What is the Salter-Harris classification?
The Salter-Harris classification system is a method used to grade fractures that occur in children and involve the growth plate, which is also known as the physis or physial plate. The classification system grades fractures according to the involvement of the physis, metaphysis, and epiphysis.
What is a Physeal fracture?
Practice Essentials. Growth plate (physeal) fractures may be defined as disruptions in the cartilaginous physis of long bones that may or may not involve epiphyseal or metaphyseal bone.
What are the patterns of fracture?
Linear Fracture: the break is parallel to the bone’s long axis. Oblique Fracture: the break has a curved or sloped pattern. Pathologic Fracture: caused by a disease that weakens the bones. Spiral Fracture: one part of the bone has been twisted at the break point.

What is Perichondrial ring?
The perichondrial ring is a circumferential ring in the periphery of the epiphyseal cartilage. Cell cultures derived from the ring of La Croix biopsy specimens show a high rate of cell proliferation and cell migration in vitro.
What does Physeal mean?
[ fĭz′ē-əl ] adj. Relating to the area of bone that separates the metaphysis and the epiphysis, in which the cartilage grows.
What happens if a kid breaks his growth plate?
Growth plate fractures often need immediate treatment because they can affect how the bone will grow. An improperly treated growth plate fracture could result in a fractured bone ending up more crooked or shorter than its opposite limb. With proper treatment, most growth plate fractures heal without complications.
