The Latinate term osteogenesis imperfecta was coined by Dutch anatomist Willem Vrolik in 1849; ... Life expectancy in type IV OI is thought to be close to normal, but ...
Other conditions that can produce similar symptoms include mandibuloacral dysplasia, pyknodysostosis, osteogenesis imperfecta, and Hajdu-Cheney syndrome. [5] Treatment includes supportive measures such as a device to protect the skull and dental care. [5] Surgery may be performed to fix certain bone abnormalities. [4] Life expectancy is ...
The clinical features of COL1A1/2-related osteogenesis imperfecta can be highly variable ranging from severe and lethal perinatal fractures to individuals with minimal tendency to repeated fractures and skeletal deformities and with a normal stature and life span.
Fibrodysplasia ossificans progressiva (/ ˌ f aɪ b r oʊ d ɪ ˈ s p l eɪ ʒ (i) ə ɒ ˈ s ɪ f ɪ k æ n z p r ə ˈ ɡ r ɛ s ɪ v ə /; [1] abbr. FOP), also called Münchmeyer disease or formerly myositis ossificans progressiva, is an extremely rare connective tissue disease in which fibrous connective tissue such as muscle, tendons, and ligaments turn into bone tissue (ossification).
Dwarfism is a condition of people and animals marked by unusually small size or short stature. [1] In humans, it is sometimes defined as an adult height of less than 147 centimetres (4 ft 10 in), regardless of sex; the average adult height among people with dwarfism is 120 centimetres (4 ft).
Life expectancy may be plateauing. Don’t expect your grandkids to live to 200 years old. A study published on Monday suggests we may be reaching our limit in terms of life expectancy and that ...
Achondroplasia is one of several congenital conditions with similar presentations, such as osteogenesis imperfecta, multiple epiphyseal dysplasia tarda, achondrogenesis, osteopetrosis, and thanatophoric dysplasia. This makes estimates of prevalence difficult, with changing and subjective diagnostic criteria over time.
Craniocervical instability is more common in people with a connective tissue disease, including Ehlers-Danlos syndromes, [1] osteogenesis imperfecta, and rheumatoid arthritis. [2] It is frequently co-morbid with atlanto-axial joint instability, Chiari malformation , [ 3 ] or tethered spinal cord syndrome .
