A prospective, randomized, controlled trial was conducted to compare clinical outcomes in patients treated with an investigational interspinous spacer (Superion) versus those treated with an FDA-approved spacer (X-STOP).
One hundred sixty-six patients with moderate lumbar spinal stenosis (LSS) unresponsive to conservative care were treated randomly with the Superion (n=80) or X-STOP (n=86) interspinous spacer.
Study subjects were followed through 6 months posttreatment.
Zurich Claudication Questionnaire (ZCQ) symptom severity scores improved 30% with Superion and 25% with X-STOP (both P<0.001).
Similar changes were noted in ZCQ physical function with improvements of 32% with Superion and 27% with X-STOP (both P<0.001).
Mean ZCQ patient satisfaction score ranged from 1.7 to 2.0 in both groups at all follow-up visits.
The proportion of subjects that achieved at least two of three ZCQ clinical success criteria at 6 months was 75% with Superion and 67% with X-STOP.
Axial pain decreased from 55±27 mm at pretreatment to 22±26 mm at 6 months in the Superion group (P<0.001) and from 54±29 mm to 32±31 mm with X-STOP (P<0.001).
Extremity pain decreased from 61±26 mm at pretreatment to 18±27 mm at 6 months in the Superion group (P<0.001) and from 64±26 mm to 22±30 mm with X-STOP (P<0.001).
Back function improved from 38±13% to 21±19% with Superion (P<0.001) and from 40±13% to 25±16% with X-STOP (P<0.001).
Preliminary results suggest that the Superion interspinous spacer and the X-STOP each effectively alleviate pain and improve back function in patients with moderate LSS who are unresponsive to conservative care.
