Figure 6

Histologic sections of porous Ti6Al4V scaffolds implanted into goat metatarsus large segmental defects and semi-quantitative of new bone area in the scaffolds. At 3 months, callus in the periphery regions had formed; apparent bone ingrowth was observed at 6 months; at 12 months, the inner space of the scaffolds was nearly completely filled with bone tissue. New bone area increased with time and, compared with the middle position, both ends had relatively more amounts of new bone, with the proximal position being superior to the distal position. Stain: Stevenel’s blue and Van Gieson’s picrofuchsin. Purple indicates bone; black indicates materials; blue indicates fibrovascular tissue.
