A Salter–Harris fracture is a fracture that involves the epiphyseal plate or growth plate of a bone. It is a common injury found in children, occurring in 15% of childhood long bone fractures.〔 ==Types== There are nine types of Salter–Harris fractures; types I to V as described by Robert B Salter and W Robert Harris in 1963, and the rarer types VI to IX which have been added subsequently: * Type I – transverse fracture through the growth plate (also referred to as the "physis"): 6% incidence * Type II – A fracture through the growth plate and the metaphysis, sparing the epiphysis: 75% incidence, takes approximately 2–3 weeks to heal. * Type III – A fracture through growth plate and epiphysis, sparing the metaphysis: 8% incidence * Type IV – A fracture through all three elements of the bone, the growth plate, metaphysis, and epiphysis: 10% incidence * Type V – A compression fracture of the growth plate (resulting in a decrease in the perceived space between the epiphysis and metaphysis on x-ray): 1% incidence * Type VI – Injury to the peripheral portion of the physis and a resultant bony bridge formation which may produce an angular deformity (added in 1969 by Mercer Rang) * Type VII – Isolated injury of the epiphyseal plate (VII–IX added in 1982 by JA Ogden) * Type VIII – Isolated injury of the metaphysis with possible impairment of endochondral ossification * Type IX – Injury of the periosteum which may impair intramembranous ossification 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Salter–Harris fracture」の詳細全文を読む スポンサード リンク
