<u><strong>Trapezium Fractures</strong></u></p>
<ul>
<li>
The trapezial body is often fractured due to an axial load through the thumb</li>
<li>
The trapezial ridge is often fractured during a fall on an outstretched hand</li>
<li>
Accounts for 1% to 5% of all carpal fractures.</li>
</ul>
<p>
<strong>Suspect the Diagnosis when you note</strong></p>
<ul>
<li>
Tenderness over trapezium </li>
<li>
Often have increased pain with axial loading of thumb.</li>
<li>
Point tenderness at the volar base of the thumb just distal to the scaphoid, at the base of the first metacarpal.</li>
<li>
Since the trapezium is obscured by superimposed bones in PA and lateral views, fractures are most easily identified on the oblique radiographs</li>
</ul>
<p>
If you are suspected the diagnosis oblique radiographs or a CT scan of the wrist will note the fracture the best.</p>
<p>
<strong>Treatment</strong> consists of placing the patient in a thumb spica splint.</p>
