[Articular hypermotility syndrome (AHS): clinical characteristics and specific features of AHS-related rheumatoid arthritis and osteoarthritis].

Articular and extraarticular manifestations of AHS were studied in 114 AHS patients. Locomotor complaints were getting more frequent and serious with progression of AHS. Rheumatoid arthritis arising in the presence of hypermotility was characterized by minor symptoms and destructive changes and was not very active. Functional performance of the joints was not much affected. Osteoarthrosis in AHS presence ran with more pronounced symptoms, with early emergence of degenerative changes in the joints, primarily, of the lower limbs.
