No diffuse osteoporosis in lumbar scoliosis but lower femoral bone density on the convexity.

The aims of our study were to find out, in 15 female volunteers with untreated structural lumbar idiopathic scoliosis, through dual-photon X-ray absorptiometry measurements, whether femoral bone mineral density (BMD) was different between the right and the left side and whether this difference was related to scoliosis convexity. We showed that no statistical significant difference between femoral neck BMD measured on both sides of the same patient (p = 0.6). However, neck BMD from the same side as the convexity side was significantly lower than the opposite one.
