Abstract
Background
Among the various aspects of scapular anatomy, the suprascapular notch has gained attention as its anatomical variation is a predisposing factor for compression of the suprascapular nerve in this region, potentially impacting orthopedic surgery. This study aims to investigate the morphology of suprascapular notch (SSN) and its variation with age and sexual dimorphism. It also seeks to classify and correlate the superior angle of the scapula with the SSN in the Indian population.
Methods
A retrospective analysis of 360 computed tomography scans of scapulae of 180 adults was conducted. The morphology of SSN was classified according to Rengachary's classification (types I-VI), and the maximum depth (MD) and maximum width (MW) of SSN were measured. The superior angle of the scapula was classified based on morphological characteristics.
Results
Type I SSN was the most prevalent, suggesting lower susceptibility to suprascapular nerve entrapment. Males had significantly greater MD than females. Identical types of SSN and superior angles on both sides of the scapula were statistically significant, though variations on each side were also observed. There was no significant difference in age. The superior angle of the scapula was classified into four types: Hilly, mountain peak, crescent, and chimney, with the hilly type being the most common. No correlation was found between SSN and the superior angle.
Conclusion
These findings may provide a comprehensive understanding necessary for accurate diagnoses of related abnormalities and for performing safe and effective endoscopic and open surgical procedures in the suprascapular region.
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
