OBJECTIVES: Although fractures occur in various bones, including long, short, and flat bones, fracture repair investigations focus on the diaphysis of the long bone. The cell composition, osteogenic capacity, and bone matrix differ among osteogenesis patterns. However, the differences in the bone repair process have not been studied. Here, we compared the bone repair processes in the parietal bone and scapula of adolescent mice. METHODS: Bone apertures were created in the parietal bone and scapula. Samples were collected at indicated times after surgery, and the repair process was analyzed using micro-computed tomography, histological, immunohistochemical, and mRNA expression analyses. RESULTS: In both repair processes, cartilage formation was not detected on the periosteum side. The parietal bone aperture was gradually filled with newly formed bone produced from the edge of the aperture by day 14 but was not completely repaired even by day 49. In the scapula, a bony callus was detected on the periosteum at day 7, and the aperture was bridged by day 14. Subsequently, the bony callus was remodeled to the original bone architecture. Alkaline phosphatase activity and osteocalcin synthesis occurred earlier in the repair region of the scapular periosteum, compared with that in the parietal periosteum. The mRNA expression of osteogenic markers in the periosteum was markedly upregulated in the scapula versus the parietal bone. CONCLUSION: Our study findings clarify the differences between parietal bone and scapula repair and suggest that the bone repair process differs among ossification patterns.
