Abstract

Background: In clinical scenarios such as pelvic fractures, damage to the obturator neurovascular bundle, obturator neuropraxia, and mesh placement in patients with incontinence, preserving the anatomical structures related to the obturator foramen (OF) is crucial. This study aims to investigate the anatomical variations of the OF as a guide for identifying failure criteria and improving success parameters in clinical practice.

Methods: The OFs of one hundred adult dry pelvic bones were examined. Measurements were evaluated using ImageJ software. The morphology of the OF and the presence of bony projections on the inner surface of the foramen were assessed.

Results: The anterior-posterior length was 5.24 ± 0.8 cm on the right and 5.17 ± 0.87 cm on the left. The superior-inferior length was 4.69 ± 1.83 cm on the right and 4.66 ± 1.69 cm on the left. The anterior-posterior vertical angle was 98.21 ± 9.95° on the right and 98.48 ± 13.9° on the left; the superior-inferior horizontal angle was 90.7 ± 10.95° on the right and 97.56 ± 9.42° on the left. The OF was categorized into six distinct types: quadrilateral (23%), ellipsoid (22%), and oval (17%). The ellipsoid-type OF showed a greater anterior-posterior length compared to the other types, while the triangular-type OF exhibited a greater symphysis pubis length. Notably, bony projections on the anterior edge of the inner surface of the OF were observed in 33% of cases. Additionally, bony projections on the posterior edge of the OF were described for the first time.

Conclusion: In cases where OF is narrow and variable, and where bony projections are present on its inner surface, performing an osteotomy may help protect the obturator neurovascular bundle.

闭孔解剖结构及其对骨盆的重要性interventıons。

背景：在骨盆骨折、闭孔神经血管束损伤、闭孔神经失用、失禁患者放置补片等临床情况下，保留与闭孔（OF）相关的解剖结构至关重要。本研究旨在探讨of的解剖学变异，作为临床实践中确定失败标准和提高成功参数的指南。方法：对100例成人干骨盆腔骨进行OFs检查。使用ImageJ软件评估测量结果。评估of的形态和骨突在孔内表面的存在。结果：右侧前后长度为5.24±0.8 cm，左侧为5.17±0.87 cm。上下长度分别为右侧4.69±1.83 cm和左侧4.66±1.69 cm。前后垂直角度右侧为98.21±9.95°，左侧为98.48±13.9°；上下水平角右侧为90.7±10.95°，左侧为97.56±9.42°。OF被分为六种不同的类型：四边形（23%）、椭球体（22%）和椭圆形（17%）。与其他类型相比，椭球型OF表现出更大的前后长度，而三角形型OF表现出更大的耻骨联合长度。值得注意的是，33%的病例在of的内表面的前缘观察到骨突起。此外，首次描述了of后边缘的骨突起。结论：对于狭窄多变的OF，以及其内表面存在骨突起的病例，行截骨术可能有助于保护闭孔神经血管束。

期刊介绍： Anatomy is a morphological science which cannot fail to interest the clinician. The practical application of anatomical research to clinical problems necessitates special adaptation and selectivity in choosing from numerous international works. Although there is a tendency to believe that meaningful advances in anatomy are unlikely, constant revision is necessary. Surgical and Radiologic Anatomy, the first international journal of Clinical anatomy has been created in this spirit. Its goal is to serve clinicians, regardless of speciality-physicians, surgeons, radiologists or other specialists-as an indispensable aid with which they can improve their knowledge of anatomy. Each issue includes: Original papers, review articles, articles on the anatomical bases of medical, surgical and radiological techniques, articles of normal radiologic anatomy, brief reviews of anatomical publications of clinical interest. Particular attention is given to high quality illustrations, which are indispensable for a better understanding of anatomical problems. Surgical and Radiologic Anatomy is a journal written by anatomists for clinicians with a special interest in anatomy.
