Inclusion Criteria
- Patients scheduled for epidural nerve block for lower back pain
- Patients over 21 years of age
- Back pain lasting more than 6 months
- Patients with ineffective or insignificant effects of conventional drugs and nerve block for back pain
- Patients with spinal stenosis or disc herniation at the lumbar 4-5 or lumbar 5-sacral 1 level on MRI, and the cross-sectional area of the multifidus muscle at the lesion site is less than 5 cm2 when measured by ultrasound.
Exclusion Criteria

- If lower back pain has rapidly worsened within the last week
- If you have other diseases that may cause low back pain: osteoarthritis of the hip joint, cancer, inflammatory arthritis, spondylitis, fibromyalgia, complex regional pain syndrome, herpes zoster, postherpetic neuralgia, etc.
- When a diagnostic epidural nerve block is planned
- In the case of receiving conservative treatment, procedure, or surgery other than oral drugs such as epidural nerve block or proliferation treatment for the treatment of lower back pain within 4 weeks of screening
- When the low back pain assessed by NRS decreased by more than 50% after epidural nerve block in screening
- If back surgery is planned within 3 months of the procedure
- When NRS and ODI measurements cannot be made
- When collagen injection is contraindicated (eg when allergic to swine)
- Pregnant women

Group Intervention Description Atelocollagen group (atelocollagen group) After obtaining informed consent for the study, epidural nerve block was performed. The patient is asked to return to the outpatient clinic of the pain center after 2 weeks. At this time, when the NRS of back pain does not improve by more than 50% compared to before the epidural nerve block and the cross-sectional area of the multifidus muscle using ultrasound is 5 cm2 or less, final enrollment is decided. The evaluation of the cross-sectional area and thickness of the multifidus muscle using ultrasound is performed with the patient prone, and the cross-sectional area of the multifidus muscle is measured at the same position as the level of the lesion on MRI.
- Primary Outcome Measures
Name Time Method cross-sectional area of the multifidus muscle 28 days after atelocollagen injection Changes in the cross-sectional area of the multifidus muscle at the 4th week of the intervention compared to before the intervention (measured value using ultrasound at outpatient).
- Secondary Outcome Measures
Name Time Method numeric rating score 28 days after atelocollagen injection numeric rating score, Score range from 0 to 100. Higher scores mean a worst outcome.
oswestry disability index 28 days after atelocollagen injection oswestry disability index, Score range from 0 to 50. Higher scores mean a worst outcome.
