Open Midline Decompression with Ligament Reconstruction for Multiple-Level Spinal Stenosis in Elderly Patients

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Geriatric Medicine

Background:

• Multiple lumbar spinal stenosis (LSS) is a growing concern in aging populations.
• Traditional multilevel fusion surgery poses significant risks for elderly patients, particularly those with osteoporosis.
• Open midline decompression (OMD) with ligament reconstruction emerges as a less burdensome alternative.

Purpose of the Study:

• To evaluate the efficacy and safety of OMD with ligament reconstruction for elderly patients with multilevel LSS.
• To assess clinical and radiological outcomes following this surgical technique.
• To establish OMD with ligament reconstruction as a viable surgical option.

Main Methods:

• Retrospective review of 42 elderly patients (≥70 years) with LSS at three or more levels.
• Analysis of pre- and postoperative clinical (VAS, SF-12) and radiological data.
• Surgical procedure involved open midline decompression and artificial ligament reconstruction.

Main Results:

• Significant improvements in pain (VAS) and quality of life (SF-12) were observed post-surgery.
• Postoperative MRI confirmed adequate neural decompression.
• Dynamic X-rays indicated a trend towards improved stability, though not statistically significant.
• Mean operative time was 240 minutes, with a mean blood loss of 282.9 cc.

Conclusions:

• OMD with ligament reconstruction effectively decompresses neural elements while preserving the posterior arch.
• This technique provides soft stabilization using artificial ligaments.
• It represents a safe and effective surgical alternative for elderly patients suffering from multilevel LSS.
