Such disorders are usually inherited. Overall prognosis for children with amyoplasia is good. A classification of the investigated patients with arthrogryposis into different specific diagnoses identified the three largest groups, in decreasing order, as amyoplasia, DA syndromes, and arthrogryposis with CNS involvement. Connective tissue is the material between the cells of the body that gives tissues form and strength.

DA9, Beals syndrome, has also been found to be a collagen disorder with a mutation in the fibrillin FBN2 gene [ 23 ]. Two forms have been described: Arthrogryposis, Amyoplasia, Distal arthrogryposis, Muscle involvement, motor function, Contractures, Sarcomeric protein dysfunction.

Rare congenital disorder constituting about one third of cases of Arthrogryposis Multiplex Congenita characterized by multiple contractures of joints. J Bone Joint Surg Am.

Causes, consequences and clinical course in amyoplasia and distal arthrogryposis. A mutation in the fast skeletal muscle troponin I gene causes myopathy and distal arthrogryposis.

Accessed December 31, The joint contractures can also be more resistant to treatment in certain types of AMC, especially amyoplasia [ 31 ], and surgery and splinting may need to be planned accordingly.

Arthrogryposis multiplex congenita

Several studies report that neurogenic arthrogryposis of the amyoplasia type can be caused by vascular compromise in early fetal development, with ischemia of anterior horn cells leading to fetal akinesia and poor or absent muscle development, but also, in some cases, to co-existing anomalies with presumed vascular genesis, i.

Standard Therapies Treatment The treatment of AMC is directed toward the specific findings that are apparent in each individual. This page was last edited on 16 Octoberat Prenatal counseling may be suggested; however, it is of limited use if a specific diagnosis is not known. Sign in via Shibboleth.

The fetal akinesia in amyoplasia is thought to be caused by various maternal and fetal abnormalities. With aggressive therapy, individuals may suffer from stress fractures of the involved extremities.

Intelligence in these ayoplasia is normal. Six children had clinical signs of myopathy; different genetic syndromes were identified or suspected in ten children Larsen syndrome, Turner syndrome, facio-audio-symphalangism syndrome Sprenger syndromesix children had arthrogryposis in the lower extremities only, two of these with vertebral anomalies and caudal regression syndrome, and a further 12 children had arthrogryposis that we could not specify further.

In a retrospective epidemiologic study in western Sweden cobgenita Darin et al.

Several disorders, which are associated with abnormalities of connective tissue development, have been associated with multiple congenital contractures including diastrophic dysplasia, metatropic dwarfism, popliteal pterygium syndrome and Larsen syndrome.
