In the following X-ray of the wrist, what is the exact age?
Show Hint
Count and size the ossification centers and match them to a hand bone age atlas.

- 2 yrs
- 8 yrs
- 6 yrs
- 9 yrs
Show Solution
The Correct Option is C
Solution and Explanation
Approach this as an atlas-matching exercise. Skeletal (bone) age before puberty is read from how many ossification centers have appeared and how wide the epiphyses have grown, weighted most heavily at the distal phalanges, then middle, then proximal, plus the carpal bones.
The maturation rule: each phalangeal epiphysis starts thin and widens until its transverse width matches the neighbouring metaphysis. Comparing the centers visible on this wrist film against the Greulich-Pyle hand bone age standards places the child at roughly $6$ years.
So among the choices, the closest atlas match is option (c), 6 years.
