This study demonstrated that the addition of a third pin to malreduced humeral fractures improves stability.Supracondylar fractures are common in children between the ages of 4 and 7 years. Displaced fractures are usually managed with reduction and percutaneous pinning, as this reduces the incidence of angular deformities and neurovascular complications associated with cast immobilization and skeletal traction. However, it is not always possible to completely reduce this sort of fracture, and the commonly accepted deformity is internal rotation of the distal fragment. This study was conducted to determine which configuration of pin placement is most stable in this malreduced position.
