Meralgia Paresthetica When Perineural Steroid Injection Has Not Achieved Complete Symptom Resolution
Clinical Scenario
Patients with meralgia paresthetica in whom the first-line approach — ultrasound-guided perineural steroid injection of the lateral femoral cutaneous nerve — has not resulted in complete resolution of symptoms by 2 months. This protocol addresses the next escalation step.
Prior Treatment — Insufficient Response
The prior therapy — ultrasound-guided perineural steroid injection of the lateral femoral cutaneous nerve — did not meet its target of complete resolution of meralgia paresthetica symptoms at 2 months. Escalation to the next step is indicated.
Next Step — Partial Overview
When injection-based management is insufficient, a neurolytic intervention directed at the lateral femoral cutaneous nerve is the recognised next approach. Both surgical and minimally invasive techniques exist within this category, with the goal of achieving relief of pain in the lateral thigh. The specific method, procedural details, and decision criteria are in the full structured protocol.

- Where these strategies fail, surgical options such as decompression, radiofrequency ablation or neurectomy are suitable for the majority of remaining patients.
- In surgical management strategies, there exists a hierarchy in which neurolysis strategies remain considered less invasive than neurectomy.
- In the first type, an incision for the infra-inguinal approach was made 3 cm below and parallel to the inguinal ligament down to the fascia lata.
- An initial 2% lidocaine injection was delivered followed by radiofrequency ablation at 80º for 180 s in lesion mode.
- Morimoto et al. [26] assessed pain relief and mean VAS pain scores in 12 patients undergoing decompression surgery, of whom 9 reported complete relief and 3 reported partial relief at final follow-up.
