Detailed explanation-1: -However, it is clinically important to realize that the ossification centers always appear in a specific sequence. The mnemonic of the order of appearance of the individual ossification centers is C-R-I-T-O-E: Capitellum, Radial head, Internal (medial) epicondyle, Trochlea, Olecranon, External (lateral) epicondyle.
Detailed explanation-2: -Bone ossification, or osteogenesis, is the process of bone formation. This process begins between the sixth and seventh weeks of embryonic development and continues until about age twenty-five; although this varies slightly based on the individual.
Detailed explanation-3: -The ossification centre for the capitellum develops at one year and then is followed by the radial head, medial epicondyle, trochlea, olecranon and lateral epicondyle. This order of appearance is specified in the mnemonic C-R-I-T-O-E (see Table 2).
