Several surgeries may be needed to correct this type of fracture as it is almost always a very complex fracture that requires a skilled orthopedic surgeon, usually a ‘specialist’, familiar with this type of injury.
Hyperflexion of the elbow to maintain reduction should be avoided, as the swollen tissues may compromise the traversing brachial artery and lead to decreased perfusion pressure.
Once clinical and radiographic healing has occurred, generally after weeks, the cast is removed and gradual return to activities is encouraged. A full neurologic, vascular and compartment exam should be performed before and after reduction.
Intra-operative fluoroscopic arthrogram may be the more expedient choice in this scenario. In conjunction with the bimodal distribution, diaphyseal forearm fractures in young males are commonly due to high-energy trauma, for example, falls from height, sports injuries, motor vehicle accidents, and fractures in elderly females are due to low-energy trauma such as a ground level fall.
