Summary
Meralgia paresthetica, or lateral femoral cutaneous nerve (LFCN) entrapment, can be treated with nerve transposition. This surgical technique offers effective relief for thigh numbness and pain.
Area of Science:
- Neurosurgery
- Surgical Anatomy
Background:
- Meralgia paresthetica, caused by lateral femoral cutaneous nerve (LFCN) impingement, presents with anterolateral thigh sensory disturbances.
- Traditional surgical options include nerve release or neurectomy.
Purpose of the Study:
- To demonstrate key operative techniques for LFCN transposition.
- To highlight methods for successful nerve identification, decompression, and transposition.
Main Methods:
- Ultrasound-guided wire localization for precise nerve targeting.
- Sequential decompression involving superficial and deep approaches.
- Inguinal ligament release and medial nerve transposition.
Main Results:
- The described techniques facilitate accurate LFCN identification and adequate decompression.
- Medial transposition is presented as a viable surgical solution.
Conclusions:
- LFCN transposition is an effective surgical approach for meralgia paresthetica.
- Mastery of these operative steps ensures optimal patient outcomes.
