Abstract
Introduction: The aim of this study was the evaluation of symptom improvements in patients with moderate lumbar spinal stenosis, who consecutively underwent placement of interspinous distraction deviceIMPALA®.Methods: This study included a total of 11 adult patients with moderate lumbar spinal stenosis. Clinical evaluations were performed preoperatively and 3-months after surgery using the Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI).Results: The mean preoperative VAS was 7.09 and fell to 2.27 a 3-months after surgery. The mean preoperative ODI was 59.45 fell to 20.72 a 3-months after surgery.Conclusions: Using the IMPALA® device in patients with moderate lumbar spinal stenosis is a minimal invasive, effective and safe procedure. Clinical symptoms were improved 3 months after surgery.

Patients The study included a total of 11 adult patients with moderate lumbar spinal stenosis, who consecutively underwent placement of interspinous distraction device at 1 or 2 levels between October 2011 and February 2013 at Department of neurosurgery, Clinical Center University of Sarajevo
Lumbar spinal stenosis in all patients was confirmed by MRI scans
Summary
The aim of this study was the evaluation of symptom improvements in patients with moderate lumbar spinal stenosis, who consecutively underwent placement of interspinous distraction device IMPALA®. Lumbar spinal stenosis (LSS) is a condition involving the narrowing of either the spinal canal or neural foramina. The most common symptom associated with LSS is neurogenic intermittent claudication. (NIC) and typically concerns patients at the age of 50 or above. The symptom is typically relieved by various manoeuvres that flex the lumbar spine, such as bending forward or sitting, which increases the spinal canal significantly. The best treatment of NIC due to lumbal stenosis remains controversial. Decompressive surgery with or without fusion is the current ‘gold standard’treatment for moderate to severe symptomatic LSS [1,2,3,4].
