We compared ultrasound (US) with magnetic resonance (MR) findings of muscle tendon and ligaments (mt&l) of 17 men and 13 women, 16-66 years old, who suffered from acute ankle injury without bone fracture visible on conventional radiographs. Joint effusion (JE), and injury of the Tibials anterior muscle tendon (TAmt), Calcaneofibular ligament (CFl), Long flexor of the great toe muscle tendon (LFGTmt), Short peroneus muscle tendon (SPmt), Long peroneus muscle tendon (LPmt), and Anterior talofibular ligament (ATFl) were assessed by the US, at seven days, and MR, at seventeenth day. Grading of ligament and muscle tendon injury as stretching (Grade 1), partially ruptured (Grade 2), and complete rupture (Grade 3); no lesion was considered to be Grade 0. Joint effusion and ATFl were the most common lesions whereas the TAmt lesion was the least frequent: JE approximately ATFl > SPmt approximately LPmt > LFGTmt approximately CFl approximately TAmt. Both US and MR were equally sensitive in detecting the presence (or absence) of the mt&l ankle injury, whereas US was less specific than MR in detecting G3 injury.

    • "The results were considered to be negative (À) if there was no or a mild difference from the opposite side; however, the results were considered to be positive (+) if there was a pathologic instability consistent with an LLLA. A final validating direct sonography was conducted by an orthopaedic surgeon within 7 days of an injury using the methods described by Oae et al. [20] and Margetic et al. [17]. The operator performing this sonography was blinded for the results achieved with the three measurements (device of Hoffmann, arthrometer and clinical investigation) before. "

    ABSTRACT: Background: Ankle sprain injuries, often due to lateral ligamentous injury, are the most common sports traumatology conditions. Correct diagnoses require an understanding of the assessment tools with a high degree of diagnostic accuracy. Obviously, there are still no clear consensuses or standard methods to differentiate between a ligament tear and an ankle sprain. In addition to clinical assessments, stress sonography, arthrometer and other methods are often performed simultaneously. These methods are often costly, however, and their accuracy is controversial. The aim of this study was to investigate three different measurement tools that can be used after a lateral ligament lesion of the ankle with injury of the anterior talofibular ligament to determine their diagnostic accuracy. Methods: Thirty patients were recruited for this study. The mean patient age was 35±14 years. There were 15 patients with a ligamentous rupture and 15 patients with an ankle sprain. We quantified two devices and one clinical assessment by which we calculated the sensitivity and specifity: Stress sonography according to Hoffmann, an arthrometer to investigate the 100N talar drawer and maximum manual testing and the clinical assessment of the anterior drawer test. A high resolution sonography was used as the gold standard. Results: The ultrasound-assisted gadgetry according to Hoffmann, with a 3mm cut-off value, displayed a sensitivity of 0.27 and a specificity of 0.87. Using a 3.95mm cut-off value, the arthrometer displayed a sensitivity of 0.8 and a specificity of 0.4. The clinical investigation sensitivities and specificities were 0.93 and 0.67, respectively. Conclusions: Different assessment methods for ankle rupture diagnoses are suggested in the literature; however, these methods lack reliable data to set investigation standards. Clinical examination under adequate analgesia seems to remains the most reliable tool to investigate ligamentous ankle lesions. Further clinical studies with higher case numbers are necessary, however, to evaluate these findings and to measure the reliability.

    ABSTRACT: The aim of our study was to compare US, conventional MRI and MR arthrography findings in patients with anterior shoulder instability and with a clinical diagnosis of labral capsular ligamentous complex lesion. At the same time we evaluated the accuracy of MR arthrography in the diagnosis of this lesion. After approval of the local Ethics Committee, our department's Trauma Registry from July 2008 up to February 2012 was retrospectively reviewed to identify all eligible patients. Eligibility criteria included: 1)history of acute or chronic shoulder instability (more than three dislocations over a period of more than two months); 2) diagnosis of labroligamentous lesion. All patients were investigated with plain radiographs, Ultrasound Scans (US), Magnetic Resonance Imaging (MRI) and MR arthrography. Finally, all patients underwent an arthroscopy that confirmed the diagnosis. A total of 200 consecutive patients who met the inclusion criteria were included in this study. The mean age was 39 years (range 15 to 83); 147 were male and 133 involved the right shoulder. Chronic instability was documented in 133 patients, whereas acute instability was documented in 67 patients. We detected a statistically significant difference between US and MR arthrography in SLAP (Superior Labrum Anterior to Posterior) lesions (TypeII, III and IV), in Bankart lesions, in glenohumeral ligament lesions (superior, middle, anterior-inferior and anterior inferior glenohumeral ligament) in Hill-Sachs lesions, in diagnosing internal subacromial impingement and in normal findings. MR arthrography was superior to the US. A statistically significant difference was evident between MRI and MR arthrography findings in SLAP lesions (III and IV Type lesions), in glenohumeral ligament lesions (anterior inferior and posterior inferior glenohumeral ligament), in partial rotator cuff ruptures and in normal findings. MR arthrography diagnosed this lesion better than MRI without contrast. We also found a statistically significant difference between US and MRI findings in SLAP Type II lesions, in partial rotator cuff ruptures, in Hill-Sachs lesions and in diagnosing internal subacromial impingement. The US scan is a valuable diagnostic technique for rotator cuff complete or incomplete ruptures. For evaluating Hill-Sachs lesions or bony Bankart lesions, MRI is more accurate. In the case of labral capsular ligamentous complex lesions, MR arthrography is superior.
