epiphyseal plate

Etymology: Gk, epi, above, phyein, to grow, platys, flat
a thin layer of cartilage between the epiphysis, a secondary bone-forming center, and the bone shaft. The new bone forms along the plate. Epiphyseal plates remain open until late adolescence. Also called growth plate.

epiphyseal plate

The thin layer of cartilage between the epiphysis and the shaft of a bone. Growth in length of the bone occurs at this layer.

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.

3) However, because UBCs almost exclusively affect skeletal areas associated with the most rapid longitudinal growth and originate near or in contact with the epiphyseal plate, a local growth aberration is most likely.
Growth ceases when the cartilaginous epiphyseal plates separating these portions ossify.
After examining X-rays, paediatric radiologist Ralph Lachman, co-director of the International Skeletal Dysplasia Registry at Cedars-Sinai Medical Centre in Los Angeles, concluded that the skeletal development, based on the density of the epiphyseal plates of the knees (growth plates at the end of long bones found only in children), surprisingly seemed to be equivalent to that of a six- to eight-year-old kid.
In this study the existence of epiphyseal plate at the proximal extremity of tibia was doubtful that maybe causes the increase in the size of the diaphysis in all specimens or it was the secondary center of ossification that cause the traction epiphysis.
Individuals were considered young of the year if cartilaginous epiphyseal plates in finger joints were visible to the unaided eye when the wing was transilluminated (Anthony 1988).
Lorenz developed a huge reputation for his manipulative treatment of club feet, which he accomplished by essentially stretching or breaking the tendons, ligaments, and epiphyseal plates until the foot was appropriately aligned.
