In "The Relationship of Angulation to Translation in Fracture Deformities" (76-A: 390-397, March 1994), by Green and Gibbs, the label ? on Figure 1 (page 391) should have indicated the supplement of the angle that it indicates at present, to correspond to the angles labeled ø and T. With the figure remaining as printed, the legend should state: "If both roentgenograms demonstrate an angular deformity (ø and T) at the same level, then the true angle of the apex of the deformity (180°-?) is always greater than the deformity seen on either orthogonal roentgenogram, and the true plane of the deformity (A) is located somewhere between the two planes."
