, epiphyseal fracture
separation of the epiphysis of a long bone, caused by trauma. See: Salter-Harris classification of epiphysial plate injuries.

epiphyseal fracture

Etymology: Gk, epi + phyein, to grow, fractura, break
a fracture involving the epiphyseal plate of a long bone, which causes separation or fragmentation of the plate. Also called Salter fracture.

epiphyseal fracture

A separation of the epiphysis from the bone between the shaft of the bone and its growing end. It occurs only in skeletally immature patients. See: Salter-Harris fracture.
See also: fracture


emanating from or pertaining to the epiphysis.

epiphyseal aseptic necrosis
caused by (1) idiopathic primary necrosis of the epiphysis in growing small-breed dogs (Legg-Calvé-Perthes disease); (2) fracture of the femoral neck; or (3) epiphyseal slippage, particularly of the femoral head in young dogs, cats, pigs, calves and foals. The disease has a characteristic radiographic appearance.
epiphyseal cartilage
between the epiphysis and the diaphysis of long bones; growth at the cartilage is responsible for continuing growth of the bone; when growth ceases the cartilage disappears. Called also growth plate, physis.
epiphyseal detachment
epiphyseal dysplasia
an inherited defect of dogs characterized by very short limbs and early degenerative arthropathy. Called also chondrodystrophia fetalis and pseudoachondroplastic dysplasia of Miniature poodles. A similar histological lesion occurs in multiple epiphyseal dysplasia in Beagles.
epiphyseal fracture
one involving the epiphysis. See also salter classification.
epiphyseal plate
the thin plate of cartilage between the epiphysis and the shaft of a long bone; it is the site of growth in length and is obliterated by epiphyseal closure. Called also growth plate, physis.
epiphyseal scar
on radiographs, the radiodense band seen at the junction of the epiphysis and metaphysis, which represents the closed physis.
