This study introduces a novel lateral laparoscopic approach for spinal fusion, simplifying access to L4-L5 and L5-S1 discs. The technique proved safe and effective, avoiding major vessel dissection and achieving good fusion rates.

Area of Science:

  • Minimally Invasive Spine Surgery
  • Spinal Fusion Techniques
  • Laparoscopic Surgery

Background:

  • Anterior laparoscopic approaches to L4-L5 require difficult dissection near iliac vessels.
  • Retroperitoneal endoscopic approaches to L4-L5 pose technical challenges for L5-S1 access.
  • A novel lateral laparoscopic approach offers concurrent L4-L5 and L5-S1 access, avoiding major iliac vessel dissection.

Purpose of the Study:

  • To describe a novel lateral laparoscopic approach for lumbar disc exposure.
  • To evaluate the initial clinical outcomes of this technique for spinal fusion.

Main Methods:

  • A retrospective review of five patients undergoing laparoscopic lateral L4-L5 disc exposure (Jan 1999-Apr 2000).
  • Utilized a standard five-port laparoscopic technique with medial sigmoid colon retraction.

  • Involved retroperitoneal entry, medial retraction of ureter/left iliac artery, lateral psoas retraction, and fluoroscopy-guided discectomy/cage insertion.

    • Main Results:

    • Five male patients (mean age 47.4 years, BMI 30 kg/m2) underwent the procedure.
    • Mean operative time was 349 minutes with 210 cc blood loss; no intraoperative complications.
    • Mean hospital stay was 3.4 days, return to work averaged 12 weeks; all patients showed fusion, with 80% pain-free at 1 year.

    Conclusions:

    • The lateral laparoscopic approach is safe and effective for multilevel lumbar fusions including L4-L5.
    • This technique provides simultaneous access to multiple disc spaces while preserving critical structures.
    • Offers excellent exposure for precise orthopedic hardware placement.
