Abstract

Hip disorders in a pediatric population are a diagnostic challenge. The aim of the study is to assess the role of magnetic resonance imaging (MRI) in the evaluation of non-traumatic hip disorders in a series of Egyptian patients and to review the literature on the most common hip conditions. Seventy two consecutive patients [40 males (55.6%) and 32 females (44.4)] with acute onset of hip complaints unrelated to trauma or falls were recruited. All patients underwent an initial full clinical assessment and blood tests as well as contrast enhanced MRI of both hips. The most common diagnosis in this group of Egyptian patients was transient synovitis in 29 (40.3%) cases, followed by seronegative enthesopathy and arthropathy syndrome in 8 (11.1%), septic arthritis in 10 (13.9%), tuberculous arthritis in 4 (5.6%), sickle-cell disease in 7 (9.7%), complicated with septic arthritis in 3 (4.2%), transient bone marrow edema (BME) in 3 (4.2%), osteomyelitis in 2 (2.8%), osteosarcoma in 2 (2.8%), sciatic nerve injury in 1 (1.4%), leukemia with BME in 1 (1.4%), coxa vara of both hips and L5/S1 facet joint ankylosis in 1 (1.4%), and a benign bone cyst in 1 (1.4%). MRI studies showed hip effusion in a total of 51 patients (70.8%), joint space narrowing in 9 (12.5%), and BME in 15(20.8%). MRI is a sensitive tool for assessing hip disorders in a pediatric population and can play an important role in both diagnosis and management of different hip disorders, irrespective of the underlying pathology.
