Summary
Late-onset sciatic neuralgia from hamstring injury can be diagnosed with dynamic imaging and treated with minimally invasive ultrasound-guided neurolysis. This approach offers a viable solution for nerve entrapment caused by muscle retraction and scarring.
Area of Science:
- Neurology
- Sports Medicine
- Radiology
Background:
- Hamstring injuries are common in sports, but late-onset sciatic nerve involvement is rare.
- Scarring from chronic hamstring avulsion can lead to nerve entrapment.
Observation:
- A case of late-onset sciatic neuralgia was observed.
- Imaging revealed a retracted hamstring muscle with cicatricial adhesions tethering the sciatic nerve.
Findings:
- Dynamic ultrasound and MRI effectively visualized the sciatic nerve tethering.
- Percutaneous neurolysis successfully treated the sciatic neuralgia.
Implications:
- Dynamic imaging aids in diagnosing rare nerve entrapment syndromes.
- Ultrasound-guided percutaneous neurolysis is a promising minimally invasive treatment for this condition.
