This study aims to evaluate the analgesic efficacy of epidural neuroplasty using a Racz catheter during lumber fixation in situ for lumbosacral spondylolisthesis.

Lumbosacral spondylolisthesis, a common neurosurgical disorder, involves the anterior displacement of a vertebra in relation to the one below it. It often leads to back pain and neurologic symptoms.

Epidural lysis of adhesions is a procedure which treat chronic LBP in patients which didn't respond to medical treatments.The technique of Radiofrequency ablation (RFA) uses high-frequency current to produce tissue coagulation and heat. It involves the use of radio waves, applied through a percutaneous probe to generate heat and create a lesion in a spinal sensory nerve

Inclusion Criteria:

• Age from 18 to 65 years.
• Both sexes.
• Patients suffering from spondylolisthesis grade 0, 1, 2 complaining of low back pain and/or sciatica.

Exclusion Criteria:

• Uncooperative patients.
• Patients in need of discectomy for lumber disc prolapse.
• Patients with severe canal stenosis and in need of spinal laminectomy.
• Contraindications to perform the proper technique e.g., coagulopathy and skin infection.
• Body mass index (BMI) ≥35 kg/m2.
• History of allergy to contrast medium.
• Previously operated traditional spine surgeries.

The data will be available upon a reasonable request from the corresponding author after the end of study for one year.
