All the following regarding Risser's sign are true except (AIIMS May 2009)
|A||The iliac apophyses starts ossifying shortly after puberty ossification extends medially|
|B||Once the crests are completely ossified it is a sign of skeletal maturity|
|C||Rapid progression of the scoliotic curves take place after ossification of crests|
|D||Ossification of crests coincides with fusion of the vertebral ring apophyses|
Rapid progression of the scoliotic curves take place after ossification of crests
a. Risser's sign helps in assessment of skeletal maturity, this is important because the scoliotic curve often progresses most during the period of rapid skeletal growth and maturation.
b. The iliac apophyses start ossifying shortly after puberty ossification extends medially and once the iliac crests are completely ossified further progression of scoliotic curves is minimal.
