Abstract
Background
The use of extensor indicis proprius (EIP) muscle tendon for tendon grafting and transplantation in the management of hand injuries is common. Anatomical variations of the EIP tendons have been reported with variable prevalence and presentation in different populations worldwide. Knowledge of possible variation patterns is crucial in reconstructive surgery. The current study aims to describe the prevalence of anatomical variations of the EIP in the Burmese population.
Methods
A total of 50 cadavers (39 males, and 11 females) were dissected. Both upper limbs of each cadaver were observed. The presence of the EIP, the number of tendons, the origin and insertion of the muscle and its relation with the extensor digitorum communis (EDC) were recorded and variations reported.
Results
Of the 100 limbs studied in the 50 cadavers, only 1/100 limb was reported to have an absent EIP muscle and tendon. Of the remaining 99/100 limbs examined, one of them consists of a double tendon, that is, EIP and extensor indicis et medii communis (EIMC) were inserted separately onto the index finger and middle finger respectively on the dorsum of the left hand. Further to this, there is one case in which an extra muscle belly was observed in the EIP tendon, this muscle is commonly known as the extensor digitorum brevis manus muscle. All the EIP variations were observed in the male cadavers only.
Conclusion
Of the 50 cadavers studied, 3/100 limbs exhibited EIP variations in the current studied population. Population-specific studies on these variations may aid in a better understanding of the different anatomical patterns of the muscles in the dorsum of the hand. This may lead to improved diagnosis and surgical management of injuries to the dorsum of the hand and for the use of the EIP tendon in surgical grafts and transplantations.
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
