“…Although the SH shape has been typed differently in the literature, inverted 'U' and inverted 'V' are included in most studies. [22][23][24][25] In our study, SH was classified according to the study of Bagheri and Govsa's [10] classification. Consistent with studies in the literature, the most common inverted 'U' shape is seen in our study.…”

Objectives: The sacrum is a critical bone in various clinical procedures, including caudal epidural blocks, iliosacral screw placements, fetal growth assessment, and sacral nerve stimulation. This study aims to investigate the morphometry and variational morphology of the anatomical formations in the pelvis and dorsal surface of the sacrum. Methods: Morphometric and morphological characteristics of 30 sacral bones of unknown age and sex were examined. Measurements were made using a digital caliper. Results: The mean height of the sacrum was 106.67±10.16 mm, while their mean width was 103.60±6.78 mm. The morphometric analysis revealed that the mean length of the sacral hiatus was 18.51±7.44 mm, and the distance between the sacral cornua was 11.80±2.46 mm. The sacral hiatus was most commonly observed in an inverted ‘U’ shape, while the least common form was bifid. The sacral canal typically displayed a V-shaped morphology. It was determined that the apex of the sacral hiatus most frequently started at the S4 level (80%) compared to the sacral vertebra, and the base of the sacral hiatus mostly ended at the S5 level (93.4%). Conclusion: Morphometry of the sacrum is essential in guiding clinicians, especially in interventions such as anesthesia and orthopedics. Discrepancies in parameter studies conducted in some countries suggest the significance of ethnic factors. Therefore, it is essential for the number of studies to increase and for physicians to follow the parameters of their society regarding the effectiveness of the treatments.

“…Spina bifida and cystitis are co-occurring conditions with this illness, and neurological issues might be seen in this scenario. 21 The median sacral crest is created when the spinous processes unite at the midlineOn either side of the median sacral crest lies the sacral groove. The sacral groove is made up of sacral laminae.…”

Aims: The purpose of this study is to assess the architecture and clinical importance of the sacrum, which features the dorsal and pelvic nerves. Methods: 32 os sacrum of adult Anatolians of undetermined gender were measured for this investigation. Sacrum maximum length, os sacrum maximum width, sacrum I vertebral body antero-posterior width, sacrum I vertebral body transverse width, sacral index, Auricular surface short arm, auricular surface long arm and auricular surface oblique arm, the measurements of pelvic surface linea transverse length and, the measurements of dorsal surface linea transverse length and the sacrum height from the dorsal surface are evaluated. Results: Sacrum maximum length 103.30±10.03 mm, sacrum maximum width 108.40±6.10 mm, sacrum I vertebral body transverse width 47.00±5.00 mm, sacrum I vertebral body antero-posterior width 28.30±3.50 mm, sacral index 104.00±9.00, Auricular surface short arm 31.90±4.20 mm, Auricular surface long arm 39.40±4.80 mm, Auricular surface oblique arm 49.10±6.00 mm, the length measurements of dorsal surface distance respectively as mm; 36.72±0.37, 29.75±0.31, 26.53±0.33, 26.56±0.39, the length measurements of dorsal surface distance respectively as mm; 29.16±0.36, 27.16±0.33, 24.50±0.26, 24.38±0.24 and the sacrum height from the dorsal surface as 103.4±9.70 mm were calculated. Conclusion: Clinically stated, understanding the architecture of the sacrum and taking morphometric measures of it are crucial to avoiding difficulties and the surgical intervention that will be used to treat disorders associated to the sacrum.

“…Furthermore, extensive research was made on the number of other parameters like VDA, TDAAS, VDAAS, and TDA, No observable difference was found [14][15] . The morphology of AAS was quite different in different samples of the population when it was compared with the AAS of the western population.…”

Background: One of the large trilateral bones present at the base of the vertebral column is named as sacrum. The body weight transfers from trunk to pelvis and lower extremities. Different studies considering sacral morphological variations are conducted in the western world. The scope and knowledge of these studies in the eastern world is limited. Different sacral anatomies are reported by the scientists. Objective: The purpose of the study was to investigate and measure thoroughly the variable morphologies of sacrum. Study design: It is an investigational and cross-sectional study facilitated by statistical approach. Material and Methods: The study was conducted on 223 skeleton samples. These samples were preserved in the anatomy department of Mufti Mehmood Teaching Hospital Dera Ismail Khan and Bacha Khan Medical Complex Swabi during the period from October 2021 to June 2022. The human research ethical committee of the hospital approved the study. The vernier caliper was used to measure the correlation parameters of variability. The morphological features were calculated. The study also calculated the sacral variation incidence. The sacra with any kind of bony defects were excluded from the study. Results: The anatomical differences reported in the 223 samples were observed to be 59%. Out of the 223 patients the 81 were females and 142 were males. The five variations were reported in the sacral regions, while two samples have the rare sacral variations. The mean age of the included sample was observed to be 44 years. The age of the people whose sacral samples were included in the study was between 21-72 years. The percentage incidence of accessory auricular faces was observed to be 12.5%. The sacral skewness was observed in 24% cases. The 17% showed the transitional vertebra, while sacral spina bifida occulta was seen in 28% samples. Conclusion: This large scale anatomical study provides information about the apparent changes in the morphology of different sacral variables. This study provides comprehensive data about the different sacral variations. The detailed information about the human sacrum is provided. The apparent identification methods by western medical officers are also considered in this work which may help our medical staff to identify the sacral variations. Keywords: Sacrum variations, Sacrum morphology, Accessory auricular faces, Transitional vertebra and Sacral spina bifida occulta
