ABSTRACTInformation about the development of ossifications of the elbow comes from the anglosaxon literature, that states: lateral condyle appears before the year of age, but is has been reported since the one month of age, and it could be delayed until the 18-24 months; for the medial epicondyle between 5-6 years of age; for the trochlea between the 9-10 years of age; the lateral epicondyle, which is the latest to ossify, between 10-12 years; for proximal radius between 3.8 and 4.5 years; and for the olecranon, taking the primary ossification center like reference, between 6 and 8 years. We studied 240 elbows divided in 6 groups according to the age of development. Anteroposterior and lateral roentgenograms were taken of the elbow, finding delay in the development of the olecranon and the medial epicondyle. Taking into consideration our clinical observations, the development of the ossification process, is observed later in the Mexican child.
