in pain. Since the majority of the patients were treated for FBSS, this 
article supports the use of SCS for the treatment of FBSS.
In this study, one patient required a revision because of electrode frac-
ture. One patient required removal of the system due to local infec-
tion. One patient required replacement of the IPG due to mechanical 
failure. Overall, 16 of 27 (59%) patients required a total of 36 reposi-
tioning procedures. 
A retrospective analysis performed by Hassenbusch SJ et al. 1995 
included patients with chronic lower body pain, predominately neuro-
pathic pain and pain either midline lower back and/or unilateral or 
bilateral leg pain treated over a 5 year period. The study was a com-
parison of SCS to spinal infusion of opioids. For patients with radicu-
lar pain involving one leg with or without unilateral buttock pain, a 
trial of SCS was recommended first. For patients with midline back 
pain and /or bilateral leg pain, a trial of long-term spinal infusion was 
recommended first. If the patients failed screening with either of these 
modalities, the other was then tested. If the treatment reduced the pain 
by 50%, the systems were internalized. A retrospective analysis of 
patients with unilateral leg and/or buttock pain treated initially with 
SCS and bilateral leg or mainly low back pain treated initially with 
spinal infusions of opioids was then done.
In this study, 42 patients were screened; 26 (62%) patients received 
spinal stimulation; 16 (38%) received opioids via a spinal infusion 
pump. Five patients did not receive adequate pain relief with SCS; 3 
(7%) of these patients underwent trial spinal infusions and had effec-
tive pain relief. There were 4 (10%) patients who underwent a trial of 
spinal infusion of opioid but did not receive adequate pain relief; 
these patients were not tested with SCS. Pain severity was rated using 
a verbal digital pain scale: “On a scale of 0 to 10 where 0 is no pain 
and 10 is the worst pain you could ever imagine, what is your pain 
now?” 16/26 patients (62%) had greater than 50% pain relief with 
SCS. In this study, 2/16 (13%) had greater than 50% pain relief with
