| Sacrum is formed by the fusion of five sacral vertebrae and forms the lower part of vertebral column. The opening present at the lower end of sacral canal is known as sacral hiatus. Anatomical variations in morphology and morphometry of sacral hiatus are important clinically as well as surgically. 159 dry clean human Sacra were taken from Department of Anatomy, Sri Guru Ram Das Institute of Medical Sciences and Research Vallah (Amritsar). Various shapes of sacral hiatus were observed which included inverted U (42.95%), inverted V (27.51%), irregular (16.10%), dumbbell (11.40%) and bifid (2.01%). The apex of sacral hiatus was commonly found at the level of 4th sacral vertebra in 56.36%. The mean length of sacral hiatus was 22.69 mm. The mean anteroposterior... |

| Lumbosacral part of the spinal canal requires special attention because this is the site commonly involved in spina bifida, tethered cord syndrome and some other pathologies like fatty tumours in the spine, cysts and syrinxes. The diagnosis as well as the treatment of neural tube defects mandates an accurate knowledge of morphometry of lumbosacral vertebral canal. There are various reports on radiological morphometric measurements in human foetuses by various authors but these possess inherent variability due to imaging techniques, patient positioning, observer's measuring techniques and normal and pathological variations. To overcome all these limitations, direct measurements by vernier calliper were preferred. 30 Formalin preserved human foetuses, of all... |
