“…We report here that subjects with the dimple of Venus had a significantly higher coronal canal diameter. This finding may be attributed to gender difference, as the prevalence of the dimple of Venus was higher in males in our study group considering that the diameter of the vertebral canal is known to be wider in males than in females [ 24 ].…”

Objectives: The present study aims to investigate whether the dimple of Venus affects the anatomy of spinopelvic junction. Subjects and Methods: Inclusion criteria were having a lumbar MRI examination in the last 1 year, being older than 18 years of age and being able to radiologically evaluate the whole vertebral colon and pelvic girdle. Exclusion criteria were having congenital diseases of the pelvic girdle/hip/vertebral column and history of fracture or previous surgery in the same anatomic regions. The patients’ demographic data and low back pain were noted. At radiological examination, the pelvic incidence angle was measured by lateral lumbar X-ray. The facet joint angle, tropism, facet joint degeneration, intervertebral disc degeneration, and intervertebral disc herniation at the level of L5-S1 were examined on lumbar MRIs. Results: We included 134 male and 236 female patients with a mean age of 47.86 ± 14.50 years and 48.49 ± 13.49 years, respectively. We found that the patients with the dimple of Venus had higher pelvic incidence angle (p < 0.001) and more sagittally oriented facet joint (right facet joint p = 0.017, left facet joint p = 0.001) compared to those without the dimple of Venus. There was no statistically significant relationship between low back pain and the presence of the dimple of Venus. Conclusions: The dimple of Venus affects the anatomy of the spinopelvic junction and is associated with an increased pelvic incidence angle and a more sagittally oriented facet joint angle.

Background There are no available local data regarding normal dimensions of the lumbar spine. MRI (Magnetic Resonance Imaging) is a useful imaging method for the evaluation of spinal anatomy. Objective To evaluate normal dimensions of spinal canal, vertebral bodies and intervertebral discs. Methods This study was carried out on a total of 106 asymptomatic healthy Kurdish volunteers using a 1.5 Tesla MRI system in the imaging centre of Sulaimani Teaching Hospital. Results The mean midsagittal diameters of the lumbar bony spinal canal were 16.59 mm, 15.53 mm, 14.88 mm, 15.04 mm and 15.95 mm respectively. The mean intervertebral disc heights were 8.37 mm, 9.64 mm, 10.71 mm, 11.44 mm and 10.56 mm respectively. Conclusion The midsagittal spinal canal diameter is larger than that reported by other researchers in the neighboring countries.
