Abstract

Objectives: To evaluate the efficacy of ultrasound (US)-guided injections around the lateral femoral cutaneous nerve (LFCN) at different levels in meralgia paraesthetica (MP) patients. Methods: The study was approved by the university ethics committee and informed oral and written consent were obtained from all patients. Between June 2008 and August 2013, 20 patients with symptoms of MP, including nine men (mean age, 61.33 years) and 11 women (mean age 61.18 years), were treated with US-guided injection of steroids along the LFCN at three different levels in a mean of 2.25 sessions. A visual analogue scale (VAS) was used to measure symptoms before, immediately after and 12 months after treatment. Results: Complete resolution of symptoms was documented in 15/20 patients (mean VAS decreased from 82 to 0), and partial resolution in the remaining five (mean VAS decreased from 92 to 42), which was confirmed at 12-month follow-up. By using the different levels of injection approach overall significantly better symptom relief was obtained (p <0.05). Conclusion: The outcome of US-guided injection along the LFCN can be further improved by injections at different levels (p <0.05), which was confirmed at 12-month long-term follow-up. Key Points: • Meralgia paraesthetica is an entrapment neuropathy of the lateral femoral cutaneous nerve. • Ultrasound proved effective in diagnosis and in guiding injection therapy. • Injection at the anterior superior iliac spine has been used previously. • Multiple injections along the nerve course were used in this study. • Long-term follow-up (12 months) confirmed the results.
