The aim of this study was to test the precision and reliability of measurements of the bone mineral density (BMD) of the trapezium in patients with osteoarthritic trapeziometacarpal joints using dual-energy X-ray absorptiometry scans and to assess whether there is an acceptable correlation between the BMD of the trapezium and that of the distal radius, for which normative data exist. We included 66 patients (52 women, 14 men) diagnosed with Eaton-Glickel stage II-IV osteoarthritis and a mean age of 59 years (range 40-77) in a prospective study. We found good intra- and inter-observer agreement of BMD measurements. Reliability was also good in repeated measurements. There was an indication of an increase in BMD with progression in the Eaton-Glickel stage. There was only a moderate correlation between the BMD of the trapezium and that of the radius.
本研究的目的是使用双能X线吸收测定扫描来测试患骨关节炎的大多角骨-掌骨关节患者大多角骨骨密度（BMD）测量的精确度和可靠性，并评估大多角骨的骨密度与已有标准数据的桡骨远端骨密度之间是否存在可接受的相关性。在一项前瞻性研究中，我们纳入了66例确诊为伊顿-格利克尔II-IV期骨关节炎、平均年龄59岁（范围40-77岁）的患者（52例女性，14例男性）。我们发现骨密度测量在观察者内和观察者间具有良好的一致性。重复测量时可靠性也良好。有迹象表明，随着伊顿-格利克尔分期的进展，骨密度会增加。大多角骨的骨密度与桡骨的骨密度之间仅存在中度相关性。
