Abstract

Introduction

The extensor digitorum communis (EDC) is essential in finger extension. Its tendons vary in distribution among and between different populations. These variations in anatomy can be very important for the diagnosis and management of hand injuries among hand surgeons, anatomists, and clinicians. This study is done to assess the variation of EDC tendons among the Burmese population and assess their distribution patterns on both hands.

Methods

This is a cross-sectional anatomical study involving 32 cadavers (16 formalin-preserved and 16 fresh-frozen-acquired) from various medical institutions in Myanmar. A total of 64 dissected hands were observed for the number, pattern, and distribution of EDC tendons to the index (IF), middle (MF), ring (RF), and little fingers (LF). The Chi-square test was used to determine the statistical significance of tendon variations among the hands.

Results

All IF had a single EDC tendon (100 %). The MF had single (50 %), double (37.5 %), and triple (10.9 %) tendons. The ring finger displayed single (9.4 %), double (50 %), triple (35.9 %), and quadruple (4.7 %) tendons. The LF showed an absent EDC tendon (60.9 %), a single tendon (34.4 %), and a double tendon (4.7 %). Asymmetrical tendon distribution was observed in 62 % of cadavers. Statistical analysis confirmed significant variations in EDC tendon distribution (p < 0.001).

Conclusion

This study represents valuable data on anatomical variations in EDC tendons among a Burmese population and emphasises an individualised approach to surgery when dealing with tendon repair or hand reconstruction. The high incidence of asymmetrical patterns may alter functional and biomechanical results. Further investigation with advanced imaging techniques and samples of larger sizes is recommended regarding clinical implications.

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
