Radiopalmar complaints and scapholunate ligament (SLL) tears were evaluated.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>A total of 1053 wrists in 909 patients (mean age 43.4\u2009\u00b1\u200915.5 years, 602 females) were evaluated. All 308 RPG (Group 1; 308 patients, 29.2%) originated from the palmar capsule; 49 were unilocular, 95 oligolocular, and 164 multilocular; 745 wrists had no RPG (Group 2; 601 patients). One hundred and twenty-six RPG showed internal debris. The mean diameter was 8.5\u2009\u00b1\u20095.6\u2009mm (cranio-caudal) (1.0\u201332.9\u2009mm), 8.0\u2009\u00b1\u20094.1\u2009mm (medio-lateral) (1.0\u201331.9\u2009mm), and 3.7\u2009\u00b1\u20092.3\u2009mm (dorso-palmar) (0.4\u201316.0\u2009mm). 168 RPG showed direct contact with the radial vascular bundle, 24 with the flexor carpi radialis tendon, and 123 with the flexor pollicis longus tendon. In Group 1, significantly more patients showed partial (82\/308) [group 2: 45\/745, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001] or complete SLL tears (22\/308) [group 2: 20\/745, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001]. Of the patients with RPG, 15.3% presented with radiopalmar complaints. Only the dorso-palmar RPG diameter was positively correlated with radiopalmar complaints (for readers 1 and 2: r<jats:sub>s<\/jats:sub>\u2009=\u20090.66\/0.61, <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001, respectively), and the best dorso-palmar diameter cut-off value for the probability of having radiopalmar complaints was defined at 3\u2009mm (area under the curve (AUC) 0.74).
