Abstract
This study was designed to determine the anatomical sites of radial
nerve compression, and consisted of 30 upper limb specimens dissected
to expose the radial nerve throughout its course through the arm and forearm
and was photographed. The radial nerve was found to be crossed at
least at one site in each specimen, it was found crossed by muscle bundles
in the radial tunnel in 12 specimens (40%) and as it pierces the supinator
muscle in another 12 specimens, (40%) and was found crossed by
vascular elements in 7 specimens (23.33%), in 5 specimens as it traverses
the radial tunnel and in 2 specimens at the cubital fossa. Crossing fibrous
bands were reported in 7 specimens (23.33%) in the radial tunnel.
extending between the brachialis and brachioradialis muscles. We can
conclude that radial nerve is crossed at various sites throughout its
course through the arm and forearm, however, the commonest site being
in the front of the lateral intermuscular septum (at the radial tunnel) and
the commonest crossing element is the muscular bundles. |
