Herniation of the upper lumbar discs

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Neurology

Background:

• Lumbar disc herniations can lead to severe neurological deficits.
• Upper lumbar disc herniations (L1-L4) are associated with more pronounced symptoms compared to lower lumbar levels.
• Accurate localization of the herniation is critical for effective treatment.

Purpose of the Study:

• To analyze the clinical characteristics and surgical outcomes of upper lumbar disc herniations.
• To evaluate the correlation between herniation level and neurological severity.
• To emphasize the importance of diagnostic tools like myelography.

Main Methods:

• Retrospective analysis of 134 patients undergoing surgery for lumbar disc herniations.
• Correlation of herniation level (L1-L4 vs. lower lumbar) with neurological deficits (paresis, autonomic dysfunction).
• Assessment of early and long-term postoperative outcomes, including patient recovery and complications.

Main Results:

• Upper lumbar disc herniations (L1-L4) were linked to significantly higher rates of paresis (50%) and autonomic disturbances (26.9%).
• Cerebrospinal fluid (CSF) protein levels >100 mg% suggested upper lumbar lesions.
• Myelography proved essential for precise level determination.
• Excellent or good early postoperative results were achieved in 124/134 patients, with most regaining mobility.
• Long-term follow-up showed sustained improvement, though 7 patients experienced no change or deterioration.

Conclusions:

• Upper lumbar disc herniations present with more severe neurological deficits.
• Timely surgical intervention and accurate diagnosis (e.g., via myelography) are vital for favorable outcomes.
• While most patients experience significant recovery, a small percentage may have persistent or worsening symptoms.
