Gastrocnemius muscle herniation at the knee causing peroneal nerve compression resembling sciatica

J Alhadeff1, C K Lee

Summary

Gastrocnemius muscle herniation in the popliteal area can cause peroneal nerve compression, mimicking sciatica. Surgical repair of the torn fascia resolved the pseudoradicular symptoms.

Area of Science:

  • Neurology
  • Orthopedic Surgery
  • Anatomy

Background:

  • Lower extremity nerve compression can present as sciatica (pseudoradiculopathy).
  • Existing literature lacks reports of pseudoradiculopathy caused by gastrocnemius muscle herniation in the popliteal region.

Observation:

  • A case report details a patient with common peroneal nerve compression due to gastrocnemius muscle herniation.
  • The herniation occurred through the gastrocnemius muscle fascia in the popliteal area, causing sciatica-like symptoms.

Findings:

  • Diagnosis was confirmed during exploratory surgery after ruling out lumbar spine causes like disc herniation.
  • Repair of the torn gastrocnemius fascia led to complete symptom relief.

Implications:

Related Experiment Videos

  • This case highlights an unusual cause of pseudoradiculopathy.
  • It suggests gastrocnemius muscle herniation should be considered in the differential diagnosis of lower extremity nerve compression syndromes.
