Abstract

Introduction

The objective of this study is to report the variant formation and course of the median nerve, which was observed in the right arm of a male cadaver.

Methods

During the routine dissection procedure, it was observed that the median nerve was formed by the blending of three roots, which included one medial and two lateral roots.

Results

It is also further observed that the median nerve pierced the humeral head of pronator teres just above the medial epicondyle and it passed through the cubital fossa more medially and deeper, making it invisible.

Conclusion

Entrapment of median nerve by the pronator teres is among the causes of the proximal median nerve entrapment syndrome. In this context, this interesting and rare variation of pronator teres muscle being pierced by the median nerve will be of interest to the orthopedic specialists, neurosurgeons and hand surgeons. The present study also observed variant formation of the median nerve by triple roots, which is important both for the surgical and anesthesiologic perspective.

正中神经穿透肱骨头的旋前肌：关于非典型正中神经形成和走向的解剖病例报告

方法在常规解剖过程中，观察到正中神经由三条神经根混合形成，其中包括一条内侧神经根和两条外侧神经根。结果还进一步观察到，正中神经正好在内侧上髁上方刺穿了肱骨头的发音肌，并在更内侧和更深的位置穿过了肘窝，使其变得不可见。在这种情况下，骨科专家、神经外科医生和手外科医生会对这一有趣而罕见的正中神经穿刺发音肌变异感兴趣。本研究还观察到正中神经由三根形成的变异，这对手术和麻醉学角度都很重要。

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
