What causes Erlenmeyer flask deformity?
This deformity results from defective bone modeling (under-modeling) at the meta-diaphyseal [di-metaphyseal] region leading to straight uncurved [or even laterally bowed] di-metaphyseal borders and cortical thinning giving the appearance of EFD [Castriota-Scanderbeg and Dallapiccola, 2005].
What is a Erlenmeyer flask used for?
Mixing
Erlenmeyer flask/Uses
Erlenmeyer flasks are used to contain liquids and for mixing, heating, cooling, incubation, filtration, storage, and other liquid-handling processes. Their slanted sides and narrow necks allow the contents to be mixed by swirling without the risk of spills, which is useful for titrations and for boiling liquids.
What is Pyle disease?
Pyle disease is a disorder of the bones. Its hallmark feature is an abnormality of the long bones in the arms and legs in which the ends (metaphyses) of the bones are abnormally broad; the shape of the bones resembles a boat oar or paddle.
What are the benefits of using an Erlenmeyer flask instead of a beaker?
Erlenmeyer flasks are great for mixing chemicals since they have a wide base and can be swirled around without spillage. Since the base is wide, there is less danger of the liquid rising to the top and spilling out. The Erlenmeyer filter flask also has the advantage of avoiding tipping over.
What are the symptoms of Pyle?
Pyle disease is a bone disorder characterized by knock knees (genu valgum), relative constriction of the diaphysis or shaft of the bone and flaring of the metaphysis or end of the bone (Erlenmeyer flask deformity), widening of the ribs and collarbones, flattening of the bones of the spine (platyspondyly), and thinning …
What is Erlenmeyer flask bone deformity (EFD)?
1 Clinical Genetics, Department of Pediatrics, Riyadh Medical Complex Hospital, Riyadh, Kingdom of Saudi Arabia. [email protected] Erlenmeyer flask bone deformity (EFD) is a long-standing term used to describe a specific abnormality of the distal femora.
What is the pathophysiology of osteopetrosis?
Osteopetrosis can cause bones to dissolve and break. It is one of the hereditary causes of osteosclerosis. It is considered to be the prototype of osteosclerosing dysplasias. The cause of the disease is understood to be malfunctioning osteoclasts and their inability to resorb bone.
How is osteopetrosis diagnosed?
Abstract Osteopetrosis is a rare inherited bone disease where bones harden and become abnormally dense. While the diagnosis is clinical, it also greatly relies on appearance of the skeleton radiographically. X-ray, radionuclide bone scintigraphy and magnetic resonance imaging have been reported to identify characteristics of osteopetrosis.
What is the root word of osteopetrosis?
The term osteopetrosis is derived from the Greek word “osteo” meaning bone and “petros” meaning stone. Osteopetrosis is referred to as “marble bone disease” and “Albers-Schönberg disease”, after the German radiologist credited with the first description of the condition in 1904 [1].
