It is important to know the sequence of appearance since the ossification centers always appear in a strict order. On the lateral side this can result in a dislocation or a fracture of the radius with or without involvement of the olecranon. var windowOpen; An elbow joint effusion without a visible fracture seen on radiographs can suggest an occult fracture and should prompt further evaluation.
