Bone Mineral Density (BMD) was measured by Dual-Energy X-Ray Absorptiometry (DXA) in 101 patients with OPLL who were treated conservatively and compared to 86 healthy adult volunteers.Estimation of BMD was carried out in the cervical, and lumbar vertebral bodies, and radius.In the cervical and lumbar vertebral bodies BMD of OPLL patients were higher than that of controls.However, BMD in the radial diaphysis was not significantly different betwreen OPLL patients and controls. In the metaphysis of the radius BMD was slightly higher in OPLL patients compared to controls. BMD value incveased in cancellous bone in comparison with cortical bone in OPLL.
