Delayed union in pediatric forearm fractures.

Background: The aim of this study was to assess the predictive factors of delayed union in pediatric forearm fractures. Few previous reports have approached this complication, but contrary to these studies we excluded cases with known pathogenic factors and included in the sample cases treated with conservative methods.

Methods: This is a case-control study of all pediatric shaft forearm fractures presenting delayed union in a minimum follow-up period of 12 months, from 2003 through 2009, in a hospital covering a health area.
