These are a separate class of genetically mediated congenital contractures, characterized by the presence of pterygia: The thumb is usually adducted.
These diseases are caused by cohgenita of genes encoding skeletal muscle proteins, ryanodine receptors, or mutations of the gene encoding nuclear lamins A and C laminopathies [ 40 — 49 ].
Pectus excavatum Pectus carinatum. Clinical examples of multiple congenital contractures — arthrogryposis — in neonates. The earlier the restriction of active fetal motion occurs, the greater artrogripzois arthrogryposis severity; it is also considered that fibrosis of periarticular structures — both the ligaments and the articular capsule — may be responsible for the tendency of the affected joints to return to their original fetal position despite the used treatment, i.
The Journal of Hand Surgery. However, aside from the severity of contractures and the used treatment, this function is affected by the power of the pelvic girdle and the quadriceps muscles as well as upper limb function [ 70 ]. General Discussion Arthrogryposis is a general or descriptive term for the development of nonprogressive contractures affecting one or more areas of the body prior to birth congenitally. Their common feature is the presence of congenital, usually non-progressive joint contractures involving at least two different body areas.
