A modified minimally invasive surgery (MIS) technique for far lateral lumbar discectomy (FLDH) avoids bony drilling, reducing postoperative pain and spinal instability risks. This approach effectively treats extra-foraminal nerve root compression with high symptom resolution rates.

Area of Science:

  • Neurosurgery
  • Spinal Surgery
  • Minimally Invasive Techniques

Background:

  • Far lateral lumbar discectomy (FLDH) addresses extra-foraminal nerve root compression, accounting for 10% of lumbar disc herniations.
  • Advanced imaging increases recognition of FLDH, necessitating effective surgical decompression techniques.
  • Minimally invasive spine surgery (MIS) is increasingly utilized, involving varying degrees of bone removal for nerve root decompression.

Purpose of the Study:

  • To evaluate a modified MIS technique for FLDH designed to minimize bony drilling.
  • To assess the impact of this modified technique on postoperative pain and spinal stability.
  • To determine the efficacy of the technique in achieving symptom resolution for patients with far lateral lumbar disc herniations.

  • Retrospective cohort technical review of patients undergoing MIS FLDH between 2010 and 2020.
  • Analysis of cross-sectional summary statistics, including patient demographics and clinical outcomes.
  • Calculation of descriptive statistics for categorical and continuous variables.

Main Results:

  • A total of 48 patients underwent the modified MIS FLDH, with a mean age of 63 years.
  • The most common symptom was low back and radicular pain (79.2%), with 8.3% experiencing preoperative motor weakness.
  • 93.5% of patients experienced symptom improvement, and 58.7% achieved complete resolution within an average of 2.6 months.

Conclusions:

  • The modified FLDH technique provides MIS access to extra-foraminal compression without bony drilling.
  • This approach effectively minimizes postoperative pain and reduces the risk of iatrogenic spinal instability.
  • The technique achieves significant symptom resolution without compromising patient outcomes.
