Abstract

Elbow instability following injury in children is uncommon. Most children heal their fractures and ligament injuries uneventfully following dislocation and/or fracture. There are occasionally children that have persistent posterolateral or medial valgus instability. Posterolateral rotatory instability results is recurrent elbow subluxation/dislocation and medial instability results in pain during valgus stress, such as throwing or weight bearing. These entities are distinctly different and disparate with regard to diagnosis and treatment. Hence, a separate discussion is necessary and will be divided accordingly.
