Ulnar collateral ligament: differentiation of displaced and nondisplaced tears with US and MR imaging.

Abstract

MR imaging is better than US, but both methods are useful in the evaluation of the torn UCL.

Thumb collateral ligament injuries in the athlete

“…While noninvasive and cost effective, US results have varied widely with an accuracy of 40-92% likely owing to dependence on the operator [23,24]. Results of MRI are more consistent, especially with dedicated extremity coils, and have been suggested to be more accurate when combined with arthrography [25,26]. Hergan et al [26] compared US and MRI showing 100% sensitivity and specificity of MRI compared to 88% sensitivity and 83% specificity of US (Fig.…”

Halteapparat zum standardisierten radiologischen Nachweis ulnarer Kapsel-Band-Läsionen am Daumengrundgelenk

“…Als Verfahren zur direkten Visualisierung des Bandapparates werden heute Sonographie und MRT angewandt [15,18]. Die invasive Arthrographie [3,26] hat sich nicht durchsetzen können.…”

“…Verletzungen des Daumengrundgelenks (MCP-Gelenk) treten insbesondere im Rahmen von Stürzen beim Skifahren, Ballspielen, Judo und Karate auf [1,3,13,15,17,28,29]. Meist ist das ulnare Kollateralband betroffen.…”

Magnetic resonance imaging in the evaluation of ligament injuries

“…One of the more common applications is for investigating the integrity of the medial (ulnar, UCL) and lateral (radial, RCL) collateral ligaments. Although there have been no large-scale studies to date, there appears to be a good correlation between findings on MRI and at surgery for the diagnosis of complete tears of the collateral ligaments of the elbow [29,30].…”

“…In this setting, MR arthrography has been promoted, especially for the investigation of partial-thickness undersurface tears in throwing athletes [30]. These individuals would likely be considered for more aggressive therapy than the nonathletic population.…”
