Abstract
Objective: To evaluate the spectrum of MRI findings in various non-traumatic hip pathologies and assess the utility of MRI in their diagnosis and characterization. Methods: This retrospective study analyzed MRI findings in 56 patients with non-traumatic hip disorders, including osteonecrosis of femoral head (ONFH) (n=12), inflammatory arthritis (n=14), infective arthritis (n=18), degenerative arthritis (n=4), transient osteoporosis of hip (n=3), metastasis to hip joint (n=2), trochanteric syndrome (n=2), and gluteus medius tendinosis with bursitis (n=1). MRI examinations were performed using a 3.0 Tesla scanner with a standardized protocol. Images were evaluated by a single experienced musculoskeletal radiologist for specific findings associated with each pathology. Results: Key findings included bone marrow edema (91.7%) and double-line sign (83.3%) in ONFH; synovial thickening (100%) and enhancement (92.9%) in inflammatory arthritis; joint effusion (100%) and synovial enhancement (94.4%) in infective arthritis; and joint space narrowing and osteophytes (both 100%) in degenerative arthritis. Transient osteoporosis of hip cases showed bone marrow edema. Metastasis cases demonstrated focal bone marrow abnormalities and cortical destruction. Trochanteric syndrome cases exhibited bursal fluid and soft tissue edema. Conclusion: This study highlights the diverse spectrum of MRI findings in various hip pathologies, demonstrating the utility of MRI in differentiating and characterizing these conditions. The findings contribute to the growing evidence supporting MRI as a valuable tool in the evaluation of complex hip disorders.
