ABSTRACT
Lumbar vertebral dimensions provide vital clinical information of immense diagnostic benefits to medical experts. The present study provides data for lumbar vertebral dimensions of a cohort of specimens of South African females and males. Measurements were obtained from lumbar vertebrae from the osteological collections in the Discipline of Clinical Anatomy, Nelson Mandela School of Medicine using a digital caliper. The antero-posterior body diameter (APD), interpedicular distance (IPD), midsagittal diameter (MSD) and pedicle length (PL) were measured while ratio of MSD to APD was calculated. Results showed gradual increase from L1 to L5 for mean APD and IPD, and a decrease for mean PL from L1 to L5. Mean MSD was observed to present a "U" curve pattern from L1 to L5, while MSD/APD ratio decreased from L2 downwards. We report that certain lumbar dimensions also showed significant correlation with age at distinct lumbar levels. The present data provides a baseline of lumbar vertebral morphology for the South African adult cohort and requires further investigations with larger cohort.
RESUMEN
Las dimensiones lumbares vertebrales proporcionan información vital en la clínica para alcanzar un diagnóstico correcto. El presente estudio proporciona datos de las dimensiones vertebrales lumbares en una cohorte de hombres y mujeres de Sudáfrica. Las mediciones de las vértebras lumbares se obtuvieron de colecciones osteológicas correspondientes a la Cátedra de Anatomía Clínica, de la Escuela de Medicina Nelson Mandela. Se utilizó un calibrador digital. Se midieron el diámetro antero-posterior del cuerpo vertebral (DPA), la distancia interpedicular (DIP), el diámetro sagital mediano (DSM) y la longitud del pedículo (LP); y se calculó la relación de DSM con DPA. Los resultados mostraron un aumento gradual de L1 a L5 para la mediana de DPA y DIP, y una disminución de la media de LP de L1 a L5. La media de DSM presentó un patrón de curva en "U" de L1 a L5, mientras que el índice DSM / DPA disminuyó de L2 hacia inferior. Ciertas dimensiones lumbares también mostraron una correlación significativa con la edad en los distintos niveles lumbares. El presente estudio proporciona datos acerca de la morfología vertebral lumbar para una cohorte de adultos de Sudáfrica, y consideramos que se requieren de más investigaciones con una cohorte más amplia.
