Introduction Paddle leads with three parallel electrode arrays (i.e., tripolar leads) are increasingly used for spinal cord stimulation. Preliminary data has suggested that tripolar leads can provide broad paresthesia coverage to patients with concurrent low back and low extremity pain.¹ In this poster, we present the initial outcomes of chronic pain patients who were treated with spinal cord stimulation using an anatomically shaped tripolar lead. Methods Data was collected retrospectively on 8 patients suffering from refractory low back and leg pain who had been implanted with tripolar leads. The data included information on pain relief, paresthesia coverage, and stimulation programming. The tripolar lead had a middle array of six electrodes flanked by two outside arrays of five electrodes each (Fig. 1). The electrodes could be individually controlled to direct the stimulation over the dorsal columns. In cross-section, the lead was contoured to help it conform to the shape of the dura. Results All patients had been diagnosed with failed back surgery syndrome and had pain in the low back, buttocks, and/or legs (Table 1). The majority of patients had axial back pain that extended to the L4 vertebral level. At an average of (info pending) months post-implantation, the patients reported substantial declines in pain (Fig. 2). All but one patient had complete coverage of their pain topography. Programming parameters for the patients varied, as did the location of their electrode combinations on the lead (Fig. 3). Conclusion In this preliminary survey, tripolar leads provided broad paresthesia coverage to patients with low back and lower extremity pain, with pain relief extending as high as the L4 dermatomes.
