    Co-Authors: Artur Bachta, Krzysztof Rowicki, Bartłomiej Kisiel, Magdalena Żabicka, Sylwia Elert-kopeć, Janusz Płomiński, Witold Tłustochowicz, Artur Maliborski
    Abstract:

    Objectives To investigate the diagnostic performance and reliability of ultrasonography (US) in detecting and grading Common Extensor Tendon (CET) tear in patients with chronic lateral epicondylitis (LE), using magnetic resonance imaging (MRI) as the reference standard. Materials and methods The study comprised fifty-eight chronic LE patients. Each patient underwent US and MRI. CET status was classified as: high-grade tear (≥50% thickness), low-grade tear (

Materials and methods The study comprised fifty-eight chronic LE patients. Each patient underwent US and MRI. CET status was classified as: high-grade tear (≥50% thickness), low-grade tear (<50% thickness), suspected tear (possible but not evident tear), no tear. Additionally, the following dichotomous scale was used: confirmed or unconfirmed CET tear. Relative US parameters (versus MRI) for detecting CET tear included: sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy. The agreement between US and MRI findings was measured using the weighted Cohen kappa coefficient (κ). Results US showed moderate agreement with MRI in detecting and grading CET tear (κ = 0.49). Sensitivity, specificity, and accuracy in CET tear detecting by US were 64.52%, 85.19%, and 72.73%, respectively. PPV and NPV of US were 83.33% and 67.65%, respectively. No patient with unconfirmed CET tear on US had high-grade CET tear on MRI. Conclusion Ultrasonography is a valuable imaging modality that can be used as a screening tool to exclude high-grade CET tear in chronic LE patients. Once a tear is evident on US, MRI should be considered to assess precisely the extent of Tendon injury.

  • MR Imaging of Patients with Lateral Epicondylitis of the Elbow: Is the Common Extensor Tendon an Isolated Lesion?
    PLoS ONE, 2013
    Co-Authors: Zhengfeng Zhu, Ren-fa Wang
    Abstract:

    Objective To investigate whether an injury of the Common Extensor Tendon (CET) is associated with other abnormalities in the elbow joint and find the potential relationships between these imaging features by using a high-resolution magnetic resonance imaging (MRI). Methods Twenty-three patients were examined with 3.0 T MR. Two reviewers were recruited for MR images evaluation. Image features were recorded in terms of (1) the injury degree of CET; (2) associated injuries in the elbow joint. Spearman’s rank correlation analysis was performed to analyze the relationships between the injury degree of CET and associated abnormalities of the elbow joint, correlations were considered significant at p

Spearman’s rank correlation analysis was performed to analyze the relationships between the injury degree of CET and associated abnormalities of the elbow joint, correlations were considered significant at p<0.05. Results Total 24 elbows in 23 patients were included. Various degrees of injuries were found in total 24 CETs (10 mild, 7 moderate and 7 severe). Associated abnormalities were detected in accompaniments of the elbow joints including ligaments, Tendons, saccussynovialis and muscles. A significantly positive correlation (r = 0.877,p<0.01) was found in injuries of CET and lateral ulnar collateral ligament (LUCL). Conclusion Injury of the CET is not an isolated lesion for lateral picondylitis, which is mostly accompanied with other abnormalities, of which the LUCL injury is the most Commonly seen in lateral epicondylitis, and there is a positive correlation between the injury degree in CET and LUCL.

  • Interobserver variability and stiffness measurements of normal Common Extensor Tendon in healthy volunteers using shear wave elastography
    Skeletal Radiology, 2019
    Co-Authors: Halit Nahit Şendur, Emetullah Cindil, Mahinur Cerit, N. B. Demir, Aylin Billur Şendur, Suna Özhan Oktar
    Abstract:

    Objectives The purposes of our study are to determine the quantitative elasticity values of normal Common Extensor Tendon (CET) and to assess the interobserver variability of stiffness measurements using shear wave elastography (SWE). Materials and methods A total of 60 CETs of 30 (15 female, 15 male, mean age 30.2 years) healthy volunteers without any symptoms of lateral epicondylitis were examined by two radiologists. Age, sex, height, weight, body mass index (BMI), and dominant hand of all participants were noted. The first observer performed B-mode and SWE imaging, and the second observer performed only SWE imaging. Tendon thickness and stiffness values in kPa were measured. Results The mean thickness of CETs was 3.57 ± 0.36 mm. The mean stiffness values of CETs for two observers were 45.28 ± 9.82 kPa and 45.80 ± 9.72 kPa respectively. Tendon thickness had a weak correlation with weight ( r  = 0.281, p  = 0.03), and moderate correlation with stiffness values ( r  = 0.429, p
