Abstract
Background
The anatomical variations at the suprascapular region have great impact on the suprascapular nerve and its entrapment syndrome.
Aim
This study aimed to describe the morphological types and morphometric parameters of the superior transverse scapular ligament (STSL) and its relation to suprascapular neurovascular triad.
Material & methods
The suprascapular region was dissected in 60 (40 male & 20 female) cadaveric shoulders. The morphological variants, length, widths, thickness of STSL, and its relation to suprascapular triad were evaluated.
Results
Five morphological types of STSL were identified. The common variant was the fan-shaped followed by the band-shaped and the triangular-shaped, while the ossified and bifid forms revealed lower incidence rates with no side or sex significant difference. Morphometrically, the length of STSL measured 16.4 ± 2.4 mm, medial width was 13.3 ± 3 mm and its lateral width measured 5.4 ± 1.3 mm with no side significant difference (p > 0.05). Moreover, its length measured 16.6 ± 2.6 mm in male and 15.8 ± 1.9 mm in female, its medial width was 13.7 ± 2.2 mm in male and 12.2 ± 2 in female, and its lateral width measured 5.6 ± 1.3 in male and 5.1 ± 1.1 mm in female specimens. The relation between the suprascapular triad and STSL showed three main variants: where the blood vessels pass above the STSL (56.7 %), followed by the passage of the artery above and the vein below STSL (23.3 %), and the blood vessels below STSL (11.7 %).
Conclusion
Knowledge the morphological variants and morphometric measurements of STSL and its relation to the suprascapular triad are important during surgical and arthroscopic procedures of the shoulder 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
