Abstract

Anatomical variations related to the sciatic nerve and its surrounding structures are well-documented, relevant for certain medical procedures, and identified as contributors to pathological conditions. Variations of the sciatic nerve are often classified by its relative position to the piriformis muscle. However, there are inconsistencies in the description and depiction of these variations, along with instances of atypical variations that do not fall within any specific classification. This case report describes an anatomic abnormality found during a routine cadaver dissection involving the bilateral presence of a double piriformis, absence of sciatic nerve formation (tibial and common fibular nerves never within a shared sheath) and an atypical course of the inferior gluteal vessels perforating the right tibial nerve.

臀深部的非典型变异：以双梨状肌、坐骨神经不成型和臀部血管走向异常为特征的病例报告

与坐骨神经及其周围结构有关的解剖变异已被充分记录，与某些医疗程序相关，并被确定为导致病理状况的因素。坐骨神经的变异通常根据其与梨状肌的相对位置进行分类。然而，对这些变异的描述和描绘并不一致，还有一些不属于任何特定分类的非典型变异。本病例报告描述了在一次常规尸体解剖中发现的解剖异常，涉及双侧双梨状肌、坐骨神经缺失（胫神经和腓总神经从未共用一个鞘）以及右侧胫神经下臀血管穿孔的非典型走向。

期刊介绍： Translational Research in Anatomy is an international peer-reviewed and open access journal that publishes high-quality original papers. Focusing on translational research, the journal aims to disseminate the knowledge that is gained in the basic science of anatomy and to apply it to the diagnosis and treatment of human pathology in order to improve individual patient well-being. Topics published in Translational Research in Anatomy include anatomy in all of its aspects, especially those that have application to other scientific disciplines including the health sciences: • gross anatomy • neuroanatomy • histology • immunohistochemistry • comparative anatomy • embryology • molecular biology • microscopic anatomy • forensics • imaging/radiology • medical education Priority will be given to studies that clearly articulate their relevance to the broader aspects of anatomy and how they can impact patient care.Strengthening the ties between morphological research and medicine will foster collaboration between anatomists and physicians. Therefore, Translational Research in Anatomy will serve as a platform for communication and understanding between the disciplines of anatomy and medicine and will aid in the dissemination of anatomical research. The journal accepts the following article types: 1. Review articles 2. Original research papers 3. New state-of-the-art methods of research in the field of anatomy including imaging, dissection methods, medical devices and quantitation 4. Education papers (teaching technologies/methods in medical education in anatomy) 5. Commentaries 6. Letters to the Editor 7. Selected conference papers 8. Case Reports
