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

AIM: To analyse bone remodeling in regard to the age of scaphoid non-unions(SNU) with ***: Thirty-six patients with symptomatic SNU underwent surgery with resection of the pseudarthrosis. The resected material was evaluated histologically after staining with hematoxylin-eosin(HE), tartrate resistant acid phosphatase(TRAP), CD 68, osteocalcin(OC) and osteopontin(OP). Histological examination was performed in a blinded ***: The number of multinuclear osteoclasts in the TRAP-staining correlated with the age of the SNU and was significantly higher in younger SNU(P = 0.034; r = 0.75). A higher number of OP-immunoreactive osteoblasts significantly correlated with a higher number of OC-immunoreactive osteoblasts(P = 0.001; r = 0.55). Furthermore, a greater number of OP-immunoreactive osteoblasts correlated significantly with a higher number of OP-immunoreactive multinuclear osteoclasts(P = 0.008; r = 0.43). SNU older than 6 mo showed a signifi-cant decrease of the number of fibroblasts(P = 0.04). Smoking and the age of the patients had no influence on bone remodeling in ***: Multinuclear osteoclasts showed a significant decrease in relation to the age of SNU. However, most of the immunhistochemical findings of bone remodeling do not correlate with the age of the SNU. This indicates a permanent imbalance of bone formation and resorption as indicated by a concurrent increase in both osteoblast and osteoclast numbers. A clear histological differentiation into phases of bone remodeling in SNU is not possible.
