Abstract

Introduction: This study was conducted on cadavers, determining the distance between major vascular structures and the dorsal portals for wrist arthroscopy, thereby assessing the risk of vascular injury during surgery. Materials and Methods: The study was conducted on 30 wrist joints from 15 cadavers (9 males, 6 females). The distance from the radial artery and ulnar artery to the arthroscopic portals (1-2, 3-4, 6R, 6U) was measured and analyzed. Comparisons were made between the two wrists and between the two genders using statistical tests. Results: The average distance from the radial artery to portal 1-2 is 12.65 ± 3.08 mm and to portal 3-4 is 23.37 ± 3.01 mm. The distance from the ulnar artery to the 6R and 6U portals was 17.24 ± 3.42 mm and 11.42 ± 3.14 mm, respectively. There is no statistically significant difference between the two wrists and between the two genders (p > 0.05). Portals 1-2 and 6U were identified as high-risk positions for vascular injury during surgery. Conclusion: The radial artery and ulnar artery are relatively close to the wrist arthroscopic portals, specifically portals 1-2 for the radial artery and 6U for the ulnar artery, indicating a risk of vascular injury during surgery. Accurately determining the positions of the portals as well as being cautious during surgical procedures can help minimize this risk, thereby enhancing the safety of wrist arthroscopy.
