Clinical and electromyographic evaluation after chemonucleolysis for lumbar disk disease

Area of Science:

• Neurosurgery
• Orthopedics
• Pain Management

Background:

• Lumbar disk disease is a common cause of back pain.
• Chemonucleolysis offers a minimally invasive treatment option.

Purpose of the Study:

• To evaluate the clinical and electrophysiological outcomes of chemonucleolysis for lumbar disk disease.
• To assess the efficacy of chemonucleolysis in patients with and without prior surgical history.

Main Methods:

• Clinical evaluation by surgeons (excellent, good, fair, unimproved) at 6-30 months post-procedure.
• Repeat electromyography (EMG) by a physiatrist at ≥3 months post-procedure to assess objective changes.
• Correlation analysis between clinical and EMG findings.

Main Results:

• 91% of 'clean' cases (no prior surgery) and 53% of cases with prior surgery had excellent or good clinical outcomes.
• Objective EMG showed improvement in 90.5% of 'clean' cases and 85.4% overall.
• No patients experienced clinical worsening post-treatment.

Conclusions:

• Chemonucleolysis demonstrates high efficacy in treating lumbar disk disease, particularly in treatment-naïve patients.
• Clinical outcomes closely correlate with objective EMG findings, validating the treatment's effectiveness.
