Sural nerve
Encyclopedia
The sural nerve formed by the junction of the medial sural cutaneous with the peroneal anastomotic branch of the lateral sural cutaneous nerve
, passes downward near the lateral margin of the tendo calcaneus, lying close to the small saphenous vein
, to the interval between the lateral malleolus and the calcaneus.
It runs forward below the lateral malleolus, and is continued as the lateral dorsal cutaneous nerve
along the lateral side of the foot and little toe (via a dorsal digital nerve), communicating on the dorsum of the foot with the intermediate dorsal cutaneous nerve
, a branch of the superficial peroneal.
In the leg, its branches communicate with those of the collateral branches off of the common tibial, and common fibular nerve.
, as well as the donor nerve when a nerve graft is performed.
Lateral sural cutaneous nerve
The lateral sural cutaneous nerve supplies the skin on the posterior and lateral surfaces of the leg. The lateral sural cutaneous nerve originates from the Common fibular nerve.One branch, the peroneal anastomotic The lateral sural cutaneous nerve (lateral cutaneous branch) supplies the skin on...

Small saphenous vein
The small saphenous vein , is a relatively large vein of the superficial posterior leg.-Path:Its origin is where the dorsal vein from the fifth digit merges with the dorsal venous arch of the foot, which attaches to the great saphenous vein...

Intermediate dorsal cutaneous nerve
The intermediate dorsal cutaneous nerve , the smaller, passes along the lateral part of the dorsum of the foot, and divides into dorsal digital branches, which supply the contiguous sides of the third and fourth, and of the fourth and fifth toes.It also supplies the skin of the lateral side of the...

In the leg, its branches communicate with those of the collateral branches off of the common tibial, and common fibular nerve.
Clinical significance
It is often used for nerve biopsyNerve biopsy
In medicine, a nerve biopsy is an invasive procedure in which a piece of a nerve is removed from an organism and examined microscopically. A nerve biopsy can lead to the discovery of necrotizing vasculitis, amyloidosis, sarcoidosis, leprosy, metabolic neuropathies, inflammation of the nerve, loss...
