From: Overuse-related instability of the elbow: the role of CT-arthrography
CT-arthrography coronal (a, c, e, g) and axial (b, d, f, h) images belonging to four patients, three of which display different aspects of symptomatic minor instability of the lateral elbow (SMILE), involving the RCL (white arrows). Intact radial band (RCL) of the lateral collateral ligament (LCL) complex (a, b). Widening of the lateral aspect of the articular recess associated to a curve-shaped, loose RCL with no evidence of fiber tearing, suggestive of patholaxity (c, d). Thickened and irregular RCL showing partial-thickness tear (e, f) and full-thickness tear (g, h); iodinated contrast progressively leaks through the ligament, as fibers are gradually disrupted and damage progresses from a partial to a full-thickness tear
