[Bone density of the lumbar spine and femur in acromegaly].

Abstract

Acromegaly is regarded as a cause for secondary osteoporosis, whereas recent papers suggest that growth hormone increases bone mineral density (BMD). In 16 patients with active acromegaly we found an increased BMD compared to normal controls in the lumbar spine and the proximal femur by means of dual energy X-ray absorptiometry. This increase in BMD was statistically significant in the femoral neck and in Ward's triangle (P = 0.05). Moreover, no signs of osteoporosis were found radiologically.
