Abstract
Background: Sural nerve entrapment is an important but infrequent cause of pain. The sural nerve provides sensation to the posterolateral aspect of the leg, lateral foot and fifth toe. Sural nerve entrapment can be challenging to treat and can cause significant limitation. We present a case of sural nerve entrapment resistant to conservative management that was effectively treated by percutaneous ultrasound guided hydrodissection of the sural nerve.
Case Report: A 57 year old male came with complaints of pain and tingling sensation on both lower limbs with 50% decrease in sensation to touch (right > left) in lateral aspect of both foot. The patient had tried several conservative modalities with no success. We performed percutaneous ultrasound guided hydrodissection of the sural nerve and the patient reported complete improvement in his pain.
Conclusion: Percutaneous ultrasound guided hydrodissection of the sural nerve, is a safe and effective treatment for patients with sural nerve entrapment that does not respond to conservative therapy. However, studies are needed to elucidate its effectiveness and safety profile.
