Where is the sural nerve?
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.
Why sural nerve is selected for biopsy?
Sural nerve biopsy usually represents the conclusive step in the diagnostic work-up of several peripheral neuropathies. It is an invasive procedure, so it is applied only in cases unresolved after an extensive workout; when successful it can modify the subsequent therapeutic choices (5–7).
Why is sural nerve biopsied?
It is clear that sural nerve biopsy has an important place in the diagnosis of peripheral nerve disease and, in the case of vasculitic neuropathy confined to peripheral nerves, it is the only certain way of making the diagnosis of the treatable condition.
How is sural nerve damage treated?
Sural neuralgia is a relatively rare condition and often responds to conservative treatments such as rest, physical therapy, massage therapy, antiinflammatory medications, tricyclic antidepressants, serotonin and norepinephrine inhibitors, gabapentin, and calcium channel blockers.
How is sural nerve damage diagnosed?
Sural nerve neurodynamic test To perform this test, the patient’s leg is grasped by the therapist’s hands so that the leg is supported and the foot is held in dorsiflexion and inversion. The leg is then passively raised into hip flexion. This is usually felt in the posterolateral calf and/or posterolateral ankle.
What can a sural nerve biopsy diagnose?
In effect, this procedure is particularly useful to diagnose interstitial neuropathies, such as vasculitis, granulomatosis, leprosy, amyloidosis or tumors, but also to confirm a chronic inflammatory demyelinating polyneuropathy with atypical presentation (6, 7).
How is a sural nerve biopsy done?
An incision is made, and the lesser saphenous vein is identified. The vein is then retracted superficially to expose the sural nerve. For a complete nerve biopsy, untied sutures are placed into both ends of the nerve, and the nerve is transected above these sutures.
What are the symptoms of sural nerve injury?
Pain and sensory alterations over the distribution area of the nerve (40).
What muscles does sural nerve supply?
The sural nerve descends lateral to the calcaneal tendon, near the short saphenous vein, to the region between the lateral malleolus and the calcaneus and supplies the posterior and lateral skin of the distal third of the leg.
