What does the lateral sural nerve innervate?
The sural nerve passes distally close to the short (or lesser) saphenous vein, passing approximately 1–1.5 cm behind the lateral malleolus. It innervates the lateral aspect of the little (fifth) toe.
What happens if the sural nerve is damaged?
Damage or compression of the sural nerve can result in burning pain and diminished sensation or loss of sensation (numbness). This nerve passes down from the back of the knee along the outside of the lower leg. It’s located along the surface of the lower one-third of the leg.
What causes sural nerve neuropathy?
Sural neuritis (a.k.a. sural neuralgia) is pain that occurs due to irritation or injury of the sural nerve. The pain is typically described as a burning sensation located on the outside of the foot and ankle. It may occur following surgery of the foot and ankle or after a direct injury to the nerve itself.
Where does sural nerve get entrapped?
Entrapment involving the sural nerve typically occurs at the musculotendinous junction of the gastrocnemius muscle and the Achilles tendon within the calf, as the nerve travels through a fibrous arcade (which has been termed the “superficial sural aponeurosis”)  (Fig. 71.9a), at the ankle (Fig.
What does the sural nerve control?
The sural nerve, a sensory nerve, courses down the postural-lateral aspect of the calf. Its primary role is to innervate the skin over the distal one third of the lateral shin and outside of the foot towards the fifth toe.
How long does it take sural nerve to heal?
Sural nerve sensation began to recover at 3 months after surgery, but there were no cases of complete recovery of sural nerve sensation. However, superficial peroneal nerve function had returned to normal in a few cases, and saphenous nerve sensation had recovered to normal or close to normal levels in most cases.
What does sural nerve do?
The sural nerve is a cutaneous nerve, providing only sensation to the posterolateral aspect of the distal third of the leg and the lateral aspect of the foot, heel, and ankle.
What is the function of the sural nerve?
Function. The sural nerve is purley sensory and it supplies sensation to the lower lateral leg, lateral heel, ankle and doral lateral foot.
What causes damage to the sural nerve in the foot?
The sural nerve is purely sensory and it supplies sensation to the lower lateral leg, lateral heel, ankle and dorsal lateral foot. Damage to the sural nerve due to injury can occur as a result of trauma, fractured calcaneus, damage from surgery in the region.
Where is the medial sural cutaneous nerve located?
Medial sural cutaneous nerve, communicating branch with the common fibular nerve (S1, S2) Innervates. Supplies sensation to the skin of the lateral foot and lateral lower ankle.
Is it easy to block the sural nerve?
Sural nerve block. The sural nerve is rather superficial, which makes it more accessible to surgeons. Therefore, it is relatively easier than other procedures. Also, due to its superficial properties, the sural nerve is easily blocked at multiple levels at or above the ankle. In one study, regional anesthesia of the foot and ankle,…
