When does the P3 epiphyseal plate close?

Explanation:
Growth plates allow bones to lengthen during development, and when a plate fuses, that bone stops growing in length at that location. For the distal phalanx, known as P3, the plate fuses from birth. That means there is no further longitudinal growth from P3 after birth, so the timing of closure is at birth. The other timeframes would imply ongoing growth from P3 after birth, which isn’t the case here.
