ABSTRACT

Background: The aim of this paper is to demonstrate the clinical and radiological results of non-fusion in patients with degenerative disc disease and lumbar by placing static interspinous spacer.
Methods: A retrospective study was made in the period between January 2010 and January 2013, 130 patients were treated by placing static interspinous spacer. Patients were divided into: Group 1 (treated for diagnosis of degenerative lumbar spinal stenosis), and group 2 (those diagnosed with lumbar disc herniation). It is improving pain by visual analog scale (VAS), functional improvement based on the Oswestry scale (ODI) and radiological outcome at 6,12 and 24 months was evaluated.
Results: 57 female patients and 73 male were included. The most affected segments were L4 - L5 and L5 - S1. In Group 1, there was improvement in pain (VAS) at 6 months to 2 points which was maintained through 12 months and 24 months was found in 4 points. Functional improvement (ODI) at 6 and 12 months remained 13 points and 24 points and 21 months in group 2: VAS 2.7, 3, 3.5 and ODI 15 respectively at 6 and 12 months; at 24 months was found in 20 points. There were no fatal complications in 1.5% in both groups. Regarding radiological changes increased the diameter foraminal which was held at the 6, 12 and 24 month follow-up.
Conclusions: The interspinous device is an effective alternative treatment for lumbar degenerative disc disease and because it was associated with significantly improved lumbar pain and return to work activity.
