Bone mineral density (BMD) in the second metacarpal bone was measured by Digital Image Processing method (DIP) in 146 female patients with senile osteoporosis. There was a significant correlation between age and the BMD, and also a correlation between BMD and the jidai index, which evaluated the degree of bone atrophy of the lumbar spine.
The fracture and deformity of the spine with osteoporosis was showed to depend on the degree of BMD of the second metacarpal bone.
When the BMD increased more than 2.1mm Al., the spine might not have the danger of the fracture and deformity.
We showed that the DIP method was a useful parameter in osteoporosis.
