摘要
Sciatica, mostly clinical-based diagnosis, is a potentially debilitating condition as a result of disco-radicular conflict between L4 and L5 or L5 and S1. This study aims at describing the epidemiological, clinical and etiological aspects of sciatica in Hubert Koutoukou Maga Teaching Hospital (CNHU-HKM) of Cotonou. It was a prospective, descriptive and analytical study conducted in CNHU-HKM Cotonou neurology department from 1st January to 30th June 2016. The study population comprised 115 low back pain patients seen in consultation. Data collection was carried out through a standard information sheet with socio-demographic, clinical, para-clinical, etiological and therapeutic data. Epi data 3.1 was used for data entry and Stata11 for processing. Frequency of sciatica was 18.6%, with 95% CI [11.5% - 25.7%]. The study population age ranged from 29 to 73 years, with 52 ± 16 as mean value, while sex ratio was estimated at 0.6. Bilateral sciatica representing 53% was present in L5 and S1 nerve roots in 44.4% of cases. It was exacerbated in prolonged standing (24.4%) and relieved in supine position (44.3%), with paresthesia (59.1%) and intermittent radicular claudication (40.9%). Spinal osteoarthritis was the most prevalent etiology (47%). Sciatica is becoming increasing prevalent and should be regarded as problem of health concern.
