Abstract

Introduction: Lumbar disc herniation is a common clinical condition in which pain severity and characteristics may differ according to the anatomical level involved. This study aimed to compare pain intensity and neuropathic pain features between patients with single-level L4-L5 and L5-S1 disc herniations. Methods: This cross-sectional observational study included 72 patients aged 18–80 years with MRI-confirmed single-level L4-L5 (n=46) or L5-S1 (n=26) herniations. Demographic and clinical data were recorded. Pain intensity was measured using the Visual Analog Scale (VAS) for current, most severe, and average pain. Neuropathic pain components were assessed with the PainDETECT questionnaire. Statistical analyses included independent-samples t-tests, Mann–Whitney U tests, and chi-square tests. Results: Mean age and sex distribution were similar between groups (p>0.05). VAS scores for current, most severe, and average pain did not significantly differ between L4-L5 and L5-S1 groups (p>0.05). However, a higher proportion of patients with L4-L5 herniation had PainDETECT scores ≥19, indicating probable neuropathic pain, compared with the L5-S1 group (63.0% vs. 26.9%, p=0.015). Radiating leg pain was also more common in the L4-L5 group (95.7% vs. 80.8%, p=0.042). Conclusions: While pain intensity was similar across groups, patients with L4-L5 herniations exhibited neuropathic pain features and radicular symptoms more frequently than those with L5-S1 herniations. These findings suggest that the anatomical level of disc herniation may influence pain quality, which could guide more tailored pain management strategies.

Özet

Giriş ve Amaç: Lomber disk hernisi, ağrı şiddeti ve karakteri açısından anatomik seviyeye bağlı farklılıklar gösterebilen yaygın bir klinik tablodur. Bu çalışmanın amacı, tek seviyeli L4-L5 ve L5-S1 disk hernisi olan hastalarda ağrı şiddetini ve nöropatik ağrı özelliklerini karşılaştırmaktır. Yöntem: Kesitsel gözlemsel olarak planlanan bu çalışmaya, MRG ile doğrulanmış tek seviyeli L4-L5 (n=46) veya L5-S1 (n=26) disk hernisi tanısı almış, 18–80 yaş arası toplam 72 hasta dâhil edildi. Demografik ve klinik veriler kaydedildi. Mevcut, en şiddetli ve ortalama ağrı şiddeti, Vizüel Analog Skala (VAS) kullanılarak değerlendirildi. Nöropatik ağrı bileşenleri ise PainDETECT anketi ile ölçüldü. İstatistiksel analizlerde bağımsız örneklem t-testi, Mann–Whitney U testi ve ki-kare testleri kullanıldı. Bulgular: Gruplar arasında ortalama yaş ve cinsiyet dağılımı benzerdi (p>0,05). Mevcut, en şiddetli ve ortalama ağrı için VAS skorları L4-L5 ve L5-S1 grupları arasında anlamlı fark göstermedi (p>0,05). Ancak, L4-L5 hernisi olan hastalarda PainDETECT skoru ≥19 olanların oranı L5-S1 grubuna göre daha yüksekti (%63,0’a karşı %26,9, p=0,015). Ayrıca bacaklara yayılan ağrı da L4-L5 grubunda daha sık görüldü (%95,7’ye karşı %80,8, p=0,042). Sonuç: Ağrı şiddeti gruplar arasında benzer bulunmasına rağmen, L4-L5 hernisi olan hastalarda nöropatik ağrı özellikleri ve radiküler semptomlar L5-S1 grubuna göre daha sık görülmektedir. Bu bulgular, disk hernisinin anatomik seviyesinin ağrı kalitesini etkileyebileceğini ve bu doğrultuda daha kişiye özel ağrı yönetim stratejileri geliştirilebileceğini düşündürmektedir.
