Background: Osteoarthritis is a major joint disease between the elderly with the knee is the most common joint involved. Ultrasound is used for non-invasive assessment of knee joint status with evaluation of the meniscal position, joint space narrowing and presence of osteophytic lipping under load-bearing position for early detection of osteoarthritis. The aim of the study is to assess the role of high-resolution ultrasonography with dynamic assessment in evaluation of the medial compartment knee joint osteoarthritis.To investigate the correlation between the O.A grade determined by radiography and that by ultrasound evaluation and to investigate the diagnostic accuracy of O.A determined using US. Methods: This study was carried out at Radio diagnosis Department, Zagazig University Hospitals. The present study was carried on 35 patients of knee osteoarthritis. Diagnostic work up was done including plain radiography & MSUS. Results: Total of 38 of the 40 knees were correctly diagnosed by ultrasonography with sensitivity of 95 % and specificity of 80 %. The predictive value positive was 86.36 % and the predictive value negative was 92.3 % with 88.5% accuracy. Conclusions: Our results indicate that knee ultrasonography provides valuable information for the assessment of knee joint osteoarthritis. However, MSUS has an advantage of dynamic evaluation with qualitative and semi-quantitative assessment for early detection of knee O.A with good diagnostic accuracy.
Aim: The aim of this study is to evaluate role of magnetic resonance imaging and ultrasound in diagnosis of traumatic shoulder injuries. Patients and methods: Fifty patients who had one or more of post traumatic shoulder dislocation, pain or limitation of the affected shoulder joint movements were examined by gray scale ultrasound and conventional magnetic resonance imaging. Results: 18 cases were diagnosed as supraspinatus tears (11 partial tear and 7 complete tear). 8 cases were diagnosed as supraspinatus tendinosis. Four cases were diagnosed as acromioclavicular joint lesions 2 of them were diagnosed as acromioclavicular joint separation and 2 cases were diagnosed as acromioclavicular joint osteoarthritis and all of cases with acromioclavicular joint lesions were associated with impingement syndrome. 11 cases were diagnosed as Hill Sach`s fracture; 5 of them were associated with Bankart lesion. Two cases were diagnosed as biceps tendon instability. Four cases were diagnosed as biceps tenosynovitis. Conclusion: ultrasound should be increasingly used as the first-line imaging modality in the assessment of traumatic shoulder lesions. Further magnetic resonance imaging is needed in order to evaluate the joint in more detailed manner
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
