Abstract: The purpose of this article is to investigate the diagnosis of magnetic resonance technology (MRI) in ulnar impingement syndrome and its consistency with wrist arthroscopy, so as to provide reference for clinical diagnosis and treatment. All 92 patients with ulnar impingement syndrome (UIS) underwent MRI and wrist arthroscopy. Statistics on the diagnosis of UIS by wrist arthroscopy, the consistency of the degree of cartilage damage in the MRI diagnosis of UIS with wrist arthroscopy, and the degree of triangular fibrocartilage disc damage in the diagnosis of UIS The accuracy rate of MRI showed that there were 56 cases (60.87%) of ulnar positive variants in 92 UIS patients, 16 cases of ulnar negative variants (17.39%), and 20 cases of ulnar neutral variants (21.74%). The diagnostic accuracy rate of UIS was 96.74%. The Kappa value of MRI diagnosis of UIS cartilage damage and wrist arthroscopy was 0.918 (P<0.05). The overall accuracy of MRI diagnosis of the damage of the triangular fibrocartilage disc in UIS was 93.48%. It can be seen that MRI can accurately detect the damage and extent of the triangular fibrocartilage disc, the ulnar side of the lunar bone, the ulnar head, and the radial side of the triangle bone in the early stage. The diagnosis of cartilage damage is consistent with the wrist arthroscopy.
