Design and Performance Analysis of a Dynamic Magnetic Resonance Imaging-Compatible Device for Triangular Fibrocartilage Complex Injury Diagnosis

Figure 11

Multiangle comparative analysis of the ulnar deviation motions of the wrist of the patient using MRI: (a) radial deviation motion of approximately 10°, (b) ulnar deviation motion of approximately 5°, and (c) ulnar deviation motion of approximately 20° (arrow points to the necrotic lunate, showing the black area in the image. Distance 1 indicates the change in relative position between the uncinate bone and triangular bone. Distance 2 is the change in the relative position between the triangular bone and ulna).
