[Clinical efficacy of spinal cord stimulation for the patients with diabetic foot].

To observe the clinical efficacy of spinal cord stimulation (SCS) in the treatment of diabetic foot (DF). Sixteen patients who were diagnosed with DF and treated with SCS from the Department of Pain Medicine of the First Affiliated Hospital, China Medical University from October 2015 to October 2018 were retrospectively analyzed. Visual analogue scale (VAS), 36-item short form health survey (SF-36), transcutaneous oxygen partial pressure (TcPO) and skin temperature of lower limbs were compared before and after treatment, and the complications were recorded. Among the 16 patients, 14 were equipped with implantable pulse generator (IPG). The VAS scores decreased significantly from 7.5±1.2 before treatment to 2.6±0.8, 2.0±0.7, 1.6±0.6, 1.0±0.9, 0.9±0.9 at 1 day, 1 week, 3 months, 6 months and 12 months after electrode implantation respectively (all 0.05). At 12 months after treatment, the parameters of SF-36 were significantly different from those before treatment (all 0.05). The TcPO was (23±5) mmHg before treatment and (38±6) mmHg at 1 week after treatment, with a statistical difference (0.05), and the temperature of lower limbs increased significantly (<0.05). No serious complications were observed in all patients. SCS can relieve the pain of patients with DF, improve the microcirculation and blood supply of lower limbs, and thus promote the quality of life, with rare serious complications.
