    ¡¾Abstract¡¿ AIM: To investigate the iliac cancellous bone structure and turnover parameters in the elderly patients with distal radius fracture. METHODS: Iliac bone of 14 senile patients with distal radius fracture and 12 young patients with distal radius fracture were obtained and bone histomorphometric analysis was made. RESULTS: The trabecular bone volume, trabecular density and nodeª²terminus ratio in the experiment group were significantly lower than those in the control group, and the trabecular separation in the experiment group was higher than that in the control group. There was no difference in the osteoid thickness and osteoid surface between the experiment group and the control group but the eroded surface in the experiment group was significantly higher than that in the control group. CONCUSION: Elderly people suffer from osteoporosis to some degree and the bone structural and morphological change is one of the causes of the decrease in mechanical strength leading to frequent fracture. ......
