Background & Aims
Superior cluneal nerve (SCN) entrapment may be a source of low back pain which remains undiagnosed many times; in this clinical study we have evaluated the efficacy of lidocaine injection of SCN in patients with possibility of SCN entrapment.
Methods
The present study was a prospective, observational study; 30 patients with unilateral low back pain over the iliac crest and buttock for more than six months not responding to conservative measures were included in this clinical trial. SCN lidocaine injection was done under fluoroscopy guidance; patients having more than 50% reduction in NRS scores, for at least 2 hours following SCN injection, were enrolled in the study and followed for 12 months. The primary outcome measure was severity of low back pain, measured by numeric rating scale (NRS) score. Secondary outcome measures were percentage pain relief; Oswestry Disability Index (ODI) score, reduction of analgesic usage, DSM-IV score for psychological assessment. All these assessments were done prior to the procedure and at 2 weeks, 1, 3, 6 and 12 months after the procedure.
Results
We observed significant reduction in the NRS scores at 2 weeks, 1, 3, 6 and 12 months after SCN lidocaine injection as compared to the baseline (P value < 0.05); majority of study participants had significant pain relief and significantly reduced ODI scores, analgesic consumption and DSM scores compared to the baseline (P value < 0.05).
Conclusions
Superior cluneal nerve block provided significant pain relief in low back pain patients with SCN entrapment.
