Abstract:
Objective To observe the treatment effect of minimally invasive surgery on bone defects. Methods Bone defect model was established in bilateral shaft of radius in 30 rabbits. Forefoots of each rabbit were then randomized into open grafting group(group A) and minimally invasive grafting group(group B). Minimally invasive bone grafting was performed in group B with self-made instruments. DEXA and electron microscopy were investigated in radial bone defect after six rabbits were sacrificed randomly at different time after bone grafting. Results DEXA showed bone density increased gradually in both groups, the bone density in minimally invasive group was higher than that in open group with significant difference(P
