Schematic view of sciatic nerve branches with projections of injured fibers into DRG. The schematic view shows that common peroneal and tibial nerves predominantly originate in the L3 and L4 DRG (red fibers), while the sural nerve mainly originates from the L4 and L5 (blue fibers). SNI, Spared Nerve Injury; SNIv_(cp,t), Spared Nerve Injury variant, sparing common peroneal (cp) and tibial (t) nerves.
