DRU Classification

The following pictures focus on the above highlighted area of a hand.

Example 1

Radius (grade 10) and ulna (grade 8) growth plates nearly fused. This patient is almost completely mature and will not grow further.


Example 2

“Spike” or “capping” over medial radius but not lateral (grade 7) suggests this patient is still near the growth spurt and should be observed closely.


Example 3

No capping seen (Radius grade 6 and ulna grade 5) suggesting this patient is skeletally immature and is at the growth spurt.


Example 4

The epiphysis is not as wide as the metaphysis of both radius (grade 5) and ulna (grade 4) indicating a skeletally immature patient who is likely not at the peak growth spurt yet.
