The  flexor  carpi  radialis  brevis  is 

a variable muscle, which, if present 

can compress the anterior interos-

seous nerve.

The  pronator,  supinator  and  cu-

bital  canals are narrow spaces be-

tween the muscles of the forearm 

through which the median nerve, 

deep branch of the radial nerve and 

ulnar nerve run, respectively. These 

nerves may be compressed in their 

canals, causing nerve entrapment 

syndromes.
