Surgical treatment for idiopathic meralgia paresthetica showed poor outcomes when symptoms persisted over 18 months. Reoperation offered no benefit if initial nerve decompression failed to relieve pain.

Area of Science:

  • Neurology
  • Surgical Anatomy

Background:

  • Meralgia paresthetica is a condition causing thigh numbness and pain.
  • Idiopathic cases often involve compression of the lateral femoral cutaneous nerve.

Purpose of the Study:

  • To evaluate surgical treatment outcomes for idiopathic meralgia paresthetica.
  • To identify factors influencing treatment success.

Main Methods:

  • Surgical decompression of the lateral femoral cutaneous nerve was performed on 25 patients (14 men, 11 women).
  • Patient demographics and symptom duration were recorded.
  • Outcomes were assessed based on symptom relief post-surgery.

Main Results:

  • Surgical treatment was unsatisfactory in patients with symptoms exceeding 18 months.

  • Reexploration provided no therapeutic benefit in cases with initial decompression failure.
  • Anatomical variations in nerve course may predispose to compression.
  • Conclusions:

    • Early surgical intervention is crucial for successful meralgia paresthetica treatment.
    • Anatomical considerations of the lateral femoral cutaneous nerve are important for surgical planning.
    • Symptom duration significantly impacts surgical outcomes.
