. With advancing age both sexes have an increased incidence of osteoporotic fractures, although fractures are more common in women than in men. Whereas in women several potential risk factors have been identified, less is known about osteoporosis in men. A total of 27 Austrian men (mean age: 65 ± 2 years) with atraumatic spine fractures were studied. In all patients, medical history gave no evidence of disease or medications causing osteoporosis. Peripheral bone mass was determined by single‐photonabsorptiometry on the distal non‐dominant forearm; lumbal bone density was measured by quantitative computed tomography. Serum levels of calcium, phosphate, alkaline phosphatase, osteocalcin, testosterone, estrogen, parathyroid hormone and 25‐hy‐droxy‐vitamin D as well as 2‐h‐urinary‐OH proline and calcium excretion were measured. All data were compared with those of an age and sex matched control group consisting of 19 healthy males. A significant difference in mean peripheral and axial bone mass (SPA: P <0.004; QCT: ( P <0.001) was observed between osteoporotic men and controls. When compared to controls, serum levels of alkaline phosphatase ( P <0.012), urinary OH proline ( P <0.05) and urinary calcium excretion ( P <0.003) were significantly higher in the osteoporotic males. Additionally, there was a significant positive correlation between serum alkaline phosphatase and urinary OH proline excretion ( r =0.32; P <0.04) in the osteo‐porotics. All other biochemical parameters showed no significant differences. Our results may lead to the assumption that osteopenia in men is related to increased bone turnover.
