Extension type II pediatric supracondylar humerus fractures: a radiographic outcomes study of closed reduction and cast immobilization.

Background: The treatment of Gartland type II pediatric supracondylar humerus fractures remains controversial. Some argue that closed reduction and cast immobilization is sufficient to treat these fractures, whereas others advocate closed reduction and percutaneous pinning. The purpose of this radiographic outcomes study was to determine whether closed reduction and cast immobilization could successfully obtain and maintain acceptable reduction of extension type II supracondylar humerus fractures.
