May 8, 2025 · The Risser sign (iliac aphosyseal fusion indicates vertebral growth completion) was first described in 1958 by Joseph C. Risser (1892–1982), an American orthopedic surgeon 3-5.

Evaluating Risser sign to help estimate bone age (and thus skeletal maturity and risk for scoliosis progression) is easily done during a spine x-ray as the pelvis is imaged at the time of the spine.

Oct 15, 2024 · The Risser sign, also known as the Risser scale, is a way to check bone maturity. It looks at how bones fuse together, but it may not give a complete picture of their development.

The “Risser+ ” grade can efectively combine the North American and European Risser Classifications for skeletal maturity with adequate intra-rater/inter-rater reliability and agreement.

The Risser sign is an indirect measure of skeletal maturity, whereby the degree of ossification of the iliac apophysis by x-ray evaluation is used to judge overall skeletal development.

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.

The Risser scale is a system used to assess skeletal maturity through an X-ray of the pelvis, focusing on the ossification of the iliac crest. The scale ranges from Risser 0 to Risser 5, with 0 indicating no …

Dec 2, 2025 · The Risser Stage is the standard medical gauge for skeletal maturity. Learn how orthopedists use it to accurately predict remaining growth.

May 9, 2025 · There are different ways to assess a patient’s scoliosis and help predict their progressive rate; Risser stage measures skeletal maturity and growth potential.

May 12, 2022 · The Risser sign measures skeletal development - all you need is an x-ray of the pelvis. With the x-ray, you can see the ossification of the iliac apophysis as it progresses from the crest …
