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.

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.
