Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to more porous bone, and consequent increase in fracture risk. It is the most common reason for a broken bone among the elderly. [3]
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).
Bone disease refers to the medical conditions which affect the bone. [1] Terminology. A bone disease is also called an "osteopathy ", but because the term ...
Osteogenesis imperfecta (IPA: / ˌ ɒ s t i oʊ ˈ dʒ ɛ n ə s ɪ s ˌ ɪ m p ɜːr ˈ f ɛ k t ə /; [4] OI), colloquially known as brittle bone disease, is a group of genetic disorders that all result in bones that break easily. [1]: 85 [9] The range of symptoms—on the skeleton as well as on the body's other organs—may be mild to severe.
Disease occurs along a broad clinical spectrum ranging from mostly asymptomatic incidental lesions, to severe disabling disease. Disease can affect one bone , multiple (polyostotic), or all bones (panostotic) [4] [5] and may occur in isolation or in combination with café au lait skin macules and hyperfunctioning endocrinopathies, termed McCune ...
High bone density, Acro-osteolysis and obtuse mandibular angle are the characteristic radiological findings of this disorder. [10] Pycnodysostosis also causes problems that may become evident with time. Aside from the broken bones, the distal phalanges and the collar bone can undergo slow progressive deterioration.
Paget's disease of bone (commonly known as Paget's disease or, historically, osteitis deformans) is a condition involving cellular remodeling and deformity of one or more bones. The affected bones show signs of dysregulated bone remodeling at the microscopic level, specifically excessive bone breakdown and subsequent disorganized new bone ...
Avascular necrosis (AVN), also called osteonecrosis or bone infarction, is death of bone tissue due to interruption of the blood supply. [1] Early on, there may be no symptoms. [1] Gradually joint pain may develop, which may limit the person's ability to move. [1] Complications may include collapse of the bone or nearby joint surface. [1]
