title: Radius crossover sign:  an indication of malreduced radius shaft greenstick fractures.
abstract: 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.
