Peripheral nerve stimulation (PNS) has emerged as a promising therapy for CLBP, including SCN. This case series presents the outcomes of six patients with SCN treated with temporary PNS. <h3>Methods</h3> Retrospective analysis of six patients implanted with the Micro Lead -SPRINT PNS System. Data included pain scores, opioid use, complications, and outcomes. <h3>Results</h3> Patients experienced chronic SCN pain for a mean duration of 18 months before PNS. Various treatments were unsuccessful. PNS resulted in significant pain relief and functional improvement at 6 months follow-up. However, at the 2-year follow-up, it was challenging to contact the patients, given inconclusive results. <h3>Conclusions</h3> SCN entrapment is often overlooked as a cause of low back pain. Diagnosis requires a detailed history and physical exam. PNS has shown effectiveness in managing chronic pain conditions and provides an alternative when conservative treatments fail. PNS can be effective in managing SCN, leading to significant reductions in pain intensity and improvements in functional status. However, further research is needed to better understand the optimal patient selection criteria, long-term efficacy, and cost-effectiveness of PNS compared to other treatment modalities.
