The Thompson (posterior) approach to the radius involves the interval between the radial nerve and the posterior interosseous nerve (a branch of the radial nerve proper). Proximally, the interval is between the ECRB (radial nerve) and the EDC (PIN), whereas more distally, the interval is between the ECRB (radial nerve) and EPL (PIN). The approach can simply be thought of as between the muscles of the mobile wad compartment, and those of the dorsal compartment.
