Insights
Arterial disease in men is linked to male osteoporosis. Patients with arterial disease showed reduced bone mineral density and increased vertebral fractures, suggesting a connection between circulatory health and bone integrity.
Area of Science:
- Bone biology and vascular health
- Orthopedics and cardiovascular disease
Background:
- Bone metabolism and circulation are closely linked.
- Osteoporosis is associated with reduced intra-osseous capillaries.
- Arteriosclerosis may affect intra-osseous arterioles.
Purpose of the Study:
- To investigate the potential link between arteriosclerosis and male osteoporosis.
- To explore the etiology of male osteoporosis.
Main Methods:
- Studied 17 male patients with arterial disease (Leriche stage 2-4) and 15 age-matched controls.
- Assessed phosphorus-calcium balance, spinal X-rays, and bone density (spine and femoral neck).
Main Results:
- 9 out of 17 patients with arterial disease had wedge fractures, compared to none in the control group.
- Significantly reduced bone mineral content was observed in the femoral neck of the arterial disease group.
Conclusions:
- Findings suggest a link between arteriosclerosis and male osteoporosis.
- Arterial disease may contribute to reduced bone mineral density and increased fracture risk in men.
Abstract:
There are close links between bone metabolism and bone circulation. Osteoblasts are derived from the walls of the venous sinuses. As shown by Burkardt, osteoporosis is accompanied by a decrease in the number of intra-osseous capillaries, and intra-osseous arterioles may be the site of arteriosclerosis lesions. In order to determine the existence of a possible link between arteriosclerosis and male osteoporosis, the etiology of which is often poorly defined, the authors studied phosphorus-calcium balance, X-rays of the spine, and bone density of the spine and the femoral neck in 17 male arterial disease sufferers with a mean age of 61 and at Leriche stage 2, 3 or 4. These 17 patients were compared with 15 age-paired controls. Wedge fractures, absent in the control group, were seen in 9 of the 17 patients. Bone mineral content in the femoral neck was significantly reduced in the arterial disease group.
