<span style="font-size:14px;"><strong>Carpal Tunnel Syndrome (CTS)</strong></span></p>
<p>
</p>
<p>
The hallmark of classic CTS: pain or paresthesia (numbness and tingling) in a distribution that includes the median nerve territory, with involvement of the first three digits and the radial half of the fourth digit.</p>
<p>
The symptoms of CTS are typically worse at night and often awaken patients from sleep.</p>
<p>
Fixed sensory loss is usually a late finding</p>
<p>
Involves the median-innervated fingers BUT spares the thenar eminence.</p>
<p>
This pattern occurs because the palmar sensory cutaneous nerve arises proximal to the wrist and passes over, rather than through, the carpal tunnel.</p>
<p>
Consider a more proximal lesion in cases involving sensory loss in the thenar eminence</p>
<p>
Example: pronator syndrome</p>
