Changes in bone histomorphometry and bone mineral during treatment of osteoporosis with 1 alpha-hydroxyvitamin D3 and calcium.

Treatment with 1 alpha-OHD3 supplemented with calcium will possibly unveil symptoms of spinal pain (8/10) and increase physical activity (7/10) in patients suffering from osteoporosis. An increase in trabecular bone (8/10) as well as a decrease in bone resorption (9/10) accompanied by measured increased bone mineral (6/10) has been observed. Some patients did not show any response to this kind of treatment.
