me·di·al su·ral cu·ta·ne·ous nerve

[TA]
arises from the tibial nerve in the popliteal space, passes down the calf between the two heads of the gastrocnemius and unites in the middle of the leg with the communicating branch of the common peroneal to form the sural nerve, distributed to the skin of the distal and lateral surfaces of the leg and ankle.

3) during this approach include the medial sural cutaneous nerve as it runs laterally along the small saphenous vein to innervate skin on the posterior lower leg.
Structures at risk during the posterior approach include the popliteal vein (square), medial sural cutaneous nerve (arrow) as it runs laterally along the small saphenous vein (star), and common peroneal nerve (circle) as it branches off the tibial nerve.

2 Variations in the origin of sural nerve (SN): union of medial sural cutaneous nerve (MSCN) and lateral sural cutaneous nerve (LSCN) (A), Absence of MSCN (B), Absence of LSCN (C).
These plexus are supplied by the median superficial sural artery, which runs in conjunction with the medial sural cutaneous nerve, and a series of two arteries accompanying the lesser saphenous vein3-6.
The following variables were then measured: (1) the distance from the popliteal crease to the bifurcation point of the SN; (2) the angle of the bifurcation point of SN; (3) the distance from the popliteal crease to the bifurcation point of the SN; (4) the depth of the bifurcation point of the SN; (5) the distance from the bifurcation point to the branching point of the medial sural cutaneous nerve (MSCN); (6) the depth of the branching point of the MSCN; (7) the distance from the bifurcation point to the branching point of the lateral sural cutaneous nerve (LSCN); (8) the depth of the branching point of the LSCN (Figs.
PC: popliteal crease, A = bifurcation point, B = the most proximal point of the fibula, C = the angle of the bifurcation point of sciatic nerve (18.7 [+ or -] 3.6[degrees]), D = branching point of medial sural cutaneous nerve, E = branching point of lateral sural cutaneous nerve, F1 = branching point of medial head of gastrocnemius, F2 = branching point of lateral head of gastrocnemius, G = branching point to innervate the deep compartment muscles of the leg, H = branching point to innervate the soleus.
A sensory branch, the medial sural cutaneous nerve, contributes to the sural nerve and innervates the dorsolateral skin of the foot.
