Background:
Radius shaft greenstick fractures in children can be a challenging injury to treat because angulation and rotational alignment are difficult to assess.
Methods:
In this report, we describe a simple method for analyzing the deformity and identifying rotational and angular malalignment. This technique involves analyzing the forearm radiographs as 2 segments, proximal and distal, and assuring that the rotational position of each matches the other.
Results:
We present 3 cases of proximal radius greenstick fractures in malalignment to demonstrate the radius crossover sign.
Conclusions:
Identifying the radius crossover sign, and proceeding with further closed reduction may prevent deformity that could otherwise result in a significant loss of forearm motion.
Level Of Evidence:
Level V.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
