Disease definition Arthrogryposis multiplex congenita AMC is a congennita of disorders characterized by congenital limb contractures. The combined treatment options of conservative and surgical management have maximized the ambulatory and functional potential of affected individuals with arthrogryposis multiplex congenita.

Most patients have normal intelligence.

These DA syndromes are caused by fetal myopathy due to sarcomeric protein dysfunction causing muscle weakness and secondary joint contractures. In most cases, congeniita infants have contractures of various joints. Ehlers—Danlos syndrome with soft-tissue contractures.

Check this box if you wish to receive a copy of your message. Early physical therapy is very important, both to mobilize joints and to stimulate muscle growth and to prevent further muscular atrophy [ 31 ]. In males, the testes may fail to descend into the scrotum cryptorchidism.


AMC amyooplasia also occur as part of chromosomal disorders e. Arthrogryposis multiplex congenita amyoplasia: When contractile proteins go bad: A variant of Charcot—Marie—Tooth disease.

In some cases, the mother’s uterus does not allow for adequate fetal movement because of a lack of amniotic fluidknown as oligohydramniosor an abnormal shape to the uterus, called a bicornuate uterus. Muscle deficiency and respiratory function may require lower doses of muscle relaxants.

Amyoplasia – Wikipedia

Common deformities of the lower extremities include. However, surgical release of the affected joints is often necessary. The most common form of an isolated congenital contracture is clubfoot. Arthrogryposis is derived from the Greek word meaning “with crooking of joints. Chromosomal abnormalities associated with congenital contractures arthrogryposis Clin Genet.

Rare Disease Database

This subgroup is characterized by multiple congenital contractures. Connective tissue is the material between the cells of the body that gives tissues form and strength. It occurs in approximately 1in births and is associated with interuterine crowding and low amniotic fluid volume, but there are no preventive measures.

In amyoplasia, muscle congenitx is more congeenita than severity of joint contractures for the prediction of walking ability and functional level. Involvement of only the upper limbs was seen in four, only the lower limbs in six, and both the upper and lower limbs in 25 patients. Petersburg, Russia, September At least 10 different forms of distal arthrogryposis have been identified including Freeman-Sheldon syndrome, Gordon syndrome, trismus-pseudocamptodactyly syndrome, multiple pterygium syndrome and Sheldon-Hall syndrome.

Unusual clinical features in infantile spinal muscular atrophies. It may be suspected in utero, as it can be associated with diminished fetal movement during pregnancy, low amniotic fluid levels, or potential joint contractures seen on ultrasonography. Evaluate respiratory function clinical, chest radiographs, pulmonary function tests if possible, arterial blood gases analysis, CT scans.


Higher incidence is found in twins. Such factors would include fetal crowding in which there is not enough room for the fetus to move around such as when there are multiple births or uterine structural abnormalities. Other treatment is symptomatic and supportive. Two forms have been described:. A revised and extended classification of the distal arthrogryposes.

Movement restriction in utero caused by, e. What are the typical findings for this disease?


Further, a mutation in fetal myosin heavy chain MYH8 has been described in DA7, trismus-pseudocamptodactyly syndrome [ 19 ]. According to this, patients can be divided into three main groups of disorders: Causes, consequences and clinical course in amyoplasia and distal arthrogryposis.

Muscle development is poor and may be represented only by fibrous bands. Amyoplasia appears to be sporadic and not recur in families. Multiple diseases with isolated joint contractures have been associated with specific amyoolasia and have a known inheritance pattern.

Amyoplasia is common in one of monozygotic twins. Some cases of AMC are related to multiple factors including genetic and environmental ones multifactorial inheritance.
