Role of MRI in Early Detection of Non-Neoplastic Articular Causes of Hip Joint Disability in Adults

Abstract

Background Painful hip is a common problem in the absence of a known acute trauma, it can be a diagnostic problem as it can be attributed to many causes. The most common causes are avascular necrosis, transient osteoporosis, osteoarthritis, FAI or inflammatory causes. Aim of the Work The aim of this study is to clarify the role of MRI in diagnosis of the etiology of hip pain in adults that causes hip joint disability and to compare between the accuracy of both conventional radiography and MRI in various abnormalities and conventional MRI and MR arthrography in FAI and labrum tear. Patients and Methods This study was conducted on 96 symptomatic patients (14 males and 16 females with age ranged from 18 to 68 years) diagnosed clinically with hip joint disability due to certain hip pathology at Orthopedic and Physiotherapy Departments and referred to Radiodiagnosis Department of Ain shams University Hospitals. Results After statistical analysis of the results depending on the final outcome of the cases, it was found that MRI is more sensitive and specific than conventional radiography in detection of different hip joint pathologies with MRI sensitivity, specificity, and total accuracy ranging from 80 to 100% and conventional radiography sensitivity and specificity and total accuracy ranging from 50 to 90 %. Conclusion MRI has become an essential imaging modality in musculoskeletal system in general and in hip region specifically. It is a non-invasive technique with no radiation hazards, informative and essential in painful hip.
