Figure 6From: Evaluation of accuracy of plain radiography in determining the Risser stage and identification of common sources of errorsPseudo-fusion. (A) Plain radiography of a 15-year-old girl; a sclerotic line was visible on the posterior iliac crest suggesting fusion of the iliac apophysis, and the patient was graded as Original Risser stage 5 and French Risser stage 4. (B) A coronal 3D reconstruction view; there was no definite fusion of the apophysis , and the patient was graded as Original Risser stage 4 and French Risser stage 3. Estimating the initiation of pseudo-fusion is difficult on plain radiography.Back to article page
