Slipped capital femoral epiphysis (SCFE) is a common hip disorder in adolescents, characterized by an abnormal lateral displacement of the femoral head from the femoral neck. It is classified based on the Salter-Harris classification system, which is commonly used to describe growth plate fractures in children. The classification system divides SCFE into three types based on the severity of displacement and the involvement of the epiphyseal plate.
Type 1 SCFE involves a mild displacement of the femoral head without any disruption of the growth plate. Type 2 SCFE is the most common type and involves a more severe displacement of the femoral head, with some disruption of the epiphyseal plate. Type 3 SCFE is the most severe type and involves a complete separation or fracture of the growth plate, leading to significant displacement of the femoral head.
The Salter-Harris classification system is important in determining the appropriate treatment for SCFE, as more severe types may require surgical intervention to prevent long-term complications such as avascular necrosis or degenerative joint disease. Early diagnosis and classification of SCFE using the Salter-Harris classification system can help guide treatment decisions and improve outcomes for patients with this condition.
What is a Salter-Harris fracture radius?
A growth plategrowth plateThe epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.https://en.wikipedia.org › wiki › Epiphyseal_plateEpiphyseal plate – Wikipedia fracture of the distal radius is a fracture line that intersects the physis. Salter-Harris is a numbering system used to classify the location of the fracture on the bone. The Salter-Harris number tells us what kind of fracture your child has, but it does indicate how severe the fracture is.
What is Salter-Harris classification?
The Salter-Harris classification system is a method used to grade fractures that occur in children and involve the growth plategrowth plateThe growth plate is the area of tissue near the ends of long bones in children and teens that determines the future length and shape of the mature bone. Each long bone has at least two growth plates, one at each end, and they are longer than they are wide.https://www.niams.nih.gov › growth-plate-injuriesGrowth Plate Injuries in the Foot, Hip & More | NIAMS, which is also known as the physis or physial plate. The classification system grades fractures according to the involvement of the physis, metaphysismetaphysisThe metaphysis ( pl. : metaphyses) is the neck portion of a long bone between the epiphysis and the diaphysis. It contains the growth plate, the part of the bone that grows during childhood, and as it grows it ossifies near the diaphysis and the epiphyses.https://en.wikipedia.org › wiki › MetaphysisMetaphysis – Wikipedia, and epiphysisepiphysisAn epiphysis (from Ancient Greek ἐπί (epí) ‘on top of’, and φύσις (phúsis) ‘growth’; pl. : epiphyses) is one of the rounded ends or tips of a long bone that ossify from a secondary center of ossification.https://en.wikipedia.org › wiki › EpiphysisEpiphysis – Wikipedia.
What are the 4 zones of the physis?
The cells of the physis are arranged in columns or layers described as the germinal or resting layer, the proliferative zone, the hypertrophic zone and the zone of provisional calcification (Figure 10).
What is the Salter-Harris fracture zone?
A Salter-Harris type I fracture refers to a fracture line that runs straight across the growth plategrowth plateThe epiphyseal plate, epiphysial plate, physis, or growth plate is a hyaline cartilage plate in the metaphysis at each end of a long bone.https://en.wikipedia.org › wiki › Epiphyseal_plateEpiphyseal plate – Wikipedia, involving the cartilage without affecting the bone. Type I may cause the epiphysis, or the rounded end of the bone, to separate from the rest of the bone.
