239. Joints <strong>of</strong> the right hand, articulatio manus,<br />
viewed from the back <strong>of</strong> the hand.<br />
Articulatio manus (continuation). On the dorsal surface, tlie capsule <strong>of</strong> the articu-<br />
latio radiocarpea is strengthened by the ligamentum radiocarpeum dorsale (0. T. posterior<br />
ligament) which goes from the dorsal margin <strong>of</strong> the facies articularis carpea radii in different<br />
divisions to the bones <strong>of</strong> the first row <strong>of</strong> the carpus,<br />
The articulatio intercarpea possesses on the dorsal surface several short strengthening ligaments,<br />
lir/amenta intercarpea dorsalia (0. T. dorsal ligaments), which run usually transversely.<br />
The articulationes carpometacarpeae (carpometacarpal articulations) are formed on the<br />
one side by the distal surfaces <strong>of</strong> the bones <strong>of</strong> the second row <strong>of</strong> the carpus, on the other<br />
side by the proximal surfaces <strong>of</strong> the ossa metacarpalia. Several short perpendicular and oblique'<br />
ligaments on the volar and dorsal surfaces, ligamenta carpometacarpea dorsalia et volana<br />
(0. T. dorsal and palmar hgaments) serve to their capsulae articulares as strengthening ligaments<br />
<strong>of</strong> the latter, that situated furthest ubiarward extends from the hamulus ossis hamati to the<br />
basis ossis metacarpalis V and is called the ligamentum hamatometacarpeum (see Fig'. 238).<br />
The articulationes intermetacarpeae (articulations <strong>of</strong> the metacarpal hones with one<br />
another) have their origin in that the proximal ends <strong>of</strong> the second to the fifth metacarpal<br />
bones can move upon one another by means <strong>of</strong> their lateral surfaces which are covered with<br />
cartilage. Their capsulae ariiculares are strengthened by short transversely directed fibre<br />
bands, ligamenta basium [ossium metacarpalium] dorsalia et volaria <strong>of</strong> which there are four<br />
on the back <strong>of</strong> the hand, but only three in the hollow <strong>of</strong> the hand (the ligament between the<br />
OS metacarpalo I and II is absent) (see also Kg. 238).<br />
