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.
How do you treat a sural nerve injury?
If you are diagnosed with sural neuritis, your podiatrist may develop a course of treatment that includes desensitizing the nerve through massage, medications, corticosteroid injections, and specific footwear to offload pressure on the nerve and reduce irritation.
How long does it take for sural nerve to heal?
Among the three nerve-injury groups, sural nerve recovery was slowest, with the presence of painful neuromas in its innervation zone. However, sensation in the above cutaneous nerve injury region gradually recovered to normal by 6 months to 1 year after surgery.
How do you test for sural nerve damage?
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.
Can the sural nerve regenerate?
In doing so, the sensory nerve ending can regenerate along the length of the motor nerve, giving it a place to go and something to do. In this report, we describe our technique specifically for targeted muscle reinnervation of sural nerve neuromas that is applicable to both amputees and to patients with intact limbs.
What muscles does the sural nerve innervate?
The sural nerve does not innervate any muscle groups as it only provides sensory innervation of the skin. It does, however, travel subcutaneously between the two heads of the gastrocnemius.
What does nerve damage in ankle feel like?
Symptoms of foot and ankle neuropathy and nerve entrapment depend on the cause, but the most common symptoms include: Numbness. Sharp or burning pain. Tingling sensations or feeling that your foot has fallen “asleep”
Can nerve damage heal on its own?
They can repair themselves if the injury is not too severe. Damage to nerves can be severe. Because of their structure and function, nerves do not heal as quickly as some body parts do, but sometimes nerve damage can heal on its own.
What does sural nerve pain feel like?
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.
What is sural neuropathy?
Sural neuropathy, also known as sural nerve entrapment, can be the result of nerve compression or traction injury of the sural nerve.
What is sural nerve entrapment?
Sural nerve entrapment was first described in 1974 [1]. The SN (also known as the short saphenous nerve) is a sensory nerve that can be entrapment in different locations, causing pain in the calf as well as the lateral ankle and foot.
What causes sural nerve entrapment?
Entrapment of the nerve could be caused by compression due to fascial thickening, while the symptomatology includes sensory alterations and deficits at the nerve distribution area. We report a cadaveric case of a variant sural nerve that presented a distinct entrapment site.
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.
What does sural nerve mean?
The sural nerve is a sensory nerve of the lower limb that supplies the lower posterolateral part of the leg and lateral part of the dorsum of the foot. It is generally described as a sensory nerve but may contain motor fibres (discussed later in this article) (14-16). Medial vs. lateral
Where is the sural nerve located?
Your sural nerve runs down the back of your leg, behind the outside edge of your ankle and down the outside of your foot. It provides sensation to those areas and to your two outside toes, and problems can occur if the nerve is irritated or damaged. Below, we take a closer look at why your sural nerve can become damaged, and how it is treated.
