Summary
A stingray barb caused tarsal tunnel syndrome in a teen. Electrodiagnostic (EDX) testing identified nerve injury, and surgery successfully removed the barb, leading to symptom resolution.
Area of Science:
- Neurology
- Toxicology
- Orthopedic Surgery
Background:
- Stingray envenomation can cause localized neurotoxicity and trauma.
- Tarsal tunnel syndrome is a condition characterized by compression of the tibial nerve within the tarsal tunnel.
Observation:
- A 17-year-old male presented with symptoms suggestive of tarsal tunnel syndrome following a stingray encounter.
- Initial electrodiagnostic (EDX) evaluation indicated moderate axonal injury within the tarsal tunnel.
Findings:
- Surgical exploration revealed a retained stingray barb within the tarsal tunnel.
- Post-operative recovery showed significant symptom improvement within five weeks.
Implications:
- This case highlights the importance of considering stingray envenomation in the differential diagnosis of lower extremity nerve injuries.
- Electrodiagnostic testing is crucial for diagnosing and managing nerve injuries in the tarsal tunnel.
- Prompt surgical intervention can lead to favorable outcomes in cases of retained foreign bodies causing nerve compression.
