What is the Risser classification?

What is the Risser classification?

The Risser classification is used to grade skeletal maturity based on the level of ossification and fusion of the iliac crest apophyses. It is primarily in planning corrective surgery for scoliosis.

When does iliac crest apophysis close?

The average chronologic age when the iliac apophysis is completed is 14 years in girls and 16 years in boys. It may occur as early as 10 or 11 years in girls and 13 or 14 in boys, and as late as 17 or 18 years in girls or 20 years in boys.

What is Risser classification used for?

What does the Risser stage show on a pelvic radiograph?

The Risser staging system is widely used to assess the potential for progression of spinal curvature in AIS in combination with other predictive factors such as triradiate cartilage closure, mean height velocity, Tanner’s staging, radiographs of hand and elbow, and chronological age [12].

What is a Risser jacket?

Risser jacket – a scoliosis plaster jacket. Risser localizer scoliosis cast. Risser method.

How many stages are there in the Risser stage system?

The Risser Staging System. Risser divided the steps of ossification and fusion of the iliac apophysis into six stages (Risser Stages 0–5), with the higher numbers describing advancement toward skeletal maturity.

What is the purpose of the Risser classification?

The Risser classification is used to grade skeletal maturity based on the level of ossification and fusion of the iliac crest apophyses.

How is the Risser classification used in scoliosis?

The Risser classification is used to grade skeletal maturity based on the level of ossification and fusion of the iliac crest apophyses. It is primarily in planning corrective surgery for scoliosis. Classification. As stage 0 and stage 5 can appear similar, age and long bone growth plates may be of help in discriminating the two.

Which is a stage of the Risser-Ferguson method?

The Risser-Ferguson method involves assigning stages from 0 to 5 to the process of ossification and attachment of sections of the pelvis, known as the iliac apophysis. Ossification is the process of bone tissue formation.
