Correlation Between Distal Radial Cortical Thickness and Bone Mineral Density

Are Orthopedic Surgeons Subjective Intraoperative Conclusions About Bone Mass Accurate?

“…Moreover, the orthopedic surgeons in this study were not blinded to the radiographs, as radiographs are mandatory tools in orthopedic operations; therefore, interpretation of the radiographs may have influenced the surgeons' conclusion given post operatively. Previous studies have shown that estimation of the cortical thickness of the distal radius from standard radiographs of the wrist in the post anterior view can be correlated with the BMD [15]. In our study, 24% of patients had a wrist fracture.…”

Evaluation of trabecular bone score in patients with a distal radius fracture

“…It has been reported that patients with a displaced DRF have lower cortical bone density than that of patients with a nondisplaced DRF [26]. In addition, bicortical thickness of the distal radius on a radiograph and cortical thickness of the distal radius on HR-pQCT are studied as indicators of bone quality [24,27]. Furthermore, metacarpal cortical bone density, which is assessed by digital X-ray radiogrammetry, is significantly associated with a DRF in elderly women [28,29].…”

“…Furthermore, metacarpal cortical bone density, which is assessed by digital X-ray radiogrammetry, is significantly associated with a DRF in elderly women [28,29]. The occurrence of DRF is significantly related to hip BMD but not lumbar spine BMD [5,27], and severity of a DRF and cortical thickness of the distal radius are not related to BMD of the lumbar spine, which is mainly trabecular [27,30]. Second, even if trabecular microstructure affects frailty of the distal radius, it may not be accurately evaluated by the lumbar spine TBS due to anatomic site differences.…”

A Novel Method for Estimation of Femoral Neck Bone Mineral Density Using Forearm Images from Peripheral Cone Beam Computed Tomography

“…Even though the femoral neck and the forearm bones are not directly associated with each other, similar research effort has been conducted on the relationship between BMDs from different sites. In [25][26][27], the results showed that that some parameters from the cortical bone in distal radius and ulnar on anteroposterior radiograph could reflect the femoral neck BMD. In [25], the distal radius BMD was correlated with the ratio of the outside cortical shell diameter to the inside cortical shell diameter at the metaphyseal/diaphyseal junction.…”

“…In [26], radiologic density of dental structure from CBCT imaging could provide information of lumbar vertebra and femoral neck. In [27], the radial bicortical widths were measured at 50 and 70 mm proximal to the distal ulnar articular surface, and the mean bicortical width was compared with each patient's femoral BMD. The results showed that bicortical thickness of the distal radius was positively correlated with femoral neck BMD.…”
