epiphyseal fracture

Etymology: Gk, epi + phyein, to grow, fractura, break

epiphyseal

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

see epiphysiolysis.

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.
