Description
The grooves for extensor muscle tendons are the smooth, oblique and vertical depressions found on the posterior aspect of the distal part of radius.
These grooves are divided, by the dorsal radial tubercle, into two groups:
—those that are found medial to the tubercle, the grooves for the tendons of the extensor digitorum, extensor pollicis longus, and extensor indicis muscles;
—those that are found lateral to the tubercle, the grooves for the tendons of the extensor carpi radialis longus and brevis muscles.
