Research Progress on the Posterior Midline Lumbar Spinous Process-Splitting Approach

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Spinal Surgery

Background:

• Traditional posterior median approach laminectomy for lumbar decompression often results in paraspinal muscle atrophy and chronic low back pain.
• Minimally invasive techniques are sought to reduce surgical morbidity associated with lumbar decompression.

Purpose of the Study:

• To review the anatomical considerations, surgical techniques, and clinical applications of the posterior midline spinous process-splitting approach (SPSA).
• To highlight the effectiveness of SPSA in reducing muscle atrophy and improving recovery outcomes compared to traditional methods.

Main Methods:

• Review of anatomical considerations for SPSA.
• Description of the surgical technique involving longitudinal splitting of the spinous process.
• Analysis of clinical applications for lumbar spinal stenosis, disc herniation, and spondylolisthesis.

Main Results:

• SPSA minimizes damage to paraspinal muscles, preserving their integrity.
• The approach provides adequate surgical access for decompression without muscle detachment.
• Reduced incidence of muscle atrophy and chronic low back pain observed with SPSA.

Conclusions:

• SPSA is a viable alternative to traditional laminectomy, offering superior muscle preservation and improved recovery.
• Further research is needed to establish long-term benefits and refine SPSA techniques.
• SPSA shows potential for treating various lumbar spine conditions effectively.
