Clinical Report: Contralateral trans-spinous base inclined technique utilizing AUSS

Overview

This case study presents the contralateral trans-spinous base inclined (CTI) technique utilizing arthroscopic-assisted uni-portal spinal surgery (AUSS) for treating multilevel lumbar lateral recess and foraminal stenosis in a 72-year-old patient. The approach demonstrated effective decompression and preservation of spinal stability.

Background

Lumbar spinal stenosis (LSS) is prevalent among the elderly and can severely affect quality of life. Traditional surgical methods, such as open laminectomy, carry risks including instability and significant blood loss. Minimally invasive techniques like AUSS offer potential advantages in managing complex spinal conditions while minimizing complications.

Data Highlights

No numerical data or trial data provided in the source material.

Key Findings

  • The CTI-AUSS technique was employed in a 72-year-old man with multilevel LSS.
  • Postoperative imaging confirmed effective decompression at L3/4 and L4/5 levels.
  • The average preservation rate of facet joints was 93.97%.
  • The patient experienced immediate postoperative pain relief and neurological improvement.
  • The total operative time for the procedure was 240 minutes.

Clinical Implications

The CTI-AUSS technique may provide a safe and effective surgical option for elderly patients with multilevel lumbar stenosis, minimizing the risk of postoperative instability. Preservation of spinal structures is crucial in maintaining long-term outcomes.

Conclusion

The CTI-AUSS approach demonstrates promising results in treating complex lumbar stenosis while preserving spinal stability and minimizing surgical risks.
