Age of Ossification of Carpal Bones Capitate - 1 Month Hamate - 2 Months Triquetral - 3 Years Lunate - 4 Years Scaphoid - 5 Years Trapezoid - 6 Years Trapezium - 6 Years Pisiform - 12 Years Not the most accurate, but the 1-2-3-4-5-6-6-12 rule helps me remember the age of ossification of the carpal bones! A memory aid for the sequence: Looking from the VOLAR ASPECT, for the LEFT hand it is clockwise and anti-clockwise for the RIGHT hand. - Dr. Devpriyo Pal @drdevradiology #Ossification #Age #Carpal #Bones #wrist #radiology #mnemonic #diagnosis #msk #pediatrics
