Body
was changed:
There are six ossification centres of the elbow that appear and develop in a relatively reproducible fashion, and are key to assessment of the paediatric elbow radiograph. Timing of their appearance varies in the literature but an approximation is given below. A useful mnemonic to remember the order of development is CRITOL or CRITOE (see video below).
capitellum: 2-24 months
radial head: 3-6 years
internal (medial) epicondyle: 4-7 years
trochlea: 8-10 years
olecranon 8-10 years
external (lateral) epicondyle: 10-13 years
