Spinal cord stimulation: A 20-year retrospective analysis in 260 patients
Neuromodulation, 07/01/09

Reig E et al. – Findings show the utility over time of spinal cord stimulation (SCS) is comparable with other series of the efficacy of SCS, with overall analgesic efficacy of ~65%; however, therapy had some complications. Most study pts had a diagnosis of peripheral vascular disease (PVD), with excellent therapy results (>90% improvement), suggesting that SCS be considered as a first-line approach to the clinical management of pts with pain and ulcer of PVD.

• Retrospective review of 20-yr experience with pts receiving SCS implants
• Analysis of data by pain type and group

• Inclusion of 260 pts: 140 men and 120 women

• CRPS group, mean visual analog scale (VAS): 77.89 ± 13.38
• CRPS group, pain relief: 5% no pain relief, 40% poor, 47.5% good, 7.5% excellent
• FBSS group, mean VAS: 79.62 ± 11.69 mm
• FBSS group, pain relief: 13.80% no pain relief, 35.39% poor, 50.76% good, none had complete pain relief
• PVD group, mean VAS: 69.75 ± 14.36 mm
