Assessment of the normal and pathological alignment of the elbow in children using the trochleocapitellar index.

Background: The current research is a retrospective study that involves the description of a new trochleocapitellar index (TCI), on basis of anteroposterior (AP) radiographs of normal and fractured paediatric elbows. This index may be useful in assessing the alignment of the elbow with a supracondylar fracture.

Methods: The index was evaluated to define its normal and pathological range in children between the ages of 1-13 years.
