Area of Science:

  • Orthopedics
  • Minimally Invasive Surgery
  • Neuroscience

Background:

  • Piriformis syndrome causes significant patient morbidity, including pain and functional limitations.
  • Traditional open sciatic neurolysis offers temporary relief, with recurrence often linked to scar tissue formation.
  • Existing minimally invasive decompression techniques yield variable outcomes.

Purpose of the Study:

  • To present a detailed, step-by-step surgical technique for minimally invasive piriformis syndrome treatment.
  • To enhance patient safety and surgeon orientation during the procedure.
  • To achieve comprehensive sciatic nerve neurolysis.

Main Methods:

  • Preoperative diagnosis includes retro-trochanteric pain, sciatica, paresthesias, and positive CT-guided injections.
  • The procedure utilizes a lateral decubitus position with two 6-8 cm portals for triangulation.
  • Dissection employs radiofrequency and a laparoscopic peanut, with sciatic nerve control via a vascular sling.

Main Results:

  • The described technique facilitates thorough sciatic neurolysis.
  • Encouraging preliminary results suggest efficacy in treating piriformis syndrome.
  • The method prioritizes patient safety and surgeon orientation.

Conclusions:

  • This minimally invasive technique offers a promising approach for piriformis syndrome management.
  • Detailed technical descriptions and visual aids can aid experienced hip arthroscopists.
  • Further investigation into this procedure's long-term outcomes is warranted.
