掌骨形态测量是一种潜在的廉价和广泛使用的骨骼状态的非侵入性评估。在两项横断面研究中，我们比较了半自动技术（帝人Bonalyzer）与内部手动测量的性能特征，以及其他部位的骨骼强度测量。用帝人Bonalyzer和数字化平板电脑测量了178名女性桡骨远端骨折患者的手部X线片的掌骨皮质指数（mCI）。除mCI外，后者的测量值始终低于Bonalyzer（0.443 +/- 0.080 vs 0.364 +/- 0.060，p
Metacarpal morphometry represents a potentially cheap and widely available non-invasive assessment of skeletal status. In two cross-sectional studies, we compared the performance characteristics of a semi-automated technique (the Teijin Bonalyzer) with an in-house manual measurement, and with measures of skeletal strength at other sites. The metacarpal cortical index (mCI) was measured on hand radiographs of 178 osteoporotic women using both the Teijin Bonalyzer and a digitizing tablet. Measurements on the latter were consistently lower than with the Bonalyzer except for mCI (0.443 +/- 0.080 vs 0.364 +/- 0.060, p
