“…In MDCT studies, the mean value of APCWHSA was similar in men and women, and it was higher in men in studies conducted with USG. In studies conducted in MDCT, the mean value of male and female ICD was found to be lower than in studies performed with USG [39][40][41].…”

Objective: In recent studies, the relationship between sacrum morphology and orientation and spondylolisthesis has gained importance. The present study aimed to compare the morphometry of the sacrum between patients with L5-S1 spondylolisthesis and healthy subjects on multidetector computed tomography (MDCT) images. Methods: In this study, abdominopelvic MDCT images of 191 individuals (age range 20-92 years; 101 males and 90 females; 56 patients diagnosed with L5-S1 spondylolisthesis and 135 healthy individuals) were retrospectively evaluated. In this study, the sacrum parameters (Intercornual distance (ICD), sacral hiatus length (LHS), anteroposterior diameter of hiatus at the apex of sacral hiatus(APCWHSA), sacral height (SH), sacral table angle (STA), sacral table index (STI), S1 superior angle (S1A), sacral slope(SS)) evaluated morphometric and morphological in healthy individuals and patients with L5-S1 spondylolisthesis. Kolmogorov–Smirnov test was used to test the normality, which is one of the parametric test assumptions, of the data. Results: Age parameter was found statistically significant higher in the patient group (p<0.001). STA, S1A, SH, LHS and APCWHSA measurements were found to be significantly higher in the healthy group. (p<0.001, p<0.001, p=.008, p=.005, and p=.002, respectively). STI and ICD were found to be significantly higher in women in the healthy group (p=.031, p=.010), while SH parameter was found statistically significant higher in men in the healthy group (p=.007). SS was found statistically significant lower in the healthy group (p<0.001). S1A, L5-S1 spondylolisthesis was found statistically significant higher than Grade 1, Grade 2 according to the degree of slippage (p=.045). Conclusion: The results of this study showed that sacral morphology is important in the development or at least progression of spondylolisthesis.

“…The authors suggested that sacral cornua are inadequate as a bony landmark and thus cannot be utilised in CEB in 21.5-50% of the population. Furthermore, in a research study of 300 multidetector computed tomography (MDCT) images, bilateral plane cornua were found in 3%, unilateral plane cornua in 5%, bilateral short cornua in 7%, and unilateral short cornua in 15.3% [52]. In addition, sacral cornua were examined through three-dimensional computed tomography (3D CT) images in children and they were bilaterally absent in 3.5% and unilaterally absent in 4.2% [53].…”

Anatomy and clinical significance of sacral variations: a systematic review

The sacrum is a large trilateral bone located at the base of the vertebral column serving to transfer the body weight from the trunk to the pelvis and lower extremities. Over the years, an abundance of sacral anatomical divergences has been reported, including numerical and/or morphological variations of sacral entities. The majority of these anatomical alternations has been incidentally identified during radiological investigations, surgical procedures or discovered in anatomical, anthropological and forensic research studies. Throughout international literature, however, there is a scarcity of an integrative recording of all known anatomical variations of the sacrum in a single study. This constitutes the objective of the present paper: to provide an exhaustive systematic review of the relevant literature, as well as to thoroughly describe all the recognised deviations of the sacrum structure, while highlighting the aspects of their clinical significance.

“…In the remaining 15 cases with a needle distance over 6 cm, only six cases had a vertebral canal that was mildly curved, requiring that we obtain this needle distance by joining two straight lines at a slight angle (5° to 30°) off a straight path, along the lumen of the caudal epidural space. Riascos et al (2011) and Kilicaslan et al (2015) previously recorded similar average angulations within the vertebral canal on CT scans.…”

Imaging anatomy of the vertebral canal for trans‐sacral hiatus puncture of the lumbar cistern

2020

A standard lumbar puncture may be impossible for many anatomic or technical reasons. Previous accounts of caudal epidural anesthesia and other procedures via the sacral hiatus prompted us to test if image‐guided percutaneous trans‐sacral hiatus access to the lumbosacral subarachnoid cistern would be anatomically feasible. To study vertebral canal morphometry and curvature, we analyzed midsagittal computed tomography‐myelogram images of 40 normal subjects and digitally measured sacral curvatures between S1 to S5 and S2 to S4 using two methods whereby a lower angle signifies a straighter sacrum. We measured midsagittal vertebral canal area, hiatus width, dural sac termination levels, and distance from sacral hiatus to the dural sac tip (needle distance). Subjects were F:M = 25:15, with a mean age of 44.9 years. The two S1–S5 full sacral curvature mean angles were 57.3° and 60.4°. Almost all sacral hiatuses were at S4, and dural sac terminations were at S1–S2. The mean S2–S4 sacral curvature was 25.1°, and the mean needle distance was 57.7 mm. Using two‐way analysis of variance, there were significant sex differences for needle distances (p = .001), and full and limited sacral curvatures (p = .02, and p = .046, respectively). There were no significant linear regression correlations between age and sacral curvature, needle distance, canal area, or hiatus width. Therefore, despite a frequently prominent full sacral curvature, the combination of S1–S2 dural sac termination plus a relatively straight trajectory of the lower vertebral canal between S2 and S4 support the theoretical feasibility of percutaneous trans‐sacral hiatus and vertebral canal access to the lumbosacral cistern using a standard spinal needle.
