The results from <strong>the</strong> Poole-Rose population show no significant<br />

statistical relationship between side and any <strong>of</strong> <strong>the</strong> variables,<br />

with <strong>the</strong> exception <strong>of</strong> side and pitt<strong>in</strong>g on <strong>the</strong> proximal <strong>radius</strong>.<br />

The left side <strong>of</strong> <strong>the</strong> proximal <strong>jo<strong>in</strong>t</strong> is affected slightly more<br />

than <strong>the</strong> right side <strong>in</strong> <strong>the</strong> category for m<strong>in</strong>imal pitt<strong>in</strong>g only.<br />

See tables 3.16-3.21 for an evaluation <strong>of</strong> side by <strong>jo<strong>in</strong>t</strong> surface.<br />
