Evaluation of bone remodeling in regard to the age of scaphoid non-unions

Figure 3 Non-union tissue in the hematoxylin-eosin staining. A: Non-union tissue with fibrocartilage covered by a layer of synovium-like lining cells (arrow) of a 60-mo-old SNU; B: Fibrous tissue rich in fibroblasts of a 10-mo-old SNU. Note the contrast in cell number as compared to the 60-mo-old SNU in A; C: Fibrous tissue with few fibroblasts, same patient as in A. Original magnification 100 × (A), 200 × (B, C). SNU: Scaphoid non-unions.
