Back pain breakthrough? study pits two key surgeries against each other
NCT ID NCT07127380
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two minimally invasive spine surgeries (Mini-TLIF and MIDLIF) for people with chronic low back pain from disc disease. 100 adults who haven't improved with other treatments will be randomly assigned to one surgery and followed for a year. The goal is to see which surgery provides better pain relief, fewer complications, and lower costs.

Inclusion Criteria: * Discogenic lower lumbar-sacral pain lasting longer than one year * Failure of conservative treatment, including rehabilitation and pain management * Lumbar discopathy qualified for interbody fusion and pedicle screw stabilization * Informed consent of the patient for the study and proposed treatment Exclusion Criteria: * Contraindications to surgery under general anesthesia * Age \< 18 years * Pregnancy, breastfeeding * Lack of informed consent to participate in the study * Lumbar-sac discopathy requiring surgical treatment at more than two levels * Spinal deformities: adult idiopathic scoliosis, degenerative scoliosis, deformity due to spinal malignancy, inflammatory spinal disease, post-traumatic, or associated with congenital anomalies * Lower lumbar-sacral pain syndrome, which, in the investigator's opinion, has an etiology other than degenerative spine disease (e.g., cancer-related pain, ankylosing spondylitis) * Spinal oncology disease * True and degenerative spondylolisthesis * Contraindications to performing MRI of the lumbar-sacral spine
