Motivation: Traction imaging helps visualize the wrist articular cartilage, intrinsic ligaments, and triangular fibrocartilaginous complex (TFCC). The current traction method is cumbersome to use limiting more widespread usage.
Goal(s): To design a direct wrist traction device that is practical, comfortable, effective, and versatile.
Approach: A new traction device was designed. One patient underwent wrist imaging before and after traction with this device. The degree of joint distraction and articular cartilage, ligament and TFCC visibility was evaluated as was the degree of subject discomfort.
Results: The traction device was easy to apply, achieved good traction with minimal subject discomfort.
Impact: This practical traction device can potentially improve the quality of wrist MR imaging, negating the need for wrist arthrography and improving the detection of articular cartilage, intrinsic ligament and TFCC injury.
