Osteogenesis imperfecta is a group of genetic disorders, all of which cause bone fragility. OI has high genetic heterogeneity , that is, many different genetic mutations lead to the same or similar sets of observable symptoms ( phenotypes ).
Diagnosis of Bruck syndrome must distinguish the association of contractures and skeletal fragility. Ultrasound is used for prenatal diagnosis. The diagnosis of a neonate bears resemblance to arthrogryposis multiplex congenital, and later in childhood to osteogenesis imperfecta. [1]
These include osteogenesis imperfecta, [63] Multicentric carpotarsal osteolysis syndrome, [69] Multicentric Osteolysis, Nodulosis, and Arthropathy, [70] Marfan syndrome, [63] hemochromatosis, [4] hypophosphatasia [71] (for which it is often misdiagnosed), [72] glycogen storage diseases, homocystinuria, [63] Ehlers–Danlos syndrome, [63 ...
In classic non-deforming osteogenesis imperfecta with blue sclerae or common variable osteogenesis imperfecta with normal sclerae, nearly 60% of cases are de novo. COL1A1/2-related osteogenesis imperfecta is identified by repeated fractures with trivial trauma, defective dentinogenesis imperfecta (DI), and hearing loss.
It was first discovered in 1972 by Bianchine et al. when they described three families with osteogenesis imperfecta, pseudoglioma, retinoblastoma, and recurrence of bone fractures. [ 8 ] References
A pathologic fracture is a bone fracture caused by weakness of the bone structure that leads to decrease mechanical resistance to normal mechanical loads. [1] This process is most commonly due to osteoporosis, but may also be due to other pathologies such as cancer, infection (such as osteomyelitis), inherited bone disorders, or a bone cyst.
The uses of bisphosphonates include the prevention and treatment of osteoporosis, Paget's disease of bone, bone metastasis (with or without hypercalcemia), multiple myeloma, primary hyperparathyroidism, osteogenesis imperfecta, fibrous dysplasia, and other conditions that exhibit bone fragility.
It can be useful to enquire about symptoms of osteogenesis imperfecta, as Type I Dentinogenesis Imperfecta (Shield's Classification) is associated with osteogenesis imperfecta. [2] Notable information includes: History of bone fracture caused by minimal trauma; Short stature; Blue sclera; Hearing loss [2] [5]
