MATERIALS AND METHODS<br />
The Poole-Rose skeletal material was sorted, washed, and<br />
catalogued by pr<strong>of</strong>essors and students at Louisiana State<br />
University, and assigned catalog numbers based on excavation<br />
unit, level, and bone number. The radii which <strong>in</strong>cluded whole<br />
bones, proximal ends, distal ends, and shafts were sorted<br />
accord<strong>in</strong>g to left, right, and undeterm<strong>in</strong>ed sides. Attempts were<br />
made to match fracture l<strong>in</strong>es and reconstruct bones. Adult bones<br />
were analyzed <strong>in</strong> this study. Age and sex were not determ<strong>in</strong>ed.<br />
Adult bone measurements were taken on complete bones us<strong>in</strong>g<br />
an osteometric board. Maximum length was measured from <strong>the</strong><br />
radial head to <strong>the</strong> tip <strong>of</strong> <strong>the</strong> styloid process <strong>in</strong> millimeters<br />
(Bass, 1995). Us<strong>in</strong>g a small, digital slid<strong>in</strong>g caliper, radial<br />
head diameter was also measured <strong>in</strong> millimeters. Comparisons were<br />
made with lengths <strong>of</strong> radii from o<strong>the</strong>r Late Woodland ossuaries.<br />
The articular <strong>jo<strong>in</strong>t</strong> surfaces <strong>of</strong> <strong>the</strong> <strong>radius</strong> were analyzed<br />
for DJD. The head <strong>of</strong> <strong>the</strong> <strong>radius</strong>, which articulates with <strong>the</strong><br />
humerus; <strong>the</strong> distal facet, which articulates with <strong>the</strong> scaphoid<br />
and semi-lunar bones <strong>of</strong> <strong>the</strong> hand; and <strong>the</strong> ulnar notch, which<br />
articulates with <strong>the</strong> ulna, were each evaluated separately for<br />
three types <strong>of</strong> bone lesions suggest<strong>in</strong>g <strong>degenerative</strong> changes.<br />
The radii were seriated accord<strong>in</strong>g to degree <strong>of</strong> degeneration for<br />
