Chronic postsurgical spine pain: Spinal cord stimulation offers benefits

Advanced neuromodulation reduces biological pain intensity in persistent spinal pain syndrome type 2. However, it fails to spontaneously decrease long-term opioid consumption.

Chronic pain following spine surgery remains a challenging clinical problem, requiring treatment strategies that address more than pain intensity alone. A systematic review and network meta-analysis exploring pharmacological, interventional, and rehabilitative approaches found that spinal cord stimulation (SCS) + conventional medical management (CMM) markedly improved the likelihood of attaining substantial pain relief. However, this benefit did not translate into reduced long-term opioid use in a large real-world cohort.

Researchers searched the MEDLINE, Embase, and Cochrane databases for studies issued up to April 15, 2026. Of 1,452 records screened, 100 studies were incorporated in the qualitative synthesis, while 24 randomised controlled trials and high-quality cohort studies contributed to the quantitative meta-analysis. The major findings were:

  • Spinal cord stimulation: SCS + CMM was considerably more effective than CMM alone in attaining greater than 50% pain reduction (odds ratio [OR], 10.32; I² = 68%).
  • Long-term opioid therapy: Real-world data from 12,632 patients exhibited no significant reduction in long-term opioid therapy following SCS implantation compared with matched non-SCS cohorts (OR, 1.05), highlighting a disconnect between pain relief and opioid reduction.
  • Rehabilitative interventions: High-intensity laser therapy and spinal manipulative therapy illustrated remarkable betterment in functional disability, measured using the Oswestry Disability Index (ODI), at 12 months.
  • Systemic health implications: Longitudinal evidence linked persistent spinal pain syndrome type 2 (PSPS-T2) with heightened risks of all-cause mortality, psychiatric ailments, and dementia. The authors suggested that long-term polypharmacy and physical inactivity may contribute to these associations.

The findings support a shift from a predominantly mechanical approach to chronic postsurgical spine pain towards multidisciplinary care that integrates neuromodulation, rehabilitation, medication management, and psychological support. Although SCS can yield substantial pain relief, it must not be assumed to minimize opioid dependence or long-term opioid exposure. The authors emphasised the importance of early functional restoration and a holistic, biopsychosocial approach to treatment, with pain control and opioid reduction addressed as distinct therapeutic goals.
