The Risser scale (named after Dr. Joseph C. Risser) is a measurement of skeletal maturity or growth; it utilizes the fact that as a person’s skeleton matures during adolescence bone starts to form on the outer part of the iliac crest (upper edge of the pelvis) and calcifies inward along the ridge. After this bone formation is complete, the new bone growth fuses to the hip bone and this fusion is believed to correspond with full skeletal maturity. So, the degree of bone growth can be used to determine what stage of skeletal maturity has been reached.

Conveniently, the same X-ray that is taken to measure a patient’s Cobb angle can be used to determine this. A scale of 0–5 is used, where Risser 0 shows a significant amount of growth is still to happen while Risser 5 indicates full skeletal maturity.

Using the information below, one can determine the stage a patient has reached.

Risser 1 typically equates to the beginning of puberty, 3 is normally around mid-puberty, and 5 is a fully grown adult. Boys and girls start puberty at different ages, which normally means they finish at different ages. With girls normally starting at 11-12 and finishing at 16-17 and boys starting at 12-13 and finishing at 17-18.
