| Abstract | ||
| Background: Excessive use disorders and inflammatory conditions often affect the elbow. Different types of imaging can be utilized to evaluate the elbow, such as conventional tomography (CT), Magnetic resonance imaging (MRI), ultrasonography (US), etc. Imaging had an important role as it helps in evaluating elbow tendons and ligaments and bony lesions. Methods: The current research was conducted as a cross-sectional analysis and involved thirty participants that were elbow pain. All patients underwent elbow US and MRI studied Results: On evaluating diagnostic accuracy of US in comparison to MRI as the gold standard test in patients with ulnar neuropathy; US showing 90% sensitivity and specificity of 84.2%. On evaluating diagnostic accuracy of US in comparison to MRI as the gold standard test in patients with epicondylitis tendinopathy; US showing 93.3% sensitivity and specificity of 86.7%. On evaluating diagnostic accuracy of US in comparison to MRI as the gold standard test in patients with distal biceps brachii injury; US showing 66.7% sensitivity and specificity of 76.2%. Conclusion: Ulnar nerve entrapment in the elbow region is a frequent entrapment mono-neuropathy, Our findings indicate that the use of ultrasound (US) is an accurate and precise tool for identifying ulnar neuropathy at the elbow. Additionally, the US is becoming more and more preferred for the diagnosis of medial and lateral epicondylitis with high sensitivity & specificity. However. In terms of diagnosing and classifying distal biceps brachii injuries, ultrasound demonstrated lower sensitivity than MRI, which was attributed to deep anatomic structures and problematic patient positioning. | ||
