Canal Fill of the Forearm Bones When Placing Intramedullary Nails in the Pediatric and Adolescent Populations.

This study found that there was not an association between the nail to canal diameter ratio and postoperative angulation in forearm fractures treated with flexible intramedullary nails. When choosing a flexible nail for forearm fractures, there does not appear to be an optimal ratio; it is therefore reasonable to use the ND that passes more easily.
