- W2360101851 abstract "Objective To study the efficacy of the non-vascularized structural bone graft in the treatment of bone defects.Methods This study first established bone defect model,choose 38 New Zealand white rabbits,and succeed to establish femur bone defect model. which were randomly divided into A,B,C and three groups( n = 12). take on the same side for autologous iliac bone graft source,and the iliac cut size equal to 8 along the trabecular bone or stress direction. Reducted the femur,and fixed by mini-plate and screw. Group A plant iliac in femoral defect with femur stress( bone trabeculae) in the same direction; Group B planting iliac block in the direction that perpendicular to the explants of femoral stress( trabecular bone); Group C randomly implanted in the femoral defect area. Observed the generral conditions of rabbits,and evaluated the X-ray and new blood capillary and positive cells of CD34 dyeing. Results The femur bone defect range : 13 ~ 14mm. The bony callus of target area and X-ray in three groups after operation: little difference on second week,significant difference on fourth week and indifference on eighth weeks. positive cells of CD34 dyeing and new blood capillary after operation: significant difference on second or fourth week( P0. 05),and indifference on eighth week( P0. 05). Conclusion The non-vascularized structural bone graft in the treatment of bone defects,with the derection of trabecular bone or stress direction grafting is influential in early healing of bone defects,the graft trabecular direction and the bone in the same direction planting in the early bone healing is superior to the vertical direction of the bone grafting." @default.
