Sural Nerve Entrapment

Sonographic imaging and assessment of the sural nerve

“…Clinical examination has been historically considered the principle method of diagnosis of sural nerve neuropathies. 11 Differential diagnoses such as sciatic radiculopathy, common peroneal or tibial nerve pathology, compartment syndrome of the lower limb, popliteal artery entrapment and Achilles tendinopathy may, however, present with similar symptoms. 12 The sural nerve neurodynamic test can be performed to replicate clinical symptoms experienced by the patient.…”

Ultrasound-guided hydrodissection of sural nerve for foot pain- A case report

“…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), at the ankle or in the lateral foot near the base of the fifth metatarsal. (6) The tension is worsened during passive forcible plantar flexion and inversion of the foot increases tension in the sural nerve as the nerve is tightly adherent to the surrounding fascia. (7) Entrapment of the sural nerve can also be due to post-traumatic scar tissue beneath the deep fascia of gastrocnemius, peroneal nerve sheath degeneration, calcaneocubiod joint capsule degeneration and Achilles tendonitis.…”

Surgical treatment is required when the removal of space-occupying masses (ganglion/lipoma) is necessary.…”

Ultrasound-guided Hydrodissection of Sural Nerve for Foot Pain

“…The sural nerve can become ensnared anyplace along its course in the lower limit. Ensnarement including the sural nerve normally happens at the musculotendinous intersection of the gastrocnemius muscle and the Achilles ligament inside the calf, as the nerve goes through a sinewy arcade (named the superficial sural aponeurosis), at the ankle or in the lateral foot near the base of the fifth metatarsal [5]. The pressure is deteriorated during passive persuasive plantar flexion.…”
