapy to prosthetic devices, and splints to surgery, there are many ways to help children and adults with congenital hand and upper extremity conditions. Dr. Fishman says many children will not need an intervention to improve function.
MYTH: Children with a cleft are 'disabled' or have learning difficulties. FACT: A cleft is not a 'disability'. It may affect a child in ways that mean they need extra help, but most children with a cleft are not affected by any other condition and are capable of doing just as well at school as any other child.
Babies with symbrachydactyly (sim-BRA-chi-DAK-til-ee) are born with short fingers, which may be webbed, or they are missing fingers. Usually this happens on only 1 hand, and the other hand looks typical. Some of the finger bones (phalanges, fah-LAN-jeez) may be smaller than is typical, and the fingers may be stiff.
Syndactyly is a condition in which children are born with fused or webbed fingers. About half of children with syndactyly have it in both hands (bilateral). Most of the time, syndactyly affects the fingers. Sometimes it affects the toes, but not as often.
Lifespan is normal in nearly all types of ectodermal dysplasia.
Ectrodactyly, ectodermal dysplasia, and cleft lip/palate syndrome (EEC) syndrome is a rare genetic disorder with an incidence of around 1 in 90,000 in population.
The abnormal gene can be inherited from either parent, or can be the result of a new mutation (gene change) in the affected individual. The risk of passing the abnormal gene from affected parent to offspring is 50% for each pregnancy regardless of the sex of the resulting child.
