Abstract

The present study aimed to evaluate the early effects of interspinous spacers on lumbar degenerative disease. The clinical outcomes of 23 patients with lumbar degenerative disease, treated using interspinous spacer implantation alone or combined with posterior lumbar fusion, were retrospectively studied and assessed with a visual analogue scale (VAS) and the Oswestry Disability Index (ODI). Pre‑operative and post‑operative interspinous distance, disc space height, foraminal width and height and segmental lordosis were determined. The early effects and complications associated with the interspinous spacers were recorded. The surgical procedures performed with the in‑space treatment were easy and minimally invasive. The VAS scores and ODI were improved post‑operatively compared with pre‑operatively. Significant changes in the interspinous distance, disc space height, foraminal width and height and segmental lordosis were noted. In‑space treatment for degenerative lumbar disease is easy and safe, with good early effects. The in‑space system provides an alternative treatment for lumbar degenerative disease.
