What are Risser stages?

What are Risser stages?

The Risser Staging System Stage 0 describes an x-ray on which no ossification center is seen in the apophysis, whereas Stage 5 represents complete ossification and fusion of the iliac apophysis. Two slightly different versions of the Risser system are in use; the differences concern Stages 2 to 4 [2, 3, 13].

What is Risser stage1?

Doctors follow the amount of ossification on a patient’s x-ray to determine the Risser sign (pelvis must be visualized). This is best seen from an AP (anteroposterior) standing full-spine x-ray and is referred to as ‘capping. ‘ This capping occurs from the outside to inside of the iliac crest (see image below).

How does a spica cast work?

Spica (body) casts are used to keep the thighbone (femur) and pelvis still. We call this immobilization. This cast holds the joint above the hip (the spine) and the joint below the hip (the knee) still, so that the femur and pelvic bones stay still to heal.
