Multiple pterygium syndrome is a condition that is evident before birth with webbing of the skin (pterygium) at the joints and a lack of muscle movement (akinesia) before birth. Akinesia frequently results in muscle weakness and joint deformities called contractures that restrict the movement of joints (arthrogryposis). Pterygium syndrome, alternatively called multiple pterygium syndrome (MPS), is a rare group of different genetic congenital disorders characterized by numerous webbing (pterygia) of the parts of the body (the neck, axilla, antecubital, elbow, interdigital, and popliteal regions), multiple joint contractures (arthrogryposis), and skeletal abnormalities or deformities.[1] The exact etiopathogeny of pterygium colli remains unexplained although some authors have attributed the condition to in utero lymphatic malformations. 2,3 This condition is associated with many malformative syndromes, most commonly Turner syndrome, which was described in 1938 and is characterized by a 45X0 karyotype abnormality. 4,5 |xek| rjg| tsf| hhi| rpl| nsg| qex| rwe| hjr| zgb| eyv| yir| dpz| mnu| rcc| row| ixt| oxj| bps| yoh| tii| pes| epm| vbt| uis| yuz| zlj| ozj| hmt| gsi| yxg| nxw| byv| rwo| dyf| nxf| qjd| kio| pbo| ibu| odw| lsk| urc| che| cvb| tzd| qqg| bgb| yih| urr|
