No Joint Injection or Neck Pain With New MRI Wrist Traction Device

Background: Wrist MRI is highly accurate in identifying tears of the triangular fibrocartilage complex, but is less accurate in identifying articular cartilage injury. Traction of the wrist during MRI can aid in the detection of these cartilage injuries, but it is typically done with the patient's arm in the "superman" position and requires joint injection. The authors developed a new wrist traction device that does not require joint injection. Objective: To evaluate the distraction effect, intrinsic structure visibility, and wearability of a novel direct wrist traction device for wrist MRI. Design: Prospective cohort study. Participants: Healthy male and female subjects with no history of wrist injury or pain, enrolled from January 2024 to July 2025. Methods: The wrist traction device developed by the authors consisted of 3 parts: a T-shaped lever extension arm with an adjuster, disposable Chinese finger traps, and a Velcro sleeve. The MRI was acquired with a 3.0 T MR scanner using more...
