This technique produces values of bone mineral density for the whole cross-sectional area of the metacarpal and for the two cortical edges.
The origin of the metacarpal coordinate system was located on the lateral aspect of the distal end of the third metacarpus.
The radiographs were scanned at the nutrient foramen of the third metacarpal with a video densitometer.
Microdensitometry of the metacarpal bone has also been measured in radiographs, using an aluminium step wedge for calibration.
Denham79 measured cortical bone thickness in radiographs of the second metacarpal and showed that this parameter declined with duration of hemiplegia.
However, their hands were together in front of them, crossing one above the other at the level of the distal radii and ulnae, carpals, or metacarpals.
The metacarpal z-axis, contained in the metacarpal frontal plane, ran from the origin proximally along the long axis of the segment at 908 to the x-axis.
This claimed to have shown that women in the highest quartile of bone density at the distal radius or metacarpal had a two- to three-fold increased risk of breast cancer.
