Viena iš tokių ligų yra stuburo kanalo stenozė, t. y. susiaurėjimas. Dažniausia stuburo kanalo stenozės priežastis yra su amžiumi progresuojantys stuburo degeneraciniai pokyčiai. Ne visada arklio uodegos ar nervų šaknelių spaudimas sukelia dirginimo simptomus, tačiau progresuojant patologiniams anatominiams ir fiziologiniams pokyčiams gali išryškėti klinika. Kartais rentgenologiniai duomenys neatspindi klinikos, todėl labai svarbu tiksliai įvertinti ligos simptomus, jų eigą bei rentgenologinius duomenis, kad būtų pasirinkta tinkama gydymo taktika.

Spinal stenosis is a narrowing or stricture of the spinal canal. Cauda equina and nerve root compression are noted in many asymptomatic individuals. The spinal degenerative process associated with ageing leads to pathoanatomical and pathophysiological changes with occasional clinical consequences. With progressive degenerative changes and compression, spinal stenosis may become symptomatic, although the severity of the symptoms is not necessarily associated with the magnitude of the compression seen on imaging studies. A thorough understanding of the etiology, pathologic features and a correlation between the symptoms and the precise location of the thecal sac and nerve root are very important in evaluating the imaging studies and planning appropriate treatment.

Objective: This study aimed to determine the association between redundant nerve root and clinical outcome after fusion for lumbar spinal stenosis by comparing outcomes in patients with or without redundant nerve root.Methods: A total of 163 patients who underwent spinal fusion surgery between January 1, 2014, and December 31, 2018, were enrolled. Patients were divided into two groups: with a redundant nerve root (R group) and without a redundant nerve root (N group). The clinical outcome of the two groups was compared using VAS and claudication distance.Results: A total of 46 patients had a redundant nerve root, while the remaining 117 did not. Symptom duration was significantly different between the two groups (R=41.0±25.0, N=24.1±12.2, p<0.001). Changes in the VAS score for lower extremity pain between the two groups at 1 year after surgery showed that patients without a redundant nerve root had significantly better outcomes than those with a redundant nerve root (R: 4.2±1.3 vs. N: 5.5±1.4; p<0.001). Conclusion: Redundant nerve root on MRI is associated with clinical outcome after fusion for lumbar spinal stenosis. Patients with a redundant nerve root had poor outcomes after fusion surgery for lumbar spinal stenosis than those without a redundant nerve root.
