Description
In this presentation, Eilis Fitzgerald discusses her research on the optimal placement of posterior portals in shoulder arthroscopy using CT images. She begins by acknowledging a typographical error in her presentation, emphasizing that she is presenting her master's research from University College Cork (UCC) rather than claiming ownership of the entire journal in which it was published. Fitzgerald outlines the significance of portal placement in shoulder arthroscopy, noting recent cadaveric studies highlighting anatomical variations around the glenohumeral joint that may affect surgical procedures.
Fitzgerald details her methodology, which involved analyzing CT thoracic scans to objectively map the trajectory of the posterior portal. Using OsiriX software, her study aimed to measure the distance between this theoretical trajectory and palpable anatomical landmarks, employing color-coded lines in diagrams to illustrate her findings. The research yielded essential data about the average distances from various landmarks, providing valuable insights into gender differences in anatomical placements, focusing on a large cohort of 266 shoulders.
While Fitzgerald confidently presents her findings, including no significant anatomical differences between right and left shoulders, she acknowledges the theoretical nature of her research and the challenge posed by significant outliers in her data. She concludes by stressing the importance of incorporating advanced imaging techniques in preoperative planning for arthroscopy to enhance surgical outcomes. The presentation concludes with an invitation for further discussion and questions from the audience.
