pertaining to growth or to that part of a bone that is responsible for lengthening—the physis.
physeal delayed closure
occurs when there is inadequate growth hormone, as in hypopituitarism.
essentially a disease of horses which consists of a self-limiting disturbance of endochondral ossification affecting the metaphyseal physes of young horses; called also physitis, epiphysitis.
physeal focal closure
occurs as a result of damage to or displacement of the growth plate; bony bridges develop uniting the epiphysis and the metaphysis, many leading to bone deformities.
physeal premature closure
usually the result of injury and seen most often in dogs. Causes abnormal development of the bone, the type and severity depending on the age of the animal and the particular location. The most vulnerable are the radius and ulna, mainly because closure of one physis results in unequal growth of the two parallel bones and angular deformity often results.
