“…The most common site is the hip; other common sites are the knees, shoulders, and ankles. Ischemia of the femoral head accounts for nearly 10% of the 500,000 total hip replacements performed in the United States annually (59). Approximately 10%-20% of cases have no clear identifiable risk factor and are classified as idiopathic osteonecrosis (60).…”

During infancy and childhood, multiple developmental changes occur in the epiphysis. Initially the epiphysis is composed entirely of hyaline cartilage. As skeletal maturation progresses, one or several secondary ossification centers (SOCs) develop within the epiphyseal cartilage. The SOCs enlarge by endochondral ossification and undergo marrow transformation in a process analogous to that of the primary physis and metaphysis. Magnetic resonance (MR) imaging can be used to evaluate vascularity, marrow, and cartilage and plays a critical role in the assessment of epiphyseal disorders in children. In cases of shoulder and hip dysplasia, MR imaging demonstrates unossified structures and helps guide treatment. In cases of trauma, the intracartilaginous pathway of fractures, the degree of physeal involvement, and early bridge formation can be assessed. With the use of intravenous gadolinium-based contrast material, avascular necrosis and reperfusion can be characterized. This article reviews the normal structure of the epiphysis, its appearance at MR imaging, and age-related changes to the epiphysis. Common conditions that lead to epiphyseal damage in children are reviewed, with an emphasis on the role of MR imaging in diagnosis, prognosis, and treatment.

OBJECTIVE:To assess the role of MRI in cases of AVN of femoral head in sickle cell disease in comparison to x-ray. MATERIAL AND METHODS: 55 patients (110 hip joints) who were suffering from sickle cell disease (Confirmed by HB electrophoresis) & with complain' of pain in one or both hip joints, were examined by plain x-ray and 0.2 tesla MRI, using T1W (350ms/17ms), T2W (2200ms/110ms) and STIR (4000ms/80ms/90) sequences in axial, coronal and sagittal planes.

“…[44][45][46] In humans, signal intensity of red marrow infarcts is low on T1-and high on T2-weighted images without recognizable margin. [47][48][49][50] They are generally not detected on T1-weighted images due to the surrounding abnormal marrow. 48,50 After contrast injection, lack of enhancement can be observed early in the disease course.…”

This article addresses imaging features of epiphyseal osteonecrosis that have been highlighted by the use of magnetic resonance imaging, including better depiction of marrow infarcts, better knowledge of their natural history, and better understanding of the different patterns of epiphyseal osteonecrosis. Imaging features that enable differentiation between irreversible lesions, including epiphyseal osteonecrosis and rapidly progressive osteoarthritis, and spontaneously transient lesions, including transient osteoporosis and epiphyseal fractures, are emphasized.
