Fig. 1From: Evaluation of prestyloid recess morphology and ulnar-sided contrast leakage in CT arthrography of the wristOpening width (1), bulge width (2), and maximum distance between the recess tip and opening (3) were measured in the coronal plane, while the anterior–posterior diameter of the prestyloid recess (4) was evaluated in the axial plane (S = scaphoid, L = lunate, T = triquetrum, R = radius, U = ulna)Back to article page
