Abstract

Background: The suprascapular notch, located at the superior border of the scapula, is a crucial anatomical structure facilitating the passage of the suprascapular nerve and vessels. Variations in its morphology have garnered attention due to potential clinical implications, particularly in conditions like suprascapular nerve entrapment. Despite ongoing exploration, a comprehensive understanding of these variations is still evolving. Objectives: To comprehensively investigate suprascapular notch variations and their clinical implications through literature synthesis, imaging analysis, association assessment, and comparison with recent literature. Materials and Methods: This study was conducted in Saidu Group of Teaching Hospitals, Swat from 1.1.2023 to 1.12.2023 using medical record to identify relevant studies exploring suprascapular notch variations. Inclusion criteria comprised studies providing detailed descriptions of notch morphology, while exclusion criteria excluded studies lacking specific descriptions of notch variations. Imaging data from 125 patients undergoing X-ray, MRI, or CT scans were analyzed. Notch morphology was independently reviewed by radiologists and anatomists. Variations were classified based on established criteria, and associations with demographic and clinical factors were assessed using chi-square tests. Results: The study identified 25 relevant studies, providing insights into notch variations based on anatomical dissections, imaging studies, and clinical observations. Imaging analysis of 125 cases revealed a high prevalence of V shaped notches (44.8%), followed by U-shaped notches (24.0%) and irregular notches (20.0%). Bony bridges were observed in 11.2% of cases. No significant associations were found between notch morphology and age, gender, or clinical symptoms, except for a correlation between bony bridges and a history of shoulder trauma. Conclusion: This study contributes to the understanding of suprascapular notch variations by synthesizing existing literature and presenting original observations. The high prevalence of V-shaped notches and variable rates of other morphological variations underscore the complexity of notch morphology. Associations between notch variations and clinical factors provide insights into potential implications for patient care. Continued research in this area is essential to enhance diagnostic accuracy, treatment outcomes, and anatomical education.
