Epidemiology and Morphological Hallmark in Symptomatic Spondylotic Beninese Patients

Abstract

Spondylolisthesis is a well-known neurosurgical condition, in relation with various factors. The main objective was to report the morphological and radiological hallmark of patients presenting with symptomatic spondylolisthesis. This is a prospective, longitudinal, descriptive and analytical study: 1st April to 30th September 2014. Twenty nine patients were followed up, with female ascendance. The average age is 50 to 69 years. The most frequent level was L4-L5 and in most cases, only one level was involved. Lesions of Grade I were commonest (79.0%). The average values of the SS (sacral slope) and PI (pelvic incidence) was respectively 36.4 ± 6.9° (17.3° to 49.6°) with a median of 37.8° and 64.9 ± 9.2° (42.98° to 87.47°) with a median of 64.6°. LL (lumbar lordosis), had a mean value of 43.8 ± 10.8° (26.2° to 67.0°) with a median of 43.1°. DH (disc height) was 5 to 10 mm in most cases. A report was made with the morphology of the basin of the African woman. Our results are consistent for the most part with the literature data. This present study illustrates a female to male ration of 3. According to BMI (body mass index) assessment, 69% of patients presented with overweight. The main radiologic parameters are compromised with increasing sacral slop and PI and reduction of DH and LL. Findings are characteristic in female population.
