A Salter–Harris fracture is a fracture that involves the epiphyseal plate (growth plate) of a bone, specifically the zone of provisional calcification. [2] It is thus a form of child bone fracture. It is a common injury found in children, occurring in 15% of childhood long bone fractures. [3]
The epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.It is the part of a long bone where new bone growth takes place; that is, the whole bone is alive, with maintenance remodeling throughout its existing bone tissue, but the growth plate is the place where the long bone grows longer (adds length).
The cockade sign is a radiological feature associated with intraosseous lipoma, a rare benign tumor of the bone composed primarily of mature adipose tissue. [1] [2] This sign describes the characteristic appearance of a central calcification or ossification surrounded by radiolucent fatty tissue on imaging, resembling a bullseye or cockade.
Radiography typically show widening of the zones of provisional calcification of the metaphyses secondary to unmineralized osteoid. Cupping, fraying, and splaying of metaphyses typically appears with growth and continued weight bearing. [ 47 ]
Zone of calcification In this zone, chondrocytes are either dying or dead, leaving cavities that will later become invaded by bone-forming cells. Chondrocytes here die when they can no longer receive nutrients or eliminate wastes via diffusion. This is because the calcified matrix is much less hydrated than hyaline cartilage. Zone of ossification
If coronary calcification is identified, Dr. Postalian says the main focus is stopping any more buildup from happening. This, he says, is done in a few different ways. One is to consider ...
An epiphysis (from Ancient Greek ἐπί (epí) 'on top of' and φύσις (phúsis) 'growth'; pl.: epiphyses) is one of the rounded ends or tips of a long bone that ossify from one or more secondary centers of ossification.
