Factors related to growth insult

Factors related to risk of growth insultDescription of possible factors
Severity of the injuryIf the injury causes the blood supply to the epiphysis to be cut-off, growth can be stunted. If the growth platae is shifted, shattered or crushed, a bony bridge is more likely to form, and the risk of growth retardation is higher.
Age of the childIn a younger child, the bones have a great deal of growing to do; therefore, growth arrest can be more serious.
GenderOn average, ossification of the secondary centres of the major long bones begins earlier and is completed earlier in girls than in boys.
Which growth plate is injuredSome growth plates, such as those of the region of the knee, are more responsible for extensive bone growth than others.
Type of growth plate fracturesAcute growth plate injuries have been classified by the level of severity. Since the 1960s, the Salter–Harris classification, which divides most growth-plate fractures into five categories based on type of damage, has been most widely used. A newer classification, called the Peterson classification, adds a type VI fracture, in which a portion of the epiphysis, growth plate and metaphysis is missing.
