Bilateral C5 nerve branch supplies the levator scapulae and serratus anterior muscles: A cadaveric case report
Background
Variation of the different components of the brachial plexus is fairly common and well documented. Some of these variations may have clinical consequences in terms of clinical manifestations or altering the surgical intervention plan while others may be benign with no functional or clinical consequences. Therefore, thorough reporting and knowledge of different anatomical variations is of utmost clinical importance.
Method
During routine human anatomical dissection of the axilla and posterior triangle of the neck, an unusual C5 nerve branch caught our attention. After careful cleaning and thorough dissection of the brachial plexus, we realized the full details of this anomalous variant of C5 nerve branch.
Results
Here, we report bilateral anatomical variance of the C5 nerve root which supplied the levator scapulae muscle (LSM) and superior slip of the serratus anterior (SSSA). This innervation was completely independent of the dorsal scapular (DSN) and long thoracic nerves (LTN), both of which existed bilaterally. However, on the right side, the LTN did not receive any contribution from C5, whereas on the left side the LTN did receive a contribution from C5.
Conclusion
We believe this is one of the rare reports of a C5 nerve root having combined LSM and serratus anterior (SA) innervations bilaterally. As such, this finding may prove useful in clinical applications such as LTN injury, thoracic outlet syndrome, winged scapula, and surgical cases pertaining to the head and neck.
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
