Spinal cord stimulation (SCS) is considered a minimally invasive and reversible neuromodulation therapy for various chronic pain disorders. The rates of infection following SCS surgery reported in the literature range from 2.8% to 10%. Several studies indicated no potential benefit of postoperative antibiotics (beyond 24 hours) on subsequent device infection. This study aimed to understand the characteristics of postoperative antibiotic prescriptions and subsequent infections following SCS surgery. ⋯ Prospective studies are needed to understand the reasons for noncompliance with expert consensus recommendations on postoperative antibiotic use beyond 24 hours of SCS surgery. Neuromodulation team members should play an important role in antibiotic stewardship.

Spinal cord stimulation (SCS) has become a popular nonopioid pain intervention. However, the treatment failure rate for SCS remains significantly high and many of these patients have poor sagittal spinopelvic balance, which has been found to correlate with increased pain and decreased quality of life. The purpose of this study was to determine if poor sagittal alignment is correlated with SCS treatment failure. ⋯ This retrospective cohort analysis of SCS patients did not demonstrate any relationship between poor sagittal alignment and failure of SCS therapy. Further studies of larger databases should be performed to determine how many patients ultimately go on to have additional structural spinal surgery after failure of SCS and whether or not those patients go on to have positive outcomes.

Paddle leads for spinal cord stimulation (SCS) offer more efficient energy delivery and advantages in some patients. However, there is concern for how safely SCS paddles can be replaced once previously implanted because of scar tissue and the relative vulnerability of the thoracic cord. In this study, we share our experience on SCS paddle replacement. ⋯ This study characterizes the safety profile of SCS paddle replacement surgeries. Here, we demonstrate that the replacement of paddle leads at the time of removal, with additional lamina removal if needed because of scar, is associated with low rates of complications. This validates the feasibility and low-risk profile of replacing paddle leads when clinically indicated for experienced surgeons with specialization in SCS.

Spinal cord stimulation (SCS) is a surgical treatment modality reserved for a subset of patients with neuropathic pain in which conventional pharmacologic treatment has proven insufficient. Previous studies have suggested a possible negative relationship between opioid use at referral and subsequent success of SCS therapy. The aim of this cohort study was to investigate whether preoperative opioid use was associated with inferior SCS outcomes. ⋯ Preoperative opioid usage did not predict the outcome of SCS therapy in a large cohort of patients permanently implanted with an SCS system. The results do not support withholding otherwise well-indicated SCS therapy in patients with chronic neuropathic pain conditions based merely on preoperative opioid usage.
