Transient synovitis Transient synovitis buy aldara 250mg low cost, also known as toxic synovitis or irritable hip, is an acute inflammatory arthritis of unknown aetiology. Usually presenting unilaterally, it is the commonest cause of an acute limp and pain in children under 10 years of age9. Ultrasound is the imaging modality of choice in the diagnosis of transient synovitis and the condition normally resolves over a period of 2 weeks if the joint is allowed to rest. Follow-up plain film radiography is necessary if the symptoms return or fail to resolve as recurrent transient synovitis is associated with Perthes’ disease (2–3% of cases)5,9,10. Developmental dysplasia of the hip Developmental dysplasia of the hip (DDH) is a generic term used to describe a spectrum of anatomical hip abnormalities5. The exact aetiology of hip dysplasia is unknown but thought to be multifactorial in nature with the majority of cases probably related to ligamentous laxity in utero induced by maternal hormones, although a breech intrauterine presentation and positive family history are also 2,4,5 recognised risk factors. Early diagnosis of hip dysplasia is critical if long-term disability is to be avoided and, therefore, it is routine practice in the UK for a physical examination of the neonate’s hips to be undertaken by a paediatric physician within a few days of birth. Where the physical examination is posi- tive, ultrasound assessment should be undertaken11 to assess the anatomical 1 position of the cartilaginous femoral head relative to the acetabulum. The femoral head should be seen within the lower medial quadrant of the cross made by Hilgenreiner’s line and Perkin’s line. Ultrasound is the imaging modality of choice to assess the hip of a neonate or young infant but its role in the management of hip dysplasia declines with the increasing ossification of the femoral head as this reflects the beam and prevents accurate assessment of the acetabulum. In older infants, plain film radiography of the hip and pelvis are therefore requested in preference to ultrasound. The Von Rosen projection, which is still described in many radiological texts, is no longer recommended6. Instead, radiographic diagnosis of DDH is undertaken on an antero-posterior projection of the pelvis with the feet positioned vertically and follows careful evaluation of the position of the ossified femoral epiphysis rela- tive to Hilgenreiner’s line (a horizontal line connecting the supero-lateral borders of the triradiate cartilages), Perkin’s line (a vertical line through the lateral rim of the acetabulum) and Shenton’s line (an arc formed by the medial surface of the proximal femur and the inferior margin of the superior pubic ramus) and the 12 acetabular angle which, if greater than 30°, is highly suggestive of dysplasia (Figs 8. Perthes’ disease Legg-Calvé-Perthes’ disease is the idiopathic juvenile avascular necrosis of the 5 femoral head. It presents more frequently in boys than girls (M:F = 4:1) and is normally unilateral, although non-simultaneous bilateral presentations have 4,5 been noted in 10–20% of cases.
