Cauda equina syndrome in lumbar disc disease

Area of Science:

• Neurosurgery
• Orthopedic Surgery
• Spinal Disorders

Background:

• Cauda equina syndrome (CES) is a rare but serious condition resulting from compression of the nerve roots in the lumbar spine.
• Lumbar disc herniation is a common cause of low back pain, but its role in causing CES is variable.

Purpose of the Study:

• To investigate the causes of cauda equina syndrome in patients with lumbar disc disease.
• To evaluate the effectiveness of wide laminectomy with facet joint excision for treating CES secondary to lumbar disc herniation.

Main Methods:

• Retrospective analysis of 42 patients diagnosed with lumbar disc disease and CES.
• Surgical intervention involved wide laminectomy, excision of overhanging facet joints, and adequate visualization of lumbar nerve roots.

Main Results:

• Pure disc herniation caused CES in only 5 out of 42 patients.
• Associated structural lesions were identified in 37 patients; operative trauma contributed in 2 cases.
• 95% of patients achieved good to excellent outcomes, with 5% reporting fair results post-surgery; no spinal instability or significant morbidity was noted.

Conclusions:

• Cauda equina syndrome in lumbar disc disease frequently involves factors beyond simple disc herniation, such as associated structural lesions.
• Wide laminectomy with facet joint excision is an effective surgical approach for CES, providing significant symptom relief and excellent long-term results without instability.
